What is it? dengue fever

Dengue, also known as "tropical flu," is a viral disease transmitted to humans by mosquitoes of the genus Aedes, also known as tiger mosquitoes.

The dengue virus has four strains distinct? An individual is likely to be infected with each of the four strains during his lifetime

Symptoms

Dengue fever occurs after 2 to 7 days of incubation with the appearance of a high fever often accompanied by headache, nausea, vomiting, joint and muscle pain and a rash that resembles that of measles.

After 3 to 4 days, a brief remission is observed, followed by symptoms. Intensified – conjunctival haemorrhages, nose bleeds or bruising may occur – before regressing rapidly after one week

The recovery is accompanied by a recovery of fifteen days. Clbadical dengue, although highly debilitating, is not considered a severe disease such as dengue haemorrhagic fever.

Two serious forms of dengue fever

Although it is not known why, in some patients Dengue fever can take two serious forms: dengue haemorrhagic fever and dengue fever with fatal shock syndrome

The haemorrhagic form of the disease, which accounts for about 1% of dengue cases worldwide, is extremely severe: fever persists and multiple haemorrhages, including gastrointestinal, cutaneous and cerebral, often occur.

In children under fifteen years in particular, a state of hypovolemic shock can however settle (cooling, wetness of the skin and imperceptible pulse signaling circulatory failure), abdominal pain, and, without infusion, causing death.

Dengue sets in Europe

Initially present in the tropical and subtropical zones of the world, dengue has now reached Europe where the first 2 indigenous cases were recorded in 2010.

In 2014, the mosquito vector is implanted in 18 French departments. The risk of spread will be real if infected people arrive in metropolitan France.

An application of insecticide

Even though no case of "autochthonous" dengue fever has been reported in metropolitan France, the Atlantic EID has carried out a spreading operation in Ambès, France. district where the patient resides, to avoid any risk of contamination.

This application of deltamethrin, an insecticide molecule, on the night of Monday to Tuesday. This molecule is toxic if it is inhaled or ingested.

The inhabitants of the town had therefore been instructed to "close the windows", "to move their animals away" and especially "not to consume the fruits and vegetables of [leur] garden for at least two days. "

Angry mayor of Ambes

The mayor of Ambes let out his anger over this situation still Southwest . Kevin Subrenat, who recalls that several municipalities and inhabitants of the region were refused the application "anti-larval biological" they claimed.

"I wonder why the County Council, the Prefecture, the ARS and DDTM opt for a cure and highly toxic in the urban area rather than a biological preventive treatment in the marshes, "he said in a statement.

Reunion faced with a strong dengue epidemic [19659006] The dengue epidemic continues at a high level in Reunion, despite the arrival in June of the southern winter, a season unfavorable to mosquitoes.

The prefect of Reunion and triggered, Tuesday, July 10, level 4 of the device which implies a strengthening of the mobilization and prevention against the mosquito vector of the disease

The pbadage to level 4, the last before the "mbad epidemic", provides for the activation of the diet Adapted military service (RSMA) in support of vector control activities

More aid-badisted contracts "Parcours emploi compétence" (PEC), 80-90% of which are financed by the State, will also be awarded to badociations specialized in the cleaning of public space

Communication and information actions for doctors, laboratories and the public will be strengthened. Repellents will also be distributed to target audiences.

From the beginning of the year to July 10, 5,970 cases of biologically confirmed dengue fever have been identified. One hundred and twenty-four patients had to be hospitalized. These figures would fall short of the reality.

Risk of an "epidemic explosion" next summer

"There is also an increasing dispersion of the number of cases on the island, particularly in the north and south, "says Marie-Amélie Vauthier-Bardinet, cabinet director of the Prefect of Reunion.

Maintaining a circulation of the virus during the winter poses the risk of an" epidemic explosion during The idea is to take advantage of the cold season to eradicate the virus, "she adds.

If this goal is not achieved, as soon as the warm season comes back the risk would be to have to deal with a major epidemic, as was the case with chikungunya in 2005-2006. More than 260,000 people, one-third of the population, had been infected. Two hundred and twenty-five people died of the disease

The second risk is the development of an "endemic" dengue fever. "The virus would continue to circulate and come back every year," said Dr. François Chieze, director of the health watch and safety unit at the regional health agency.
