Culex mosquitoes identified as West Nile virus vectors

The Culex mosquito genus is identified as the primary vector for transmitting the West Nile virus to humans and animals. These mosquitoes typically become infected after biting infected birds and can subsequently spread the virus through subsequent bites.

Culex mosquitoes are most active from dusk until the early morning hours, though their behavior is also influenced by temperature and weather conditions. They breed in stagnant water, including small amounts found in flowerpots, saucers, buckets, and manholes.

Health experts, including Professor Vasilakopoulos, recommend several preventative measures: removing standing water near residences, using mosquito nets and window screens, applying approved insect repellents, and wearing long-sleeved clothing during peak activity periods. Using a fan can also help deter mosquitoes.

Regarding symptoms, approximately 80% of infected individuals show no symptoms, while about 20% experience mild illness, such as fever. Less than 1% of cases develop severe disease.
