Florida reports 4th West Nile virus case, this one in Volusia County

For the fourth time this year, Florida health officials are reporting a human West Nile virus (WNV) case.

On Friday, the Florida Department of Health in Volusia County (DOH-Volusia) confirmed a case of WNV infection.

While none of the county’s sentinel chickens have tested positive for antibodies to the virus, this single case increases the concern for transmission to humans. Sentinel chickens are used to detect some mosquito-borne illnesses, such as West Nile virus. The birds do not develop disease symptoms but will test positive to antibodies if infected.

Volusia County Mosquito Control and DOH-Volusia continue surveillance and prevention efforts.

Earlier this year, human WNV cases were reported in Escambia County (October), Santa Rosa County (September) and Taylor County (October). In addition, one asymptomatic positive blood donor was reported from Escambia County (August).

DOH-Volusia recommends that residents and visitors should avoid being bitten by mosquitoes by taking basic precautions to help to limit exposure, including:

DRAIN standing water to stop mosquitoes from multiplying.

COVER skin with clothing or repellent.
