Massachusetts health officials are reporting the state's first human case of West Nile Virus this year.
The patient is described only as a man in his 60s who lives in Middlesex County. Officials say the man remains hospitalized, but is recovering.
The Department of Public Health said in a statement on Friday that the diagnosis of West Nile was confirmed by testing at the Hinton state lab in Boston.
Officials say they are trying to determine when the man was most likely to have been exposed to mosquitoes infected with the virus.
There were eight confirmed cases of West Nile among Massachusetts residents last year, none of them fatal.
Symptoms can include fever or flu-like illnesses.
