Hillsborough and Hernando counties are reporting their first swine flu deaths.
In Hillsborough, two adult males died. The men, ages 44 and 49, had underlying medical conditions that put them at greater risk for complications, according to the Hillsborough County Health Department.
In Hernando, confirmation of the death of a 40-year-old man came Thursday morning from the county health department.
"This is very sad news to report. Our sympathies go out to the family and friends of this individual," said Elizabeth Callaghan, administrator of the Hernando Health Department.
Hernando officials said it was uncertain if the victim, whom they did not identify, had underlying health conditions.
Hernando County has had three confirmed cases of the H1N1 virus to date. Hillsborough County currently has about 140 confirmed cases. There have been 25 deaths associated with the virus in Florida, according to the Hillsborough health department.
