“Go dwelling and shut your home windows“,”herald laundry and kids’s toys“,”maintain pets away“,”wait three days earlier than consuming fruit and greens out of your backyard“: a nuclear assault could possibly be advised within the directions to the inhabitants… That is, nevertheless, solely a mosquito management operation, which the residents of rue du Chalet (eighth) have been knowledgeable about lately, by way of posters and letters of their containers publish.
Not a Russian strike as such, however a catastrophe all the identical: theAedes albopictusthe tiger mosquito, which is on the assault this summer season in France, and has the power to hold viruses of tropical ailments: dengue, zika and chikungunya.
The danger of an epidemic can be much more vital as a result of the Olympic Video games will convey 1000’s of international guests to France from nations the place these ailments are on the rise.
2000 circumstances of dengue fever imported because the starting of the 12 months in France, together with 64 in Paca
Since January, 2,000 imported dengue circumstances have already been reported in France, in comparison with 131 in 2023.
“In Paca, we’re at 64 imported circumstances” signifies the Regional Well being Company, which recollects that, final 12 months, 4 outbreaks of indigenous circumstances had been recorded, which resulted in 17 sufferers being contaminated in France by an contaminated mosquito.
That’s the reason, for each confirmed case of dengue, chikungunya or zika, a focused mosquito management operation is organized within the affected person’s residing space.
Thus, in rue du Chalet, as in different areas of Marseille, insecticide spraying was determined after a case of imported dengue fever was reported. A mission entrusted to theInterdepartmental settlement on mosquito management (EID), which usually proceeds at evening to restrict inhabitants publicity to the sprayed product and to guard wildlife and pollinating bugs.
“Well being dangers (deltamethrin, Bti) will not be related to the merchandise used on the doses and utility strategies used.“, declares ARS Paca, which, nevertheless, recommends fastidiously observing the directions issued.
However then why not generalize these mosquito management measures as some mayors are demanding? In our area, the place the tiger mosquito colonizes greater than half of the municipalities, 97% of the inhabitants could possibly be uncovered to a contaminated chew!
Capable of multiply by 200 each 15 days
“We should keep away from the event of resistance in tiger mosquitoes towards pesticides“, responds the ARS. In actual fact, evaluation confirmed the looks of resistance genes to the merchandise used among the many populations current in Paca.
“This case is of nice concern as a result of, if these genes are extensively transmitted amongst tiger mosquito populations, we’ll not have efficient pesticides to forestall contaminated larvae and adults round native circumstances..”
Many contaminated mosquitoes might hit and contaminate the inhabitants significantly, and create an epidemic in our area…
As well as, mosquito management utilizing insecticide just isn’t a panacea: 10 days after spraying, mosquitoes can recolonize an space. And theAedes albopictus it may be multiplied by 200 each 15 days….
“Citizen mobilization”
The one everlasting resolution to this scourge is the destruction of larval breeding websites. “Just a few millimeters of water is sufficient for the feminine mosquito to arrange her nest. Eradicating this chance through the use of flower cups, water collectors, residual watering, even a easy flip cap would clear up 80% of the issue.“, argues entomologist Frédéric Simard.
All residents are requested to take “saving gestures” this summer season: “One journey to your terrace or backyard per week is sufficient for defense”. The ARS asks “citizen mobilization“.
