The CDC and Texas state health officials are warning Americans to avoid any cross border medical tourism trips to Mexico.
Five people from Texas returned to the US with suspected cases of fungal meningitis.
One of them later died.
They had all traveled across the border to Matamoros for medical treatment.
The four others, aged from 30 to 50 years old, remain in hospital.
The CDC issued a travel advisory urging people not to go to Matamoros for medical tourism.
Meningitis causes swelling of the the brain and spinal cord and requires urgent medical attention.
Symptoms include fever, headache, nausea, and vomiting.
“It is very important that people who have recently had medical procedures in Mexico monitor themselves for symptoms,” Texas health department commissioner Dr. Jennifer Shuford said.
“Meningitis can be a life-threatening illness.”
