Dengue, chikungunya: where did we in France?

After ultramarine, the metropolis is in turn affected by dengue and chikungunya, two diseases transmitted by the tiger mosquito. The Health Watch Institute reported on reported cases in 2014. And to encourage alertness.

Between 1 May and 30 November 2014, activity period of the tiger mosquito, 454 cases of chikungunya and 167 cases of dengue were reported in the metropolitan area. Most involved people who have traveled to areas affected by epidemics. But "native" cases have also appeared. These are people who have not stayed in those risk areas that have been contaminated in the south of France. Thus, four cases of dengue were detected in region Provence-Alpes-Côte d'Azur and 11 cases of chikungunya were confirmed in Montpellier, in the course of 2014.

The tiger mosquito, vector of these diseases, appeared in France for the first time in 2004. He has since been spotted in 18 departments.

In Greater Montpellier, chikungunya outbreak developed in October 2014, from an infected patient in Cameroon. The virus then spread via mosquitoes in an area of ​​small buildings and pavilions, with many gardens, and a fairly dense population.

Regarding dengue, two people have been affected in the Var and the other two in Aubagne in the Bouches du Rhône, in August and September 2014.

All these patients are cured now, but some have kept the legacy, especially joint pain.

Each time, steps have been taken to avoid the risk of epidemics: a survey door-to-door in a radius of 200 meters around the patient's home to identify other cases, the application of anti products mosquitoes, removing pools of water up larvae.

This anti-spread plan seems effective since the number of cases has been limited. But in the editorial of the latest weekly epidemiological bulletin published by the Health Watch Institute, the epidemiologist Jean-Claude Desenclos questions. How, in future, to reduce the tiger mosquito? How that prevent other viruses, such as Zika, landed in France? How to raise awareness of this emerging risk?
