By D.Ta.
Published on 02/11/25 at 08:16 - Updated on 02/11/25 at 08:22

The ARS Paca has been alerted to several cases of measles that have occurred in recent days at the prestigious Thiers high school in Marseille. This highly contagious disease requires students and staff to check whether their vaccinations are up to date.

This is information that is circulating today on the Pronote space of all students attending the establishment. Several cases of measles have been reported in recent days among students in preparatory classes as well as among a teacher at the Thiers high school in Marseille.

The ARS Paca has sent its recommendations to the management team for families faced with this highly contagious disease, with one sick person potentially being able to contaminate " 20 other people ".

Precautions to take

In fact, all people who have attended the Thiers high school since January 2025 are considered contact persons. According to the Regional Health Agency, " it is imperative to check whether vaccination has been carried out: two doses of vaccine are necessary to protect against the disease ," it specifies. However, having had measles is a protection.

In the absence of vaccination, " it is imperative to go to your doctor and start vaccination without delay ," continues the ARS Paca. If only one dose of vaccine has been administered, a second injection must be given. If the first dose was administered before the age of 12 months, a third dose is necessary ." Finally, in the event of an illness leading to a drop in immunity or in the event of pregnancy, you should immediately contact the doctor who is monitoring you to start prevention. Please note that pregnancy does not allow vaccination.

Monitoring for the appearance of signs suggestive of the disease is necessary for at least 15 days: fever, "cold", cough, conjunctivitis, discomfort in light, appearance of pink or red "spots" starting behind the ears and on the face and spreading over the body. In the event of symptoms, you must wear a mask, isolate yourself and consult your doctor, specifying that you have been in contact with a person with measles. He must report it to the ARS.

Measles epidemic in Morocco: recommendations for travelers and reinforcement of precautionary measures for health professionals

In the face of the measles epidemic currently raging in Morocco, Public Health France is reminding people of the importance of vaccination when planning a stay and is calling for vigilance from health professionals during school holidays.
Published on February 14, 2025

Morocco is facing a resurgence of measles cases that has continued to grow since September 2023. The epidemic has reached a historic level and totals nearly 25,000 suspected cases, including 6,300 confirmed cases and 120 deaths. This situation is particularly worrying during school holidays, when travel and family reunification can promote the spread of the virus. A national catch-up campaign for children under 18 was organized from October 28, 2024 to January 27, 2025 by the Moroccan authorities in order to stop the spread of the virus. In this context, Public Health France reminds travelers of the importance of checking their vaccination status with their doctor before leaving and calls on healthcare professionals to be vigilant when treating patients returning from a stay in Morocco.

Increase in imported cases of measles in France from Morocco

Since January 1, 2025, there has been a notable increase in the number of imported cases of measles in France:

• 13 imported cases or cases linked to an importation following a stay in Morocco have been declared since the beginning of the year in several regions in France compared to 26 cases in 2024, i.e. a total of 39 imported cases or cases linked to an importation between 2024 and 2025.
• Children under 5 years old (12 cases) and young adults (20 cases) are particularly affected.
• The vast majority of these cases are unvaccinated (23 cases) or unaware of their vaccination status (9 cases).
• Of the 39 cases reported in 2024 and 2025, 26 were hospitalized, including 11 during the month of January 2025.

Specific recommendations for travelers to Morocco

When visiting a healthcare professional, whatever the reason, any consultation is an opportunity to check your vaccination status.
In addition to the recommendations of the vaccination schedule in force for people born since 1980 and aged at least 12 months, specific recommendations, often overlooked, exist for people who have to travel to an area of ​​high endemicity, such as Morocco currently.

The vaccine is effective in more than 95% of cases after two doses​

For infants: MMR (measles, mumps, rubella) vaccination can be given as early as 6 months of age when travelling to protect them during their stay. Vaccine immunity begins to develop rapidly within a week of the first dose. These infants should then receive two doses of trivalent MMR vaccine according to the vaccination schedule (1 dose at 12 months of age, then one dose between 16 and 18 months).

For people born before 1980 who are not protected against measles (no known history of measles or not previously vaccinated): one dose of MMR vaccine is recommended before departure.

Reminders on measles vaccination

In France, all children, adolescents and young adults born after 1980 must be vaccinated against measles. It is mandatory before entering the community for all infants born since January 1, 2018 (first dose at 12 months and second dose between 16 and 18 months).

