First autochthonous case of Dengue in Italy - 14 total cases identified in Lodi area

[tetano]

The first Lombard case of Dengue, the disease carried by the Aedes mosquito, commonly known as the tiger mosquito, has been identified. It is an over 70 year old from the province of Lodi, hospitalized in Crema hospital in good condition. This was announced by the welfare management of the Lombardy Region, adding that the prevention departments of the Milan and Valpadana Ats have already defined extraordinary disinfestation actions in the close vicinity of the places frequented by the patient. A few days ago a possible case of Dengue occurred in Monza.

The Ats themselves are preparing a warning note for general practitioners and hospitals with emergency rooms of Asst Lodi-Crema to recognize the symptoms of Dengue and activate specific diagnostic pathways. The case was also reported to the Ministry of Health and the Higher Institute of Health. 'For citizens - recalls the welfare management - it is necessary to protect themselves from mosquito bites, especially for older people or those most at risk from the effects of the disease'. So it is advisable to use mosquito repellents outdoors and insecticides (and mosquito nets) indoors.​

The case of Dengue in Lodi will have to be verified from which side it may have arrived, but autochthonous transmission is possible, because we know very well that Dengue is transmitted by the tiger mosquito. There may have been an undiagnosed case in the area, or an uncertain case and therefore not notified by the hospitals, and a tiger mosquito may have bitten an infected person and then another and evidently this virus would pass from one to the other. other. It is clear that on the one hand these mosquitoes proliferate in large quantities with climate change. So we are realizing that some diseases that are in some areas of the world are now also becoming so in other areas'.

This is the analysis by Matteo Bassetti, director of infectious diseases at the San Martino Polyclinic in Genoa, who comments on the case of Dengue fever recorded in a patient over 70 in the province of Lodi.​

Subject: Measures to prevent the transmission of Dengue virus infection by the
transplantation of organs, tissues and cells.

Following the report of a homegrown confirmed case of Dengue virus (DENV) infection
in the municipality of Castiglione d'Adda (Province of Lodi) reported on the platform for the 'Surveillance
of arboviruses” of the Istituto Superiore di Sanità, it is deemed necessary to have, in addition to
strengthening of anamnestic investigations on the donor, the introduction of the following measures
preventive:
to. Transplantation of deceased donor organs:
It is recommended to perform the specific test for the detection of DENV (PCR), within 72 hours
from the donation, on:
9 all donors residing in the Province of Lodi;
9 out of all donors reported by the Province of Lodi;
9 on all donors who have stayed temporarily (at least for one
night) in the 28 days preceding the donation in the Province of Lodi.
In case of positivity of the transplant test carried out, it will be necessary to contact the Coordination
Nazionale Transplanti Operativo (CNTo) and the infectious disease second-opinion and the recipients will have to
be subjected to clinical and virological monitoring by means of a methodical search for DENV
molecular on a weekly basis for the first month post-transplant.
If the donors present symptoms compatible with a
Dengue virus infection (fever, headache, eye pain, muscle and joint pain,
nausea and vomiting, skin rash 3-4 days after the onset of fever) the test result for
the search for DENV must necessarily be available before organ harvesting. In case
of a positive result, the infectious disease second-opinion and the CNT Operational​

There was a previous cluster of autochtonous dengue in Italy in 2020, at the beginning of the pandemic, but the transmission chain was clear.
A woman returning from Djakarta, Indonesia, infected her household contacts during the home quarantine

Dengue, first autochthonous case this year in Italy. A 70-year-old from Lodi on the mend was hit

He reported no trips abroad. This means that the seventy-year-old who fell ill with dengue was infected at his home. The man lives in Castiglione d'Adda, in the province of Lodi. He was hospitalized in Crema, but he is better now.

His is the first case of native dengue (not imported with trips abroad) this year in Italy. The last indigenous cases of the tropical infection, caused by a virus transmitted by mosquitoes, dated back to 2020 in our country. At that time, the outbreak reached 11 cases, but without victims.

An ordinance was immediately issued by the Municipality against the mosquitoes of Castiglione d'Adda: it is forbidden to leave containers in which rainwater or stagnant water can be collected, both in public and private places. It is mandatory to keep the courtyards and open areas clear of weeds, brushwood and waste of all kinds. Even in the cemetery you can't immerse flowers in vases. Better to use damp sand instead of water, to dry up any possibility of insect incubation. Even blood donations among the citizens of the affected area are interrupted for a few days.​

Dengue, two other cases identified in Castiglione d'Adda

CASTIGLIONE D'ADDA - High guard in Lombardy on cases of Dengue. Two new cases of infection with the virus transmitted by Aedes mosquitoes (tiger mosquito) have been identified in Castiglione d'Adda. They concern a little girl, currently hospitalized in non-serious conditions at the Lodi hospital, and a sixty-year-old man, recovered and already back to work. Both reside not far from the first subject infected by the virus.

