Equip yourself, if possible, with mosquito nets and repellents. These are the caution instructions sent, in the middle of last week, to some of the inhabitants of Sceaux and Bourg-la-Reine (Hauts-de-Seine). A sector where the regional health agency (ARS) supervised, on the night of Friday September 9 to Saturday September 10, a vast mosquito control operation aimed in particular at suppressing the proliferation of the tiger mosquitootherwise called Aedes Albopictus, and thus limit the risks of possible transmission of the dengue virus.