For people who have not been vaccinated or have not been fully vaccinated, born since 1980 and aged at least 12 months, a catch-up vaccination is recommended regardless of their history with regard to the three diseases (measles, mumps, rubella - MMR). They can receive two doses, respecting a minimum period of one month between the two doses, or even three doses for people who received a first dose of vaccine before the age of 12 months.​

Vigilance for health professionals when treating patients returning from countries where measles is circulating

Frequent travel to Morocco is expected due to school holidays and the approach of religious holidays. It is therefore important to increase the vigilance of healthcare professionals, in medical practices and emergency rooms, when treating patients with symptoms suggestive of measles and returning from a stay in Morocco (or a country where measles is circulating).

Due to the high contagiousness of the measles virus, additional precautions and isolation measures are necessary to limit any transmission of the virus in healthcare settings.
Vaccination is recommended for all healthcare professionals who are not immunized or have an uncertain vaccination or disease history, including those born before 1980.

Resurgence of measles cases in the region and worldwide: recommendations for users and health professionals

Health alert
March 3, 2025

Faced with the increase in measles cases worldwide and the epidemic currently affecting Morocco, health authorities are asking health professionals to pay particular attention to patients traveling to a country where measles is circulating. The Regional Health Agency also recommends that users check their vaccination status and, if necessary, get vaccinated.

A resurgence in France and the region, with an ongoing epidemic in Morocco

In November 2024, the World Health Organization observed an increase in measles cases worldwide. Measles is circulating particularly in Asia, Africa and Eastern Europe.

In Auvergne-Rhône-Alpes, only one case was reported in 2021, compared to 73 in 2023 and 139 in 2024. Most of the clustered cases in the region originated from an unvaccinated traveler returning from a stay in a country affected by measles (Dubai, India, Romania, etc.).

17 cases have been reported in the region since the beginning of the year .

In recent months, an epidemic has been particularly raging in Morocco. However, since January 2025, French health authorities have observed a notable increase in the number of imported cases of measles from Morocco .

Measles, a disease to be taken seriously

Measles is a highly contagious disease: in the absence of preventive measures, one patient can infect up to 20 people.

It can lead to severe complications (respiratory, neurological) which may require hospitalization , leave after-effects , or even cause death .

Since the disease is transmitted through the air, adults, like children, can come into contact with the measles virus in many circumstances: at daycare, at school, at work, during indoor activities, in a waiting room, etc.

Given the resurgence of cases worldwide, certain destinations may also prove particularly risky.

Vaccination remains the best protection against severe forms

Vaccination is mandatory for children born since January 1 [SUP], [/SUP] 2018 : 1st [SUP]injection[/SUP] at 12 months and 2nd [SUP]injection[/SUP] at 16-18 months.
To be well protected against measles, everyone born since 1980 must have received 2 doses of vaccine.
Before 1980, measles was common in France: people born before this date therefore have a high probability of having contracted this disease and of being immune.
People born after 1980 and/or parents are therefore invited to check their vaccinations and those of their children , by identifying one of the vaccine names below in the vaccination record:

1. Monovalent measles vaccine: Rouvax®
2. Bivalent vaccine against measles + rubella: Rudi-Rouvax®
3. Trivalent measles + mumps + rubella (MMR) vaccine:
   - ROR® / Trimovax® / ROR Vax® (marketed before 2028)
   - Priorix® / MMR Vax Pro® (marketed since 2018)

In the event of non-vaccination or incomplete vaccination , you should consult a doctor or pharmacist quickly, with your health record.

Recommendations for healthcare professionals

The Ministry of Health has alerted health professionals to this situation so that they can:

1. Check the vaccination status of their patients.
2. Apply the specific recommendations for patients planning to travel to a country where measles is circulating - or returning, namely the administration of a dose of MMR vaccine. It is recommended for:

1. Infants from 6 months of age: these children will subsequently need to receive two doses of trivalent MMR vaccine according to the vaccination schedule (1 dose at 12 months of age, then one dose between 16 and 18 months)
2. people born before 1980 who are not protected against measles : with no known history of measles or not previously vaccinated.

Measles is a notifiable disease , which requires special treatment as soon as it is suspected.

Measles: Ministry of Health calls for vigilance due to resurgence of cases

Highly contagious, measles appears to be experiencing a resurgence of cases in France. An epidemic in Morocco, among other places, raises fears of a wider spread of the disease during the holidays.

Ouest France

Published on11/03/2025 at 11:55

In a document sent to health professionals on Friday, March 7, 2025, the Ministry of Health warned of the resurgence of measles . "The epidemiological situation observed in particular since the beginning of the year, gives rise to fears, given the high contagiousness of the disease, of a wider spread across the national territory in the coming weeks," it is written in this document.

