Hartford & New Haven, CT, August 3, 2026 —
Branford, CT – Mosquitoes collected in Branford, Connecticut, have tested positive for the West Nile Virus (WNV), state health officials confirmed. The affected area is specifically noted as the Hosley Avenue vicinity.
While this detection marks the first WNV-positive mosquito pool identified in Connecticut for the summer season, state health authorities emphasized that no human cases of the virus have been reported in Connecticut thus far this year. Nonetheless, the presence of the virus in the mosquito population is prompting advisories for residents.
The Connecticut Department of Public Health (DPH) and local health officials are urging residents to take precautions to prevent mosquito bites, as mosquitoes are the primary vectors for transmitting West Nile Virus to humans and animals.
Recommended protective measures include:
- Using insect repellent: Applying EPA-registered insect repellents containing DEET, picaridin, oil of lemon eucalyptus, or other effective ingredients when outdoors.
- Wearing protective clothing: Covering arms and legs with long-sleeved shirts and pants, particularly during dawn and dusk when mosquitoes are most active.
- Mosquito-proofing homes: Ensuring that window and door screens are in good repair to prevent mosquitoes from entering residences.
- Reducing mosquito breeding sites: Eliminating standing water around homes, such as in bird baths, clogged gutters, and old tires, where mosquitoes can lay their eggs.
West Nile Virus is typically spread to humans through the bite of an infected mosquito. Most people infected with WNV do not develop any symptoms. However, a small percentage can experience more severe illness, including neurological disease, which can be fatal in rare cases. Symptoms, when they occur, can include fever, headache, body aches, vomiting, diarrhea, or rash. In severe cases, individuals may experience encephalitis (inflammation of the brain) or meningitis (inflammation of the membranes surrounding the brain and spinal cord).
Health officials will continue to monitor mosquito populations for WNV activity throughout the state. Further information and updates on West Nile Virus can be found on the Connecticut Department of Public Health website.
