Westchester County has its first positive human case of West Nile Virus this year.
Westchester’s Department of Health says the first case was confirmed in a 72-year-old Irvington resident who had been hospitalized, and is now recovering at home. The county Health Department says it found no signs of mosquito breeding activity around the resident’s home but treated surrounding catch basins with larvicide. West Nile Virus infection most often causes a mild or moderate flu-like illness, but can be more serious particularly for people 60 and older, and those with other health complications. Two batches of mosquitoes tested positive for West Nile Virus in Yonkers earlier in the summer, and were the season’s first positive batches.
