St. Martin: Chikungunya epidemic - 1000 + cases - 2 fatalities

[Ronan Kelly]

Island on alert as two cases of Chikungunya confirmed
FRIDAY, 06 DECEMBER 2013 23:52
MARIGOT--Two cases of Chikungunya, a Dengue-like sickness, have been confirmed in St. Martin following testing at the specialist laboratory in Marseille that returned positive results to Agence R?gional de Sant? (ARS) on December 5.
The disclosure was made by ARS Director-General Patrice Richard on Friday at a press conference in the Pr?fecture attended by Pr?fet Philippe Chopin, President of the Collectivit? Aline Hanson, Dutch-side Minister of Public Health Cornelius de Weever and specialist epidemiologists.
Richard said family doctors, for about two weeks, have been reporting cases of people showing suspected signs of Chikungunya, and not Dengue. There is no current evidence that Chikungunya is on the Dutch side. The virus can be imported by travelling from a risk country.
The two confirmed cases originated in French Quarter. In addition, there are currently four "probable" cases and 30 "suspected" cases, 15 of which are in the Oyster Pond area. In technical terms, "suspected" means just the signs are manifested while "probable" is a diagnostic test that calculates the likelihood that Chikungunya has been contracted, according to epidemiologists.
ARS is awaiting more results of other cases from the Marseille laboratory.
"Chikungunya is in the Pacific islands, in Asia, in India, but never until now in the Caribbean islands," noted epidemiologist Marion Petit-Sinturel. "It's the first time we have had a located transmission here in St. Martin."

Chikungunya in the French part of the Caribbean isle of Saint Martin

Disease outbreak news / 10 December 2013


On 6 December 2013, WHO was notified of two laboratory confirmed cases of locally acquired chikungunya disease in the French part of the Caribbean isle of Saint Martin.

The other part of the isle is a country that is part of the Kingdom of the Netherlands (Sint Maarten). These two cases were confirmed by polymerase chain reaction (PCR) test performed by the French National Reference Centre for arboviruses in Marseille.

There has been an outbreak of dengue fever on St Martin / Sint Maarten since January 2013. Chikungunya disease was detected during an investigation following the notification of five cases with joint pains and fever on 18 November 2013, for whom the diagnosis of dengue was excluded. The onset of symptoms of the five cases occurred between 12 October and 15 November 2013.

As of 10 December 2013, altogether two confirmed, four probable and twenty suspected cases of chikungunya infection have been reported.

Chikungunya is a viral disease that is rarely fatal and is transmitted to humans by infected mosquitoes. Symptoms of chikungunya include high fever and headache, with significant pains in the joints (ankles, wrists), which can persist for several weeks. The symptoms appear between 4 and 7 days after the patient has been bitten by an infected mosquito. The name, chikungunya derives from a word in Makonde language roughly meaning ?that which bends up?, reflecting the physique of a person suffering from the disease.

In the absence of specific treatment and an effective human vaccine, preventive measures are based on a dual strategy:

• raising awareness of the risk factors for chikungunya infection as well as the protective measures individuals can take to prevent mosquito bites;
• stopping the proliferation of mosquitoes by reducing their breeding grounds.

This is the first time that locally acquired transmission of chikungunya has been detected in the WHO Americas Region.

The health authorities on both the French and the Dutch side of the island are cooperating closely to respond to this outbreak, in close coordination with public health authorities in France and the Netherlands. Actions implemented by local authorities to-date include:

• Epidemiological surveillance including syndromic surveillance and surveillance of severe cases.
• Vector control activities have been implemented in the affected area and will rapidly be extended to the entire island, including around airports, schools, day nurseries, hospitals.
• Communication and social mobilization: information is being disseminated to health professionals, to the public (on individual protection, how to eliminate the larvae breeding ground) and to the travelers by specific information in the airports.

WHO does not advise special screening at points of entry with regard to this event nor does it currently recommend the application of any travel or trade restrictions.

Re: St. Martin: 1st incidence of Chikungunya local transmission

ProMED comment;


[The occurrence of a chikungunya epidemic in the Caribbean area is of concern, but perhaps not surprising. The tropical Americas, including Caribbean Islands, harbor abundant populations of the chikungunya virus mosquito vector, _Aedes aegypti_.

