Health authorities in Mexico are trying to locate about 400 people who may have been infected with fungal meningitis. Of the 400 people sought, 20% are Americans and the rest Mexicans operated on at the River Side and K-3 Surgical Center clinics in Matamoros.
An American died in the context of the outbreak, which involves two medical centers in this town in the state of Tamaulipas (northeast), bordering the US Brownsville, in Texas. Meningitis causes inflammation of the membranes of the brain and spinal cord.
