WEST PALM BEACH, Fla. – Health officials in Palm Beach County on Monday announced a human case of West Nile virus that was acquired locally.
The case was detected last week after the victim donated blood, which tested positive for West Nile antibodies.
The Florida Department of Health advised residents that there has been a recent increase in mosquito-borne disease activity in areas of Palm Beach County.
Experts said there is a “high concern” that additional residents may be sick from the West Nile.
The Palm Beach County Mosquito Control and Health Department said they continue surveillance and prevention efforts to reduce mosquito-borne diseases.
“We looked for mosquito larvae, and they treated many different areas and roadside swells that were outclassing mosquitoes. In addition, we are outfitting ULV, ultra-low volume spray trucks to spray for adult mosquitoes, ”said Chris Risinger of Palm Beach County Mosquito Control.
According to health experts, most West Nile virus infections, about 80 percent, are asymptomatic. Those who develop symptoms usually experience headaches, fever, pain, and fatigue.
The best way to avoid mosquito bites is to wear long sleeves, light colors, insect repellent or stay indoors.
The last human cases of West Nile virus in Palm Beach County were two in 2018, although both were imported cases.
