OCALA, Fla. -- The Florida Department of Health has diagnosed two more people with meningitis stemming from tainted vials of a steroid injection.

State officials said in a news release Friday that a 52-year-old woman and a 79-year-old woman contracted meningitis. Both were treated at the Marion County Pain Management Center with the steroid.

There have been nine cases of meningitis in Florida so far, including two deaths. The contaminated steroid has led to a multi-state meningitis outbreak.

Federal health officials have tracked down 12,000 of the roughly 14,000 people who may have received contaminated steroid shots in the nation's growing meningitis outbreak. Officials warn that patients will need to keep watch for symptoms of the deadly infection for months.
