In addition to typical meningitis symptoms like headache, fever, nausea and stiffness of the neck, people with fungal meningitis may also experience confusion, dizziness and discomfort from bright lights. Patients might just have one or two of these symptoms, the CDC says.
Health officials say any patients who received an injection at one of the facilities beginning July 1 and who began showing symptoms between one and three weeks after being injected should see their doctor right away.
The earlier a patient gets treatment, the more likely he or she will survive.
Patients are treated with anti-fungal medication, which is given intravenously, so patients have to be admitted to the hospital, the CDC said. Patients may need to be treated for months.
The FDA is urging anyone who has experienced problems following an injection with the NECC product to report it to MedWatch, the FDA's voluntary reporting program, by phone at 1-800-FDA-1088 or online at www.fda.gov/medwatch/report.htm.
