A Plymouth County man in his 70s has become the first person in the state this year to be diagnosed with West Nile virus. The man was hospitalized but is recovering, the Department of Public Health announced Monday.
It is high season for the mosquito-borne disease, which can cause fever and flulike symptoms. While the virus poses the highest risk to people over age 50, most infected with West Nile will have no symptoms.
Last year, 33 people were diagnosed with the disease, starting in mid-August, and one man died.
West Nile is the less dangerous of two viruses transmitted by mosquitoes that are now an unfortunate marker of summer’s end. The state announced last week that a Norfolk County woman in her 80s died of Eastern equine encephalitis.