Measles is characterized by fever associated with a pinkish rash and possibly conjunctivitis, rhinitis or cough. Small whitish and bluish spots may also appear in the mouth of an infected person. Recovery usually occurs after two to three weeks.

An epidemic in Morocco

This disease is highly contagious. It can be transmitted by direct contact or through the air, five days before and up to five days after the rash appears.

Holidays abroad are particularly feared to increase cases. Public Health France issued a warning in mid-February about the measles epidemic raging in Morocco. In six weeks, since January 1 , the public institution had already recorded 13 cases linked to a stay in Morocco, compared to 26 cases over the whole of 2024. Among these cases imported from Morocco, Public Health France reported 11 hospitalizations in January alone.

Infants under one year of age, pregnant women and people with compromised immune systems are particularly at risk of developing severe disease. Vaccination has been mandatory for all children since 2018, but it begins at 12 months of age.

DATE: 07/03/2025 REFERENCE: DGS-URGENT N°2025_08
TITLE: REINFORCED VIGILANCE IN THE FRAMEWORK OF THE RECRUDESCENCE OF MEASLES IN
FRANCE
...
Ladies and Gentlemen,

The Directorate General of Health (DGS) calls for increased vigilance from all health and early childhood professionals regarding the early detection of measles and the implementation of appropriate preventive measures due to a recent increase in the number of cases in France, on the European continent and worldwide since 2023.

The epidemiological situation observed in particular since the beginning of the year, gives rise to fears, given the high contagiousness of the disease, of a wider spread across the national territory in the coming weeks. High vaccination coverage of the population of all ages, including health professionals or those working in contact with children, is essential to limit viral circulation and protect the most vulnerable.

A. Early detection of cases, confirmation and diagnosis

− The clinical diagnosis of measles should be considered in any patient, regardless of their vaccination status, in
the presence of a fever ≥ 38.5°C associated with a maculopapular rash and at least one of the following signs:
conjunctivitis, rhinitis, cough, Köplik sign. Patients are contagious 5 days before the onset of the rash and
up to 5 days after the onset of the rash;

− Biological confirmation is essential, preferably by oropharyngeal swab and gene amplification by RT-PCR. Viral
RNA is detectable from a few days before the onset of the rash to about 10 days after. The search for IgM, salivary
(Oracol© Kit) or serum, is also possible and should only be carried out from the 3rd day after the onset of the rash
(see appendix, figure 2).

B. Early reporting

Any clinically suggestive case (including before the biological results) must be reported without delay
to the regional focal point of the regional health agency (ARS) by any appropriate means (telephone, email) AND
obligatory sending of the mandatory reporting form even if all the items could not be filled in, they can be
completed later.​

Key points

• From January 1 to March 14, 2025, 180 cases of measles were reported compared to 83 over the same period in 2024, a little more than double. The three age groups most affected are infants under one year old (14%), children aged 1-4 years (21%) and adults aged 30-39 years (14%), who represent nearly half of the cases.
• Hospitalization was reported in 82 cases (45.6%) (including 6 in intensive care), and complications (including 20 pneumonias and 1 encephalitis) in 35 cases (19.5%). Hospitalizations and complications mainly affected infants and young children, but also young adults.
• 70.5% of cases occurred in subjects who were not or incompletely vaccinated.
• 34 departments in mainland France (33.6%) reported at least one case. No cases were reported overseas. More than half of the reported cases concerned five departments: Nord (55 cases), Val d'Oise (15 cases), Bouches du Rhône (13 cases), Ain (9 cases), and Alpes Maritimes (9 cases).
• Over the period, 30 cluster cases (grouping of epidemiologically linked cases) were reported to the Regional Health Agencies (ARS) (unconsolidated provisional data), generating a total of 113 cases. Among them, 7 cluster cases had more than 5 cases and concerned people from the Roma community or of Romanian origin who were settled, the others having occurred in communities (nurseries, high schools), in hospitals, in families, except for one cluster case which occurred following attendance at a Parisian exhibition.
• Of the 180 cases, 20% (36 cases) were imported cases (notion of a stay abroad during the 7 to 18 days preceding the eruption):
  • Importing countries include Morocco (22 cases), Romania (3 cases), Italy (3 cases), Switzerland and Vietnam (3 cases each), the Philippines and the United Kingdom (1 case each).
  • These imported cases were at the origin of chains of transmission on French territory leading to the occurrence of 11 grouped cases involving 27 contaminated cases on the national territory: 19 linked to cases imported from Morocco (mainly in the close entourage of the cases or in healthcare settings), 7 linked to a case imported from Italy (nursery) and one linked to a case imported from Vietnam (family).
  • The historic epidemic situation currently affecting Morocco since the end of 2023 has led to 41 cases in France since the beginning of 2025 (23% of the total number of cases): 22 cases following a recent stay in Morocco and 19 linked to an importation from Morocco. Spain also reported numerous cases of measles imported from that country.
• The prompt reporting of cases to the ARS and the sending of biological samples to the National Measles Reference Centre (CNR) are essential for early identification of cluster cases and the implementation of post-exposure prevention and prophylaxis measures around cases, particularly within communities.

