The Centers for Disease Control and Prevention confirmed Wednesday that 15 Hoosiers have been infected.
The New England Compounding Center (NECC), the Massachusetts-based pharmacy that made the contaminated injections, voluntarily recalled three lots of the injected steroid last week.
Health officials say 76 medical facilities in 23 states received the contaminated steroid injections from NECC. A list of the 76 affected medical facilities is on the CDC's website.
The number of meningitis cases could reach up to 13,000 patients.
