Investigators identified dozens of “medical tourists” from 17 states who contracted a rare and highly resistant strain of Pseudomonas aeruginosa while undergoing bariatric surgery in Tijuana, Mexico.

Of the 30 patients identified, almost half were hospitalized upon their return to the United States, although no secondary transmission at any U.S. hospitals has been reported, according to Ian Kracalik, PhD, MPHan Epidemic Intelligence Service (EIS) officer in the CDC’s Division of Healthcare Quality Promotion.
