Update on Fungal Meningitis Outbreak Following Surgical Procedures in Mexico

The CDC issued a Health Alert Network (HAN) Health Update to provide additional information on the outbreak of fungal meningitis among patients who underwent procedures under epidural anesthesia in Matamoros, Tamaulipas, Mexico. As of June 1, 2023, a multistate outbreak is ongoing among patients who underwent procedures under epidural anesthesia at two clinics: River Side Surgical Center and Clinica K-3. Three U.S. laboratories (CDC Mycotic Diseases Branch’s Laboratory, UCSF Clinical Microbiology Laboratory, and UW Medicine Molecular Microbiology laboratory) and the Mexican national laboratory (InDRE) have detected fungal signals consistent with the Fusarium solani species complex from the cerebrospinal fluid (CSF) of patients receiving follow-up care in Mexico or the United States. A total of 212 residents in 25 U.S. states and jurisdictions have been identified who might be at risk of fungal meningitis because they received epidural anesthesia at the clinics of interest in 2023. Among these patients, 14 suspected, 11 probable, and two confirmed U.S cases have been diagnosed and three patients (two probable cases and one confirmed case) have died.

Healthcare providers, public health officials, and the public should be aware that all patients, including those without symptoms, who underwent medical or surgical procedures under epidural anesthesia at River Side Surgical Center or Clinica K-3 in Matamoros, Mexico, since January 1, 2023, should be evaluated for fungal meningitis as soon as possible. Evaluation for fungal meningitis includes a lumbar puncture (LP, also known as spinal tap) and magnetic resonance imaging (MRI) of the brain.
