JACKSONVILLE, Fla. – Duval County health officials have confirmed a second locally acquired case of West Nile virus, prompting additional mosquito surveillance and spraying efforts in the Jacksonville area.
The Florida Department of Health in Duval County announced the case as it works with Jacksonville Mosquito Control on prevention efforts. Ground spraying is being conducted as part of the response.
Health officials did not release information about the patient, including the person’s age, condition or where in Duval County the infection is believed to have occurred.
West Nile virus is transmitted to people through the bite of an infected mosquito. It does not spread from person to person.
Many people infected with the virus do not become sick. Those who develop symptoms can experience fever, headache, body aches, weakness, rash, nausea, vomiting or diarrhea, according to DOH-Duval.
More serious symptoms can include neck stiffness, changes in mental status and disorientation. Symptoms can develop between two and 14 days after a bite from an infected mosquito.
With a second locally acquired case now confirmed, health officials are urging residents to take precautions against mosquito bites, including reducing exposure to mosquitoes and following prevention measures recommended by the Florida Department of Health.
The state also continues surveillance for other mosquito-borne illnesses, including Eastern equine encephalitis, St. Louis encephalitis, malaria, chikungunya and dengue.
Florida residents are encouraged to report dead birds to the Florida Fish and Wildlife Conservation Commission because reports can assist officials with monitoring mosquito-borne diseases.
Duval County residents experiencing symptoms or seeking additional information can contact DOH-Duval at 904-253-1850.
