NASHVILLE (AP) - Tennessee health officials have identified two more patients who contracted meningitis after getting steroid injections for back pain at a Nashville clinic.

That raises the number of people who developed fungal meningitis after the injections to 14. One was in North Carolina and the rest are in the Nashville area. Two patients have died.

Dr. David Reagan, chief medical officer for the Tennessee Department of Health, said Tuesday that officials are now classifying the incidents as an outbreak of meningitis.

Health officials said it's still too early to determine the source of the infection; however, three lots of injectable steroid used at the St. Thomas Outpatient Neurosurgery Center have been recalled by the manufacturer.

Officials haven't identified the drug manufacturer or the city in North Carolina.