This virus has been introduced in various areas of the world by viremic travelers into localities where the vector is present, with initiation of ongoing transmission. It seems that it has just been a matter of time until an outbreak occurs in the Americas.

The French and Dutch health authorities on St Martin are to be commended for quickly mounting a coordinated effort that includes both French and Dutch sides of the island. One hopes that their efforts for vector control and surveillance are successful and bring the relatively small outbreak to a halt, without further spread on the island or to other areas in the Caribbean.

Chikungunya -Saint Martin- 2013 autochthonous cases

Opening date: 9 December 2013 Latest update: 11 December 2013


Epidemiological summary

On 6 December, France confirmed two cases of autochtonous chikungunya in the French part of the Caribbean island of Saint Martin.

These two cases were detected through active case finding, implemented following the notification on 18 November 2013 of a cluster of five cases of arthralgia and fever, for which a diagnosis of dengue was excluded (negative NS1 and IgM).

The onset of symptoms of the five notified cases occurred between 12 October and 15 November 2013.

They were all residents of the Oyster Pond neighbourhood, located on the border with the Dutch part of the island.

On 10 December, WHO reported two confirmed, four probable and 20 suspected cases of chikungunya infection on the island of Saint Martin.


ECDC assessment

Saint Martin is a small island in the Caribbean of around 71 000 inhabitants, divided between France and the Netherlands. Given the size of the island, it cannot be excluded that a similar epidemiological situation might be on-going on the Dutch part of the Island.

Saint Martin is a popular travel destination for EU residents and increased travel can be expected during the Christmas holidays. Therefore, travel related cases of chikungunya, as well as of dengue, returning from the island Saint Martin can be expected. ECDC detailed risk assessment can be found here.

Local authorities on Saint Martin Island are working together in close coordination with public health authorities in France and the Netherlands to implement actions in response to this outbreak. These activities include epidemiological surveillance and vector control activities in the affected area. The measures will rapidly be extended to the entire island, including around airports, schools, hospitals. Information is being disseminated to health professionals to the public and to the travellers in the airports.

Blood safety procedures are already in place due to the on-going outbreak of dengue in Saint Martin.


Actions

ECDC published a rapid risk assessment on 12 December 2013.

Distributed via the CDC Health Alert Network / December 13, 2013, 1400:00 (2:00 PM ET) / CDCHAN-00358

Notice to Public Health Officials and Clinicians: Recognizing, Managing, and Reporting Chikungunya Virus Infections in Travelers Returning from the Caribbean


Summary

On December 7, 2013, the World Health Organization (WHO) reported the first local (autochthonous) transmission of chikungunya virus in the Americas. As of December 12th, 10 cases of chikungunya have been confirmed in patients who reside on the French side of St. Martin in the Caribbean. Laboratory testing is pending on additional suspected cases.

Onset of illness for confirmed cases was between October 15 and December 4. At this time, there are no reports of other suspected chikungunya cases outside St. Martin. However, further spread to other countries in the region is possible.

Chikungunya virus infection should be considered in patients with acute onset of fever and polyarthralgia, especially those who have recently traveled to the Caribbean. Healthcare providers are encouraged to report suspected chikungunya cases to their state or local health department to facilitate diagnosis and to mitigate the risk of local transmission.


Background

Chikungunya virus is a mosquito-borne alphavirus transmitted primarily by Aedes aegypti and Aedes albopictus mosquitoes. Humans are the primary reservoir during epidemics. Outbreaks have been documented in Africa, Southern Europe, Southeast Asia, the Indian subcontinent, and islands in the Indian and Pacific Oceans. Prior to the cases on St. Martin, the only chikungunya cases identified in the Americas were in travelers returning from endemic areas.


Clinical Disease

A majority of people infected with chikungunya virus become symptomatic. The incubation period is typically 3?7 days (range, 2?12 days). The most common clinical findings are acute onset of fever and polyarthralgia. Joint pains are often severe and debilitating. Other symptoms may include headache, myalgia, arthritis, or rash. Persons at risk for more severe disease include neonates (aged <1 month) exposed intrapartum, older adults (e.g., ≥ 65 years), and persons with underlying medical conditions (e.g., hypertension, diabetes, or cardiovascular disease).