Measles: call for increased vigilance in the face of the resurgence of cases in France and Europe

Public Health France joins forces with the Ministry of Health and Access to Healthcare in calling on healthcare and early childhood professionals to be extra vigilant in the face of the increase in measles cases in mainland France. The virus's high contagiousness and the spring season, which is conducive to its spread, require enhanced prevention and surveillance measures.

Published on March 20, 2025

Since the beginning of 2025, mainland France has been facing a resurgence in measles cases . This increase comes in a context marked by epidemic outbreaks in Europe and around the world. The winter season and early spring are periods conducive to the spread of measles, which increases the risk of the virus spreading throughout the country given its high contagiousness.​

Health and early childhood professionals are urged to increase their vigilance in order to quickly detect cases as soon as they are suspected and to limit transmission.

Epidemiological situation of measles in France

In France, between January 1 and March 14, 2025, 180 cases of measles were reported, compared to 83 in 2024 over the same period, i.e., slightly more than double the number of cases compared to last year. These cases particularly affect children aged 1-4 (21.1%), infants under one year old (14.4%), young adults aged 30 to 39 (13.9%), and those over 40 (10.5%).

Among them, 82 (45.6%) were reported as being hospitalized (6 in intensive care), 35 (19.5%) presented a complication (including 20 pneumonias and 1 encephalitis).
In total, approximately 20% are imported from 7 different countries. Since the beginning of the year, there has been a notable increase in the number of imported measles cases, particularly from Morocco, where a historic epidemic is currently raging: 41 imported cases or cases linked to importation following a stay in Morocco have been reported since the beginning of the year in several regions of France, compared to 26 cases in 2024.

The virus is circulating in several departments of mainland France:

• Thirty-four departments (33.6%) reported at least one case.
• The most affected French departments are the North (55 cases), Val d'Oise (15 cases), Bouches du Rhône (13 cases), Ain and Alpes Maritimes (9 cases each).
• Since the beginning of the year, 30 clusters of measles, resulting in 113 cases, have been reported to the Regional Health Agencies. Among these, seven measles outbreaks with more than five cases were reported in the Nord, Ain, Alpes-Maritimes, Bouches-du-Rhône, and Côte d'Or/Saône-et-Loire.
• These outbreaks involved people from the Roma community or settled people of Romanian origin. Other outbreaks occurred in community settings (nurseries, high schools) or within hospitals or in connection with large gatherings (Parisian exhibition halls).

Health and early childhood professionals play a central role


Faced with this situation, Public Health France is fully mobilized with professionals and reminds that:

• Measles is a disease that must be reported upon clinical suspicion (without waiting for laboratory results).
  • Mandatory declaration form
  • Reporting and notification of measles cases
• Control measures should be implemented around a suspected case among family and extra-family contacts (search for other cases, isolation in the waiting room, measures to exclude people from communities, identification of people in contact in communities or at risk of severe forms, post-exposure prophylaxis measures where appropriate).
• Vaccination is an effective preventive measure: as such, it is important to check your vaccination status and, if necessary, catch up on vaccinations in accordance with the recommendations of the vaccination schedule . Vaccination of healthcare and early childhood professionals, particularly those who are in contact with children or immunocompromised people, is particularly important.
• Travelers planning to visit a country where measles is endemic or in an epidemic phase are advised to update their vaccination status, namely: one dose of MMR vaccine for infants from the age of 6 months, and for people born before 1980 who are not protected against measles.
  • Health recommendations for travelers | Ministry of Labor, Health, Solidarity and Families

Regarding the risk of importing cases from Morocco, awareness-raising actions for travelers were carried out among professionals in February 2025, in particular with the publication of two news items:

• Measles outbreak in Morocco: recommendations for travelers and increased precautionary measures for healthcare professionals | santépubliquefrance.fr
• Measles outbreak in Morocco: recommendations for travelers and precautionary measures for healthcare professionals | Vaccination Info Service

High vaccination coverage of the population of all ages, including health professionals and those working in contact with children, is essential to limit viral circulation and protect the most vulnerable from measles complications.​

Faced with this situation, the mobilization of everyone is essential to prevent the spread of measles and protect the most vulnerable populations.

