A man in his 40s likely contracted West Nile in Middlesex County, state officials said, and a woman in her 70s is the out-of-state case. Eight human cases were confirmed in 2022.
Health officials said no birds or humans have tested positive for the virus in Barnstable so far this year.
WNV was initially found in mosquitoes in Massachusetts in 2000 and primarily affects birds.
WNV is most commonly transmitted to humans by the bite of an infected mosquito. The mosquitoes that carry this virus are common throughout the state, and are found in urban as well as more rural areas.
While WNV can infect people of all ages, people over the age of 50 are at higher risk for severe infection.
