TAMPA, Fla. (AP) - Gulf coast health officials are urging residents to use mosquito repellent after two people died of Eastern equine encephalitis this month.

On Thursday, Hillsborough County health officials elevated an advisory first issued in April to an alert to let residents know they need to be more cautious.

Officials say there were no human cases of any mosquito-borne illnesses in the county for the past two years.

No other human deaths from Eastern equine encephalitis have been
reported in Florida.

Four horses have died of Eastern equine encephalitis in Collier County this year.  There have been no human cases.