Resurgence of measles cases: recommendations for users and health professionals

Health alert
March 28, 2025

The measles epidemic affecting the entire world is also impacting the region, notably with the reporting of a cluster in Isère. The ARS recommends that users check their vaccination status and, if necessary, get vaccinated. Health authorities are also asking healthcare professionals to pay special attention to patients traveling to a country where measles is circulating.

A resurgence in France and the region

In November 2024, the World Health Organization observed an increase in measles cases worldwide. Measles is particularly prevalent in Asia, Africa, and Eastern Europe. In recent months, an epidemic has been particularly severe in Morocco. However, since January 2025, French health authorities have observed a significant increase in the number of imported measles cases from Morocco .

In Auvergne-Rhône-Alpes, only one case was reported in 2021, compared to 73 in 2023 and 139 in 2024. Most of the clustered cases in the region originated from an unvaccinated traveler returning from a stay in a country affected by measles (Dubai, India, Romania, etc.).

A cluster identified in Isère in March 2025

Between March 12 and 27, 2025, around fifteen cases of measles were reported in Isère . Twelve cases have been biologically confirmed and the other cases are currently being analyzed.

According to the investigations, the cases were likely infected within the family or school setting (classes, activities, transportation). As soon as the cluster was identified, the ARS informed the mayors of the municipalities where the cases resided, as well as the heads of the schools concerned, to alert parents. The ARS also raised awareness among healthcare professionals in the sector.

A vaccination campaign is being organized starting Monday, March 31st and will continue throughout the week at the Côte-Saint-André agricultural high school, as well as at the Saint-François Sainte-Cécile Institution located in the same town. It is aimed at all students and staff whose vaccination schedule is incomplete.
At the same time, the ARS recommends the suspension of planned school trips in order to limit the spread of the virus.
Depending on how the situation develops, other measures may be implemented in other schools.

Residents are urged to be especially vigilant if symptoms appear and to check their vaccination status. If in doubt, consult a healthcare professional with your health record.

BFMTV INFO. Measles: Several cases identified "among people who attended the Agricultural Show"

Caroline Dieudonné and Tom Kerkour
Today at 6:30 a.m.

Health authorities have been informed of the emergence of cases of measles among several people who attended the Paris Agricultural Show held from late February to early March. "The cases are located in Île-de-France, Auvergne-Rhône-Alpes, Normandy, and Occitanie," the Ministry of Health told BFMTV.

Is the rise in measles cases in France partly due to infections during the Agricultural Show, which brought together thousands of people?

The Ministry of Health, contacted by BFMTV, explained that "health authorities have been informed of situations involving a risk of viral spread by several regions concerning cases of measles among people who attended or worked at the Paris Agricultural Show." As a reminder, the show was held from late February to early March in Paris, with 607,503 visitors at this 61st edition.

These cases have been identified in Île-de-France, the Auvergne-Rhône-Alpes region, Normandy, and Occitanie. Their number has not been indicated. The situation has been closely monitored in recent months. In a previous communication, the ministry had called for increased vigilance among healthcare professionals given an increase in France, on the European continent, and worldwide since 2023. Compared to last year, cases have doubled according to Public Health France :

"From January 1 to March 14, 2025, 180 cases of measles were reported compared to 83 over the same period in 2024, i.e., a little more than double," the health agency stated on March 20.
The disease, which is recognizable by its skin rash, causes coughing, fatigue, and high fever. It mostly presents mild forms, but spreads like wildfire.

A cluster in Isère after a visit to the trade fair

While this is a highly contagious disease, the ministry stated that measures are being taken to "limit the risk of spread," adding that health authorities are "still closely monitoring the situation." SIA professionals and exhibitors have also been informed of this risk and are urged to seek medical advice if symptoms appear.

At least one cluster originated after a visit to the fair , as Health Minister Yannick Neuder explained to the Dauphiné. "The infection began with a person attending the Côte-Saint-André agricultural high school. They are believed to have contracted the virus during an outing to the Agricultural Show. It then spread to other people at the same establishment," he told our colleagues.

The region's Regional Health Agency announced on Friday, March 28, that it had detected several cases of measles between March 12 and 27, while warning that it should be "particularly vigilant with all those who had attended this fair," Anne-Sophie Ronnaux-Baron, a public health doctor and head of the regional health monitoring unit at the Auvergne-Rhône-Alpes Regional Health Agency, explained to BFMTV.

Contaminations in schools and families, twelve of which have been biologically confirmed. Three others are currently being verified. "We had this information that cases were circulating at the agricultural fair, so there was an initial case, which contaminated other cases, in the case of a chain of transmission in schools."

