Health officials say a 64-year-old man has been diagnosed with West Nile virus.
The Alachua County Health Department confirmed Tuesday that he's the first person in the Gainesville area to be diagnosed with the mosquito-borne illness this year.
Officials say the man started having symptoms in mid-September.
The Gainesville Sun reports the man had not traveled in the two weeks before the symptoms started so health officials believe he contracted in the county.
Health department administrator Paul Myers says the case is serious, but he didn't comment on the man's current condition or where he is being treated.
People with West Nile experience fever, headache or body aches. It can also cause seizures or paralysis.
Officials say three cases of West Nile have been reported in Florida this year.
