(AP)—At the main campus of the Centers for Disease Control and Prevention, dozens of people are working day and night to bring a meningitis outbreak under control.
Dr. John Jernigan is a medical epidemiologist at the CDC leading the clinical investigation team for the outbreak response. He says this infection, which is caused by a fungus, is very unusual.
Meningitis is typically caused by a virus or bacteria. The fungus linked to this outbreak is common in dirt and grasses, but it is making people sick because it found its way into a steroid injected into people with back pain.
That steroid was distributed by a Massachusetts pharmacy that is currently under investigation. Nearly 200 people in more than a dozen states have been sickened, including 15 who have died.