"It is important to know that measles is an extremely contagious disease linked to a virus and that one infected person can infect 20 others who are poorly or not vaccinated at all," she said.
In Isère, a catch-up campaign will be offered in three schools starting March 31 for people who have not been vaccinated or who do not have a complete vaccination schedule.

Measles epidemic: the Agricultural Show at the origin of an epidemic cluster

Joanna Chabas with Guillaume Descours
Today at 9:41 a.m.

A measles vaccination campaign began this Monday. Several outbreaks have been identified across the country, in Île-de-France, Normandy, Occitanie, and also in Auvergne-Rhône-Alpes. All of them have in common the fact that they attended or were in contact with visitors to the Paris Agricultural Show at the end of February.

The Paris Agricultural Show could be the source of a resurgence of measles . Several cases have been detected in Île-de-France, Auvergne-Rhône-Alpes, Normandy, and Occitanie. Individuals attending the International Show from late February to early March were affected.

In Isère alone, 18 cases have been reported. Authorities are trying to contain the cluster. Students from an agricultural high school in Côte-Saint-André, between Grenoble and Lyon, contracted measles during a trip to the Paris Agricultural Show. The virus then spread to other people in the high school and sports clubs.

Since then, students and staff have been wearing masks, and school trips have been suspended. And health authorities are organizing a vaccination campaign starting this Monday in two schools in the department. Because the vaccine remains the only way to fight measles, explains infectious disease specialist Benjamin Davido.

“To contain this measles, ideally, we need more than 95% of people vaccinated. And despite the vaccination requirement, we know that we're closer to 90% than 95% of the target. We don't have any treatment elsewhere. We have work to do to achieve this goal,” he emphasizes.

A highly contagious disease

He encourages the show's more than 600,000 visitors to make sure their vaccinations are up to date. Especially since measles is extremely contagious . One patient can infect up to 20 people.

Health authorities, however, remain vigilant. The Minister of Health announced that further vaccination campaigns would be organized in the event of new clusters.

ARS Normandy calls for vigilance in the face of the resurgence of measles

Press release

April 9, 2025

ARS Normandy calls for vigilance in the face of the resurgence of measles

Mainland France has been facing a resurgence in measles cases since the beginning of the year, amid epidemic outbreaks in Europe and around the world. Normandy is also experiencing an increase in the number of cases. In this context, the Regional Health Agency of Normandy (ARS) reiterates that vaccination is an essential preventive measure that ensures both individual and collective protection by reducing the spread of the virus.

Since the beginning of the year, France has seen a resurgence in measles cases. Normandy is also affected: as of April 9, seven mild cases of measles have been identified in several Norman departments (in Eure, Manche, and Seine-Maritime) for 2025, compared to 10 cases for all of 2024. No cluster cases have been recorded in communities.

Symptoms and transmission of measles

Measles is a viral infection, one of the most contagious childhood infectious diseases. The virus is transmitted through the air.

It manifests itself by the appearance of a high fever (above 38.5°C), persistent cough, rhinitis or conjunctivitis and a skin rash. The rash lasts 5 to 6 days.

It naturally evolves towards healing in the vast majority of situations.

The most complicated forms mainly affect patients aged less than 1 year and over 20 years.

Vaccination is the best protection

The ARS Normandie reminds that vaccination is an essential preventive measure that ensures individual and collective protection, by reducing the spread of the virus. It is therefore recommended to check your vaccination status in order to proceed, if necessary, to catch up in accordance with the recommendations of the vaccination schedule .

All children and young adults should be vaccinated against measles. It is a highly effective vaccination that protects against the disease in nearly 100% of cases after two doses. This is why, since January 1, 2018, the measles vaccination has been one of the 11 mandatory childhood vaccinations. Parents are encouraged to contact their healthcare professional (general practitioner, pediatrician, etc.) as part of their child's follow-up to ensure this mandatory vaccination is completed.

Travel recommendations include, in the context of travel to an endemic country or during an epidemic, the administration of a dose of MMR vaccine for infants from the age of 6 months.

Measles cluster in Isère: 22 cases now reported, new vaccination campaign launched

Tom Kerkour
Yesterday at 5:50 p.m.

The Regional Health Agency (ARS) of the Auvergne-Rhône-Alpes region has provided an update on the measles cluster in the Isère department. Twenty-two cases have been reported, with infections occurring "in the family or school setting."

The number of reported measles cases in Isère continues to rise. On Wednesday, April 9, the Auvergne-Rhône-Alpes Regional Health Agency (ARS) announced the reporting of 22 cases of this highly contagious disease, compared to around fifteen on March 28.

