The tiger mosquito has been established and active for several years in all the departments of the Occitanie region. Each year, a reinforced surveillance system is implemented by the health authorities and their partners from May 1 to November 30. During this period of activity of tiger mosquitoes in metropolitan France, the objective is both to limit their proliferation and to prevent the risk of transmission of viruses of which they can be the vector (chikungunya, dengue or zika).
Fighting the tiger mosquito means first of all preventing it from developing at home
The enhanced surveillance system is based on:
- Reinforced surveillance of mosquito populations (entomological surveillance).
- Raising awareness among people living in areas where these mosquitoes are present and active.
Controlling these mosquitoes and their larvae is one of the main ways to prevent the transmission of viruses. It is a reflex to acquire at home to protect yourself collectively.
The enhanced surveillance system also involves:
- Reinforced medical surveillance of human cases of the diseases that this mosquito can carry:
chikungunya, dengue and Zika (epidemiological surveillance). This surveillance mobilizes health professionals from across the region to immediately report to the Regional Health Agency any case of a patient showing symptoms of dengue, chikungunya or Zika.
Transmission of the virus comparable to previous years despite health measures
In Occitania in 2020,
• 128 cases of imported arboviruses (travelers) were reported.
• 3 indigenous cases of dengue reported in Gard and Hérault (People who contracted the disease without having traveled to a contaminated area).
• These reports gave rise to 172 inquiries / surveys around the places frequented by the cases.
• 125 treatments around places frequented by infected people where the presence of the tiger mosquito was confirmed.
Despite the confinement restrictions, this year is comparable to the previous year in terms of contamination. The departments with the most interventions are: Le Gard, Haute Garonne and Hérault
- 123 surveys and 105 treatments;
In Occitania 1,480 municipalities out of the 4,454 municipalities in the region (33%) are colonized, which represents 83% of the regional population, or nearly 5 million inhabitants.
