Tiger Mosquito Eggs Found in Rennes: Two Neighborhoods on Alert

What: The⁢ Asian tiger mosquito (aedes albopictus) remains active in France later than usual, with eggs‌ found‍ even in October.
Where: Primarily reported in the Brittany region (Rennes ‍specifically), but the species is established in numerous departments across France.
When: Typically active ‌from May to‌ November, but 2023 shows continued activity into late October/possibly November. Eggs have been found in⁤ Rennes in October 2023.
Why it Matters: ⁤ The tiger mosquito is an ⁣invasive species and a ⁢vector for diseases⁢ like dengue ⁢fever, chikungunya, and zika virus. Prolonged activity ⁢increases the risk ‌of transmission,even if cases are currently ‌rare in⁣ France.
What’s Next: Continued monitoring for mosquito presence and ⁣egg-laying. Public health authorities are urging vigilance and preventative measures (removing standing water). The length ⁤of the season will depend on weather conditions.
