The Florida Department of Health announced an additional human case of West Nile virus (WNV) infection reported this week in Palm Beach County.
This bringing the total WNV cases to 18– 13 in Miami-Dade County, three in Palm Beach County, and two in Broward County.
In addition, thirty-one asymptomatic positive blood donors have been reported in 2020 from Miami-Dade County.
West Nile virus (WNV) is the leading cause of mosquito-borne disease in the continental United States. It is most commonly spread to people by the bite of an infected mosquito. There are no vaccines to prevent or medications to treat WNV infections in people.
Most people infected with West Nile virus do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms such as headache, pain, and fatigue. People with mild illness typically recover within about a week with symptomatic treatment. Less than one-percent of infected people develop a serious, sometimes fatal, illness.
Symptoms typically appear between two and 14 days after the bite of an infected mosquito. People over the age of 60 and individuals with weakened immune systems are at an increased risk for severe disease.
