One case of West Nile virus infection has been confirmed in Volusia County, according to the Florida Department of Health in Volusia County.
Authorities say none of the county’s sentinel chickens have tested positive for antibodies to the virus.
However, they note the 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 for antibodies if infected.
Volusia County Mosquito Control and Volusia health department officials say they will continue surveillance and prevention efforts.
They note that residents and visitors should take steps to avoid being bitten by mosquitoes.
Those steps include draining areas of standing water, such as garbage cans, gutters, buckets and coolers.
People are advised to keep their skin covered with long sleeved clothing, or wear repellent
Repellents with DEET, picaridin, oil of lemon eucalyptus, and para-menthane-diol, are effective.
Officials advise using mosquito netting to protect children younger than 2 months old.
