In a follow-up on the fungal infections following surgical procedures in Matamoros, Mexico, as of June 1, 2023, the multistate outbreak of fungal meningitis 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 (U.S. 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; three patients (two probable cases and one confirmed case) have died.
According to the Texas Department of State Health Services (DSHS), 149 people are under investigation (People who got surgery in Matamoros in 2023 but have no known symptoms), seven suspected cases, 10 probable cases and one confirmed case in Texas residents have been reported.
In addition, DSHS reports three Texas residents who were part of the outbreak have died as a result of their illnesses.
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.
