All passengers diagnosed with life-threatening bacteria, Pseudomonas aeruginosa or CRPA, who are resistant to life, were invasive medical procedures. The most common procedure was the weight loss operation. The Agency did not indicate when the operations were performed or how many patients were infected.
"The infections caused by this specific drug-resistant Pseudomonas are rare in the United States and are difficult to treat," they said in the CDC. Patients usually require long and "complex antibacterial combinations of drugs and courses" to prevent infection.
Almost half of the infected patients were operated at the Grand View Hospital in Tijuana; others were operated in other hospitals and clinics in the area.
The CDC says the Mexican government has closed Grand View Hospital "until further notice", but the agency still states that there are no operations there until the authorities confirm that drug-resistant bacteria are no longer present.
According to the latest survey, about 72% of patients using medical tourism traveled to cancer, spine and other orthopedic surgeries, followed by cosmetic and plastic surgery, and cardiovascular and neurosurgery.
More than 50% of operations cost between 10,000 and 50,000 USD, and 16% between 50,000 and 100,000 US dollars, the survey showed.
There are high risks when traveling abroad for treatment, CDC warns.
"Resistance to antibiotics is a global problem, and resistant bacteria can be more common in other countries than in the United States," the agency said.