Diagnosis

Chikungunya virus infection should be considered in patients with acute onset of fever and polyarthralgia who recently returned from the Caribbean. Laboratory diagnosis is generally accomplished by testing serum to detect virus, viral nucleic acid, or virus-specific immunoglobulin M (IgM) and neutralizing antibodies. During the first week of illness, chikungunya virus infection can often be diagnosed by using viral culture or nucleic acid amplification on serum. Virus-specific IgM and neutralizing antibodies normally develop toward the end of the first week of illness. To definitively rule out the diagnosis, convalescent-phase samples should be obtained from patients whose acute-phase samples test negative.

Chikungunya virus diagnostic testing is performed at CDC, two state health departments (California and New York), and one commercial laboratory (Focus Diagnostics). Healthcare providers should contact their state or local health department to facilitate testing.


Treatment

No specific antiviral treatment is available for chikungunya fever.

Treatment is generally palliative and can include rest, fluids, and use of analgesics and antipyretics. Because of similar geographic distribution and symptoms, patients with suspected chikungunya virus infections also should be evaluated and managed for possible dengue virus infection.

People infected with chikungunya or dengue virus should be protected from further mosquito exposure during the first few days of illness to prevent other mosquitoes from becoming infected and reduce the risk of local transmission.


Prevention

No vaccine or preventive drug is available. The best way to prevent chikungunya virus infection is to avoid mosquito bites. Use air conditioning or screens when indoors. Use insect repellents and wear long sleeves and pants when outdoors. People at increased risk for severe disease should consider not traveling to areas with ongoing chikungunya outbreaks.


Recommendations for Health Care Providers and Public Health Practitioners

• Chikungunya virus infection should be considered in patients with acute onset of fever and polyarthralgia, especially those who have recently traveled to the Caribbean.
• Healthcare providers are encouraged to report suspected chikungunya cases to their state or local health department to facilitate diagnosis and to mitigate the risk of local transmission.
• Health departments should perform surveillance for chikungunya cases in returning travelers and be aware of the risk of possible local transmission in areas where Aedes species mosquitoes are currently active.
• State health departments are encouraged to report laboratory-confirmed chikungunya virus infections to ArboNET, the national surveillance system for arthropod-borne viruses.

New cases of chikungunya confirmed by authorities

MONDAY, 16 DECEMBER 2013 00:44

MARIGOT--Ten more cases of chikungunya have been biologically confirmed with four more classed as "probable" and up to eighty more suspected according to Institut de Veille Sanitaire's (INVS') latest bulletin. Most of the cases reported to date have been in the Oyster Pond area.

The increase in cases since the December 6 announcement of the first two cases comes as authorities concede the spread of the virus will be "inevitable."

However, awareness campaigns for the benefit of the public are in effect on both sides of the island and the regional health authority ARS held an awareness session in the French Quarter marketplace on Rue de Coralita on Saturday.

Stands were set up to give information on dengue and chikungunya with various experts, health professionals, epidemiologists and doctors on hand to assist. Flyers and T-shirts were distributed as well as the tiny golomine fish which eats mosquito larvae. The fish, which are placed in non-potable water cisterns, are one of the effective defences against dengue.

Epidemiological update: Autochthonous cases of chikungunya fever on the Caribbean island of Saint Martin

20 Dec 2013


​As of 19 December 2013, the local health authorities of the French Caribbean Islands reported 26 confirmed and 12 probable autochthonous cases of chikungunya on the island of Saint Martin.

Three foci are identified on the Island namely Oyster Pound, Sandy Ground and quartier d?Orleans but new foci seem to be emerging.

Additional three cases were detected on the Dutch part of the Island, two cases of chikungunya have been confirmed in the island Martinique, according to media quoting regional health authorities, and in Guyane a case imported from Martinique was detected.

This is the first documented autochthonous transmission of chikungunya virus in the Americas. The cluster of suspected cases was detected during an on-going dengue outbreak on the island Saint Martin.

These new developments strengthen the evidence supporting the conclusion and recommendations of the ECDC risk assessment published on 12 December, stating that the risk of spread of the disease to other islands in the Caribbean region is high.

Due to the increased travel during the Christmas holidays, vigilance must be maintained regarding imported cases of chikungunya in the EU, including awareness among clinicians and travel clinics and blood safety authorities.