"Between March 12 and April 7, 2025, 22 cases of measles were reported in Isère, 18 of which were biologically confirmed. According to the investigations, the cases were infected within the family or school setting (classes, activities, transportation)," the health agency explained in a press release.

The Agricultural Show as a starting point

According to BFMTV, the origin of this cluster in Isère is the visit of a person to the International Agricultural Show, where at least 13 cases were reported among visitors and exhibitors. The sick person then returned to their department where they in turn infected several others.

"There was a first case, which contaminated other cases, as part of a chain of transmission in schools," Anne-Sophie Ronnaux-Baron, head of the health monitoring unit at the ARS, explained to BFMTV.

New vaccination campaign

As specified by the ARS, since March 31, a catch-up vaccination campaign has been underway to immunize residents living near identified cases who have not been vaccinated at all or have not received the two necessary doses.

In Isère, about a hundred people have been vaccinated since March 31. The campaign, which began in local high schools, will continue on Friday, April 11, in two new locations.

In France, vaccination coverage is estimated at only 90% , while a rate of 95% is considered necessary to stop infections. Since 2018, two doses of vaccine have been mandatory for young children before the age of 18 months. In the Île-de-France region, for example, several people who have contracted measles since March were not vaccinated or not fully vaccinated.

The other outbreaks of measles cases have not led to the implementation of large-scale catch-up vaccination campaigns, as the Ministry of Health explained to BFMTV on April 1.

Vigilance remains essential in France and abroad. Other countries, such as Morocco and the United States, are also facing a significant increase in cases of this volatile disease.

Health: Ten cases of measles reported in the Annecy area

MR - Yesterday at 7:59 PM | Updated yesterday at 8:12 PM -

In recent days, parents of students attending schools in the Annecy area have been informed of the return of measles. A letter headed by the Grenoble academy and the regional health agency (ARS) states that “several cases of measles have been confirmed” in “school-aged children” and adults “residing in Haute-Savoie,” some of whom “have experienced complications requiring hospitalization.” The message invites parents to check the vaccination records of the entire family and, if necessary, “to promptly update their vaccinations.”

The ARS, which we contacted on Tuesday, April 15, reported that "ten cases of measles have been confirmed to date in the Annecy area," without providing further details. A highly contagious and immunizing disease, measles develops in epidemics. In recent weeks, a cluster has been identified in Isère , with 22 cases, 18 of which have been biologically confirmed. The vaccination schedule consists of administering two doses of the MMR vaccine to babies between 12 and 18 months. Catch-up vaccination is recommended for unimmunized and unvaccinated children and adults.

Measles in France. Bulletin of April 29, 2025.


Published on April 29, 2025
Updated on April 29, 2025

Key points

• From January 1 to April 13, 2025, 427 cases of measles were reported to the Regional Health Agencies (ARS), a total approaching the number of cases (483) reported in 2024. The four age groups most affected, representing nearly half of the cases, are children aged 1-4 years (17%), adolescents aged 15-19 years (10%), adults aged 30-39 years (11%) and adults over 40 years (14%). The highest case notification rate is observed among infants under one year of age (6.6 cases per 100,000).
• For 143 (33.5%) cases, a visit to the emergency room or hospitalization was reported (including 9 in intensive care), and for 58 (13.6%) cases, a complication (including 36 pneumonias and 1 encephalitis). One death was reported in an immunocompromised adult patient. Hospitalizations and complications mainly affected infants and young children but also young adults.
• Among the subjects targeted for vaccination (aged over one year and born since 1980), for whom vaccination status was known (n=304), 208 (68.4%) cases occurred in subjects who were not or incompletely vaccinated.
• Sixty departments in mainland France have reported at least one case, representing more than half (59.4%) of the departments. No cases have been reported in Overseas France. More than half of the reported cases concerned nine departments: Nord (76 cases), Isère (30 cases), Haute-Savoie (23 cases), Bouches du Rhône (20 cases), Val d'Oise (19 cases), Hérault (17 cases), Paris (15 cases), Alpes Maritimes (13 cases), and Pas de Calais (12 cases).
• During this period, 56 cluster cases (grouping of epidemiologically linked cases) were reported to the Regional Health Agencies (ARS) for a total of 245 cases. Among them, 14 cluster cases had 5 or more cases.
• Of the 427 reported cases, 65 (15%) were imported cases (notion of a stay abroad during the 7 to 18 days preceding the eruption).
• The prompt reporting of cases to the ARS and the sending of biological samples to the National Measles Reference Centre (NRC) are essential for early identification of cluster cases and the implementation of post-exposure prevention and prophylaxis measures around cases, particularly within communities.

