New York City health officials have confirmed the first human cases of West Nile virus this season. Two residents of Queens tested positive; one was discharged after a brief hospitalization, while the other is being treated for encephalitis, a serious brain infection, Gothamist reported.
The Health Department also detected the virus in blood donations from a Brooklyn resident and a Staten Island resident. However, these cases did not meet the criteria to be classified as official infections, according to a department spokesperson. Additional potential cases in Brooklyn are under investigation, with updates expected within the next two weeks.
Mosquito season in New York City runs from May through October, peaking in August and September. ABC7NY reported that the Health Department conducts regular spraying in neighborhoods to reduce mosquito populations and limit the spread of the virus.
Acting Health Commissioner Dr. Michelle Morse stated that the risk of serious illness is higher for people over 55 and those with weakened immune systems, Gothamist reported. Preventive measures include using insect repellent, maintaining window screens, and removing standing water.
Most people infected with West Nile virus show no symptoms, but some may develop fever, headaches, or muscle aches. Health officials advise seeking medical care if infection is suspected.