Since 25 November 2013 , monitoring
weekly suspects is carried
with GPs and paediatricians
of the island. Over the past three weeks,
there has been a steady increase in the number
Weekly suspect ( Figure 1). in

Current epidemiological situation in Martinique
In Martinique , two chikungunya virus infections were confirmed by RT- PCR in two people who showed signs suggestive ( suspect ), one by the CNR of arboviruses in Marseille and the other by the NRC Associate arboviruses at the Pasteur Institute of French Guiana. These two people have not traveled in a risk area two weeks before the onset of clinical signs.
These confirmations reveal a chain of transmission of the virus is established in Martinique which is Phase 2 of Psage in Martinique : moderate indigenous transmission .
Measures enhanced surveillance and vector control should continue and be intensified to prevent secondary cases and outbreaks and avoid the spread of the virus .
The epidemiological surveillance system is based on the support of all clinicians , as well as all city laboratories or hospitals to immediately report any suspected or confirmed cases to the Regional Health Agency , that are conducted in a timely epidemiological investigation and actions of vector control on the case .

Epidemiological update Saint Martin

Untill now 98 cases of chikungunya infection have confirmed; 20 cases are classified as probable.

6 patients (adults) are in hospital.

271 cases are clinical suspect, testresults are pending.

INVS describes the situation as "epidemical" .

Depuis le 25 novembre 2013, la surveillance
hebdomadaire des cas suspects est réalisée
auprès des médecins généralistes et pédiatres

Conclusions générales

L’épidémie de Chikungunya poursuit sa progression sur l’Ile de Saint Martin.

La surveillance
à Saint Barthélemy a également mis en évidence des chaines locales de
transmission. Ces deux territoires sont placés au niveau 3a du Psage* : situation
épidémique.

En Martinique et en Guadeloupe, la confirmation biologique de nouveaux cas de
chikungunya autochtones confirme l’introduction du virus sur ces territoires. La
situation épidémiologique correspond à la phase 2 du Psage* : transmission autochtone
modérée. Les mesures de surveillance renforcée et de lutte antivectorielle doivent
se poursuivre et s’intensifier pour prévenir la survenue de cas secondaires et
l’apparition de foyers.

Pour la Guyane, la situation correspond toujours à la phase 1 renforcée du Psage du
chikungunya dont l’objectif est d’éviter et/ou de contrôler au plus vite l’instauration
d’une chaîne locale de transmission du virus en mettant en place, sans délai, devant

Second chikungunya case confirmed in Cay Hill

THURSDAY, 09 JANUARY 2014

~ Emergency fogging today ~

PHILIPSBURG--The second case of the Chikungunya virus was confirmed in Cay Hill, the Health Ministry's Collective Prevention Services (CPS) announced late Wednesday.

As a result, an emergency fogging cycle will be carried out early today, Thursday, in Cay Hill and Belair. The so-called "shantytown" area in Cay Hill will also be fogged.

During fogging, residents should open their doors and windows. Dishes, bowls, pots and pans, fish tanks and bird cages should be covered and residents should stay away from open windows and doors.

The fogging is part of the campaign to eliminate mosquito breeding sites, CPS said. Fogging will start at 5:00am if the weather permits and residents are being asked to open their doors and windows; persons with respiratory problems should keep them closed.

According to the latest epidemiological reportt of the National Institute of Health Surveillance (INVS) dated 9 January 2014, chikungunya continued to grow, with 201 laboratory confirmed or probable in Saint-Martin (against 80 to December 27) cases and 396 clinical cases.

Since December, eight people were hospitalized, including two children. Two cases have been filed and are not severe. No deaths have been reported.

The increase in the number of consultations was almost constant throughout December, says InVS: between 29 December and 5 January, 125 were identified.

Almost all parts of St. Martin are affected, the greatest concentration remaining in neighborhoods Oyster Pound, Sandy Ground, or Orleans. The dengue epidemic is still running since January 2013.

Chikungunya: first death in St Martin

Friday, January 17, 2014


A person with a severe form of chikungunya died in Saint-Martin. In Guadeloupe, the number of cases is increasing, especially in Baie-Mahault where the outbreak is not under control.

Chikungunya has claimed its first victim. Reaching a severe form of the disease, but also with other pathologies, a person, though hospitalized, died in St. Martin.

This death is considered by health authorities as " indirectly linked" to chikungunya . In the North Island, the epidemic remains very active: from the beginning, the estimated number of suspected cases totaled 490 .
