The infections are linked to the usage of an epidural anesthesia at two clinics in Matamoros — River Side Surgical Center and Clinica K3. The clinics were shut down in May when the outbreak was initially reported. Mexico's Ministry of Health is investigating the clinics.

The CDC is still warning U.S. residents to avoid getting surgery in Mexico because they don't know what happened.