Measles in France. Bulletin of June 23, 2025.

Published on June 23, 2025
Updated on June 23, 2025

Key points

• From January 1 to May 31, 2025, 658 cases of measles were reported to the regional health agencies (ARS), a total already exceeding by more than 35% the number of cases reported in 2024 (483). At the national level, the number of reported cases appears to have peaked in March but remains at a high level, particularly in certain regions.
• The four age groups most affected, representing nearly half of the cases, were children aged 1-4 years (15%), adolescents aged 15-19 years (13%) and 10-14 years (12%), and adults over 40 years (12%). The highest measles case notification rate was observed among infants under 1 year of age (9.6 cases per 100,000).
• For 222 cases (33.7%), a visit to the emergency room or hospitalization was reported (including 10 in intensive care), and for 87 cases (13.2%) a complication (including 50 pneumonias and 1 encephalitis). Two deaths were reported in immunocompromised patients. Hospitalizations and complications mainly affected infants and young children as well as young adults.
• Among the subjects targeted for vaccination (aged over 1 year and born since 1980), for whom vaccination status was known (n=429 cases), 304 (70.8%) cases occurred in subjects who were not or incompletely vaccinated.
• Sixty-three departments in mainland France reported at least one case, representing more than half of the departments (62.4%). No cases were reported overseas. More than half of the reported cases concerned nine departments: Nord (117 cases), Bouches-du-Rhône (50 cases), Isère and Haute-Savoie (39 cases each), Hérault (27 cases), Paris (25 cases), Seine-Saint-Denis (22 cases), Pas-de-Calais (22 cases), and Val d'Oise (20 cases).
• During this period, 86 cluster cases (grouping of epidemiologically linked cases) were reported to the ARS, totaling 370 cases. Among them, 18 cluster cases included 5 or more cases.
• Of the 658 reported cases, 94 (14%) were imported cases (notion of a stay abroad during the 7 to 18 days preceding the eruption).
• The prompt reporting of cases to the ARS and the sending of biological samples to the National Measles Reference Centre are essential for early identification of cluster cases and the implementation of post-exposure prevention and prophylaxis measures around cases, particularly within communities.
• Strengthening catch-up vaccination efforts is crucial during this period. Any contact with a healthcare professional should be an opportunity to check the vaccination status of people born since 1980. Vaccination with the MMR vaccine is indeed the best way to protect yourself from the virus but also to protect vulnerable people at risk of severe forms (infants under one year old, pregnant women, and immunocompromised people) who cannot be vaccinated.

Against measles, there is only one protection: vaccination

News
July 29, 2025

Since the beginning of the year, the number of measles cases has been increasing in Occitanie. In a national and international context of a resurgence of this disease, which can be serious, the Occitanie Regional Health Agency reminds us that the best way to protect yourself and limit the spread of the virus is to get vaccinated!

Since the beginning of the year, 90 confirmed cases of measles have been reported to the ARS Occitanie* (735 cases in France). In the majority of cases, infected individuals are unvaccinated or insufficiently vaccinated (only 1 dose).

In Occitania to date, measles-mumps-rubella vaccination coverage (2 doses) is estimated at 85.5% in children aged 33 months, no department has reached 95% vaccination coverage, the rate recommended by the World Health Organization (WHO) to enable the elimination of the disease.

*Source: Public Health France. Number of cases from January 1 [SUP]to[/SUP] June 30, 2025

To protect yourself and the most vulnerable, there is only one thing to do: get vaccinated.

To be effectively protected, there's only one solution: vaccination. The MMR vaccine is recommended from the age of one, but also for adults born after 1980. Check your health record to verify that you are adequately protected. Healthcare professionals, early childhood professionals, and teachers are also strongly encouraged to check their vaccination status. Getting vaccinated also protects the most vulnerable who cannot be vaccinated: infants under 6 months, pregnant women, immunocompromised people, etc.

A highly contagious disease that can be serious

Often mistakenly considered benign, measles can lead to serious complications (pneumonia, encephalitis, etc.) and hospitalizations. Measles is not just a childhood illness; it also affects adolescents and adults. It is characterized by a high fever, associated with a cough, nasopharyngitis or conjunctivitis, followed by a rash.

Measles is 10 times more contagious than the flu; one sick person can infect 10 to 15 people. It is very easily transmitted from one person to another through the air, when coughing, blowing your nose, or by contact with contaminated objects (toys, tissues, etc.). If you think you have measles or if you have been in contact with an infected person, follow barrier measures (wearing a mask, washing your hands, etc.) and contact your doctor quickly.
