If the Department of Health's epidemiologist determines there is an outbreak or the potential for an outbreak, a mosquito-control program would be initiated. Adult mosquitoes carrying the virus would be controlled through localized pesticide spraying. The departments of Health and Agriculture will perform laboratory testing to determine the presence of the virus in the specimens from mosquitoes, birds, animals and humans. We're continuing to work with veterinarians and horse owners across the state to monitor horse populations. West Nile virus previously only was found in Africa, Eastern Europe and West Asia.
Mosquitoes acquire the virus from infected birds and horses.
Those mosquitoes then transmit the virus to people and other animals. The virus, when transmitted to people, can cause West Nile encephalitis, an infection that can cause an inflammation of the brain. Anyone can get the virus, but older adults and people with compromised immune systems have the highest risk of developing severe illness because their bodies have a harder time fighting off disease. West Nile virus cases occur primarily in the late summer or early fall, although mosquito season is usually April to October. The funds would provide necessary staffing and epidemiological infrastructure.