These are 3 cases of infection not linked to travel to countries where the disease is endemic and, considering the incubation time of the disease, it is to be assumed that they had a contemporary origin or in any case all arose before the disinfestation interventions. In this logic it is also possible to find subsequent further cases without them questioning the full effectiveness of the disinfestation intervention.

'In many cases the infection is asymptomatic - explained the regional councilor for Welfare, Guido Bertolaso ​​- so often the disease does not manifest itself and healing occurs spontaneously. To verify the possible exposure to the virus of other inhabitants of Castiglione d'Adda, we have therefore organized a further analysis: citizens, voluntarily and free of charge, will be able to go to the Codogno Community House to undergo a blood sample. The exam will make it possible to understand if you have come into contact with the virus through the analysis of the antibodies.​

Fourth case in Castiglione d'Adda

There are 104 citizens of Castiglione d'Adda (Lodi) who on Friday underwent screening for antibodies to Dengue, a virus transmitted by the Aedes mosquito (tiger mosquito) in the Codogno community house. This was announced by the Ats Metropolitan City of Milan (which also includes the Lodi area). The activity will also continue on Saturday 26 August, from 8 to 12, and Monday 28 August from 8 to 16.

Interested citizens of Castiglione d'Adda will be able to access the Community House and present themselves at the Single Access Point, asking to be screened for Dengue. An initial analysis of antibodies will be conducted and patients with a recent infection outcome will be offered an infectious disease visit and any diagnostic insights.

Also on Friday Ats Metropolitan City of Milan identified a new native positivity to Dengue. It is a person over eighty, residing in Castiglione d'Adda near the other 3 cases, who has already been hospitalized for days and is improving.​

Dengue fever positives rise to six

In Castiglione d'Adda these days it seems that we are talking about nothing else. Dengue fever continues to monopolize public debate. After the first days of screening carried out between last weekend and Monday, with 309 Castiglionesi who responded to the appeal launched by the Municipality and Ats to find out if they were affected by the virus brought by the bite of the Aedes mosquito, going to the clinic in Codogno or by booking a simple blood draw at home, the confirmed cases have risen to six, none in danger of life, someone practically asymptomatic (and only positive on the test) and someone else instead hospitalized. And there are those who find a possible explanation for the spread of the infection, which needs the tiger mosquito (or the rarer Aegypti from us) to pass from one man or one animal to another) in the large humid and marshy area of ​​the Adda Morta, like the opposition group 'Castiglione to be improved', which calls for monitoring of the insects present and the cocktail of viruses they contain. The epidemiological study by Ats will also try to clarify whether the endemic virus in the equatorial areas arrived in the country due to a person who has been abroad or if migratory birds 'imported' it instead. Mortality is very low but those who manifest the form of 'bone-breaking fever' are very ill and in countries where the circulation of Dengue is very high it also manifests itself with potentially fatal haemorrhages. So the health authorities aim to stop this new Third World souvenir of which there are already 5 different viral variants. This year West Nile, another disease transmitted by mosquitoes, is also hitting hard, with six people hospitalized in the Lodi area last week, while fortunately in Lombardy there is still no talk of Zyka, which causes very serious disabilities if it affects pregnant women to the unborn child.

Two other infected citizens were found: there are eight cases

There are 336 citizens of Castiglione d'Adda who have undergone screening for the search for antibodies to Dengue, a virus transmitted by the Aedes mosquito (tiger mosquito), at the Codogno Community House which remains open tomorrow, Saturday 2 September, from 9 to 13 and continues next week, from Monday 4 to Friday 8 September, from 8 to 10. For more information, consult the dedicated page on the ATS website.

«It is confirmed that the citizens of Castiglione d'Adda who want to participate in the screening but who cannot reach Codogno due to physical impediments can contact the Single Access Point (PUA) of the Community House by telephone on 0377/465352 and book the sampling at domicile» inform the Ats.

In addition, two other autochthonous Dengue cases were identified: the total figure is eight people, all with non-serious manifestations of the disease and residing in Castiglione d'Adda.​

Dengue, cases rise to 14 in the Lodi area

The cases of dengue, with or without symptoms, diagnosed this year in the province of Lodi rise to 14. The data comes from the Higher Institute of Health which indicates the total number of cases in Lombardy at 50 and 165 in Italy, of which it is believed that 19 were transmitted locally through the bite of mosquitoes which, after having drawn blood from an infected person, injected the virus in healthy individuals. The other cases are believed to have been contracted abroad by tourists who were bitten by Aedes mosquitoes (including Tiger) in countries where this fever is endemic, South America and the Far East. In 2023, in addition to Italy, outbreaks of indigenous dengue were reported in France. In past years, outbreaks of this type have been confirmed in several European countries including Croatia, France, Spain and Italy. It is estimated that every year 400 million people in the world contract dengue, which is fatal only in the rare cases of hemorrhagic form. In 80 percent of cases, dengue is asymptomatic. But it is much more dangerous to get infected multiple times. However, a sick person cannot infect other humans or animals unless he is bitten by an Aedes mosquito, which is the one with the white stripes.
