Health officials have confirmed two cases of West Nile Virus in Queens, New York City, with one patient hospitalized due to a brain infection and another receiving treatment. Additional possible cases are under review in Brooklyn. The virus has also been detected in mosquitoes across all five boroughs of New York City, prompting warnings especially for older adults and individuals with weakened immune systems to take precautions against mosquito bites. In Brooklyn and Staten Island, infected blood donations have been flagged. Meanwhile, in Naperville, Illinois, mosquitoes have tested positive for West Nile Virus, leading city authorities to urge residents to exercise caution and implement preventive measures. These developments coincide with broader concerns about the spread of mosquito-borne illnesses such as West Nile Virus and Eastern Equine Encephalitis (EEE) in northern U.S. states. Local health departments emphasize the importance of personal protection and vector control programs to reduce transmission risks.
