A mosquito-spread virus nicknamed "triple E" recently killed a resident of Ulster County, New York, marking the state's first human case reported since 2015. The case prompted health officials to declare the virus an "imminent threat to public health" and expand their efforts to protect New Yorkers from mosquito bites.
Earlier this year, triple E fatally infected a man in New Hampshire and also sickened several people in other Northeastern states. The Massachusetts town of Plymouth began closing its public parks between dusk and dawn to help cut the risk of people catching the infection.
