Red vigilance has been announced in a majority of departments due to the proliferation of tiger mosquitoes.
What does the red vigilance announced in a majority of departments in the face of the proliferation of tiger mosquitoes mean?
Tiger mosquito: it can transmit certain diseases
“In fact, 67 departments are colored due to the presence of tiger mosquitoes, mosquitoes that are not from us, but imported, explains Isabelle Esteve-Moussion, vector control coordinator for the Occitanie Regional Health Agency. It has an important health characteristic: it can transmit certain diseases, such as dengue or chikungunya and zika.”
“Red by itself does not mean a high alert, she specifies. This simply means that in the department, these diseases could be transmitted in certain municipalities due to the presence of this mosquito. If it is not present, these diseases are not transmitted.”

All the departments of the region colonized
However, red vigilance is immediately worrying. What should be done concretely? “Recognizing it is not so obvious. Many mosquitoes are scratched, acknowledges Isabelle Esteve-Moussion, vector control coordinator for the Occitanie Regional Health Agency. But this one is really gray and white. A site is open to everyone: signalement-moustiques.anses.fr. Go on it if you think you have seen a mosquito in your home. Try to take a photo to report it.”
“If your town is not listed, we can advance knowledge of its colonization, she explains. All the departments of the region are colonized, but not all the communes are. When he is not carrying diseases, his bites are only mosquito bites. It overwinters in egg form, there is no transmission of viruses from adult to egg. It is therefore not necessarily loaded. The stock of mosquitoes appearing in this season will not be able to transmit because it will not have been contaminated.
