Two different types of mosquitoes – one that carries West Nile Virus and another that can spread dengue and yellow fever have Fresno County health officials on high alert.
The county says a crow reported earlier this month tested positive for West Nile Virus. Officials have also detected the presence of another invasive mosquito species that can spread potentially serious tropical diseases. In severe cases, the more serious symptoms stemming from these diseases can lead to death.
David Luchini is the assistant director for the county’s Department of Public Health.
