NAPLES (AP) – Three Collier County Jail inmates have tested positive for swine flu.

The inmates are being treated under medical isolation. Four other inmates are also being treated with flu-like symptoms.

The jail is making sure steps are taken to reduce the likelihood of additional cases by sanitizing all the areas where the infected inmates came into contact with and staff there are being reminded to wash their hands.

Last week, the Florida Department of Health reported a total of 2,915 confirmed cases of swine flu. Another 22 residents infected with the virus have died.
