This Wednesday, June 15 and Thursday, June 16, the presence of tiger mosquitoes in the arena area will be closely monitored before, if necessary, a mosquito repellent treatment. “The risk of contamination is quite low,” according to the ARS.
An imported case of dengue has just been identified in Nîmes. As required by the procedure in such a circumstance, the Regional Health Agency (ARS) conducted an “epidemiological investigation” of the patient. “The aim was to find out, during the period of viremia (presence of virus in the blood, ed.), Where the person has been, for how long, and who he has been with,” said the ARS departmental delegate. Claude Rols.
An adult nocturnal treatment is possible
A step that triggered a second survey, this entomological one, underway this Wednesday and this Thursday and conducted by the vector control operator Altopictus, mandated by the Regional Health Agency. He will intervene in the city center, in the immediate vicinity of the arenas, to look for the presence, or not, of the tiger mosquito (Aedes albopictus)dengue vector.
If this survey proves positive, adult nightly treatment will be provided in the area in the coming days. It is made from a vehicle (pick-up type) and a full potential for pedestrian treatment. The insecticide used (Aqua-K Othrine, based on deltamethrin to be precise) is allowed by regulations. The Gardois beekeepers’ union has already been informed of its possible use because it may threaten the survival of bees; although in the present case, in the heart of the city, the impact on the matter would probably be limited.
“Cutting Transmission Chains”
“Every year we are faced with cases of imported dengue, even if it is still quite rare,” continues Claude Rols. that the persons concerned be accompanied. In this case, the risk of contamination is quite low. “
In recent years, the Gard, Nîmes in particular, had experienced two small “clusters” of dengue, in the hills and at the Mas de Ville, where there are about fifteen indigenous cases (with contamination on the spot, and not reported in Metropolitan France) had been registered. Scenario that the government wants to avoid.
