Infection Risk and Medical Travel in Latin America: What the CDC Has Documented and How to Lower Your Risk

When patients worry about surgery abroad, they often think about the surgeon's skill or the anesthesia. Infection gets less attention, yet it is the problem most often reported after medical travel. This article explains what U.S. public health authorities have documented, why infections after treatment abroad can be harder to manage, and practical steps that lower your risk wherever in Latin America you choose to go.

What the CDC Says

The CDC Yellow Book (2026) identifies infections as the most common complications of medical tourism. It lists several types:

• Surgical site infections, where the wound or tissue around it becomes infected.
• Bloodstream infections.
• Infections passed on through donated organs or tissue.
• Blood-borne infections such as hepatitis B, hepatitis C and HIV, which the CDC links to inadequate infection control.

Documented outbreaks in the region

The same CDC chapter describes outbreaks among medical tourists, including:

• Fungal meningitis after epidural anesthesia in Mexico.
• Carbapenem-resistant Enterobacterales (CRE), a group of drug-resistant bacteria, after invasive procedures in Mexico.
• Nontuberculous mycobacteria infections of surgical sites after cosmetic surgery in the Dominican Republic.

These outbreaks are useful to understand not because they define those countries, but because they show the specific failure points: anesthesia procedures, invasive procedures with poor sterilization, and cosmetic surgery in facilities with weak infection control. Those risks exist anywhere standards slip, including at home.

Drug-resistant organisms

The CDC notes that some resistant bacteria and fungi, including CRE and Candida auris, may be more common in some destination countries. An infection caused by a resistant organism can be harder to treat, and doctors at home may need to know where you were treated to choose the right antibiotics.

Why Infections After Travel Are Harder to Manage

An infection that appears a week after you fly home lands in a gap between two care teams. The surgeon who operated is thousands of kilometers away. The doctor in front of you did not do the operation, may not have the operative notes, and may not know which antibiotics you already received. That gap can delay the right treatment.

The CDC advises U.S. clinicians to take an explicit travel history, including care received abroad, and to screen for CRE in patients who had an overnight stay in a health facility outside the United States within 6 months. It also asks clinicians to report infections linked to medical tourism to public health authorities. All of that depends on you telling your doctor about your trip.

Choosing a Facility With Infection Control in Mind

You cannot inspect an operating room yourself, but you can ask questions that reveal how seriously a facility takes infection prevention.

Questions to ask

1. Where exactly will the procedure be performed: a hospital, a licensed surgical center or a clinic office?
2. Is the facility licensed by the national health authority, and is it accredited by a national or international body?
3. Who is responsible for infection control at the facility?
4. How are instruments sterilized, and are single-use items used once?
5. What is the plan if I develop an infection while I am still in the country?
6. Which hospital would I be transferred to if I needed intensive treatment?

Accreditation is a useful signal. The CDC notes that Joint Commission International keeps a list of accredited facilities outside the United States and that the American College of Surgeons recommends internationally accredited facilities. The CDC also cautions that accreditation does not guarantee a good outcome, so treat it as one factor, not a guarantee.

Before You Go: Lowering Your Personal Risk

Vaccinations and a travel health visit

The CDC recommends a travel medicine consultation 4 to 6 weeks before travel and being up to date on routine vaccines, with particular mention of hepatitis B for medical travelers. Ask your doctor whether you are protected.

Manage health conditions that slow healing

Poorly controlled diabetes, smoking and some medicines can raise the risk of wound infection. Discuss these with your doctor at home and with the overseas surgeon. A good surgeon may delay an operation until conditions are better controlled, and that is a sign of care, not an obstacle.

Ask about antibiotics in advance

Ask whether you will receive antibiotics around the time of surgery and whether any are prescribed afterwards, with generic names. Do not bring or take antibiotics on your own initiative unless a doctor has prescribed them for you.

Procedures That Deserve Extra Scrutiny

The CDC outbreak examples point to a few situations where extra questions are worthwhile.

Anesthesia injections into the spine

The fungal meningitis outbreak in Mexico followed epidural anesthesia. If your procedure involves an epidural or spinal anesthetic, ask who will perform it, whether medicines are drawn from single-use vials, and where those medicines are sourced. These are reasonable questions, and a competent anesthesiologist will answer them calmly.

Cosmetic procedures in small facilities

The mycobacterial outbreak in the Dominican Republic involved cosmetic surgery. Cosmetic procedures are often done in smaller outpatient settings where oversight varies. Confirm that the facility is licensed for the type of surgery you are having, and be especially careful about very low prices that may reflect shortcuts.

Injections and “treatments” outside medical settings

Be wary of fillers, fat injections or other injectable treatments offered in hotel rooms, salons or private homes. Sterile technique is hard to guarantee outside a proper clinical setting, and products used may not be what they are claimed to be.

Combining several procedures

Combining operations means longer time under anesthesia and more open tissue. Discuss with your surgeon whether staging procedures would lower your risk, rather than combining them only to save on travel.

During Your Stay

• Follow wound-care instructions exactly, and ask to be shown how to change dressings if you will do it yourself.
• Wash hands before touching dressings or drains.
• Avoid swimming pools, hot tubs, the sea and lakes until your surgeon says the wound is healed. The CDC lists swimming among activities to avoid during recovery.
• Choose lodging that is clean and allows you to rest; a recovery house with nursing support can help with drain and wound care.
• Attend every follow-up visit before you fly, so the surgeon can check the wound.

Warning Signs of Infection

If symptoms appear while you are still in the destination, contact your surgeon at once. If they appear after you are home, see a doctor promptly and tell them where and when you were treated, what was done and what medicines you received. Bring your operative report and discharge summary.

Some Infections Appear Late

Certain infections, including some mycobacterial infections mentioned in CDC outbreak reports, can develop slowly and appear weeks or months after surgery. Persistent lumps, draining sores or a wound that will not heal deserve medical attention even if you feel otherwise well. Tell any doctor you see about your treatment abroad, even if it seems long ago.

Putting It in Perspective

Most patients who travel to Latin America for treatment do not develop serious infections. Large private hospitals across the region apply modern infection-control practices, and many hold national or international accreditation. The documented outbreaks are a reminder that standards vary, and that the safest choices are licensed facilities, transparent answers to infection-control questions, and a clear plan for follow-up at home.

Frequently Asked Questions

Is infection risk higher if I have surgery in Latin America?

Risk depends on the facility and the procedure more than the country. The CDC says infections are the most common complication of medical tourism and has documented outbreaks linked to some facilities, so facility choice and infection-control questions matter.

What is CRE and why does my doctor want to test me?

CRE is a group of bacteria resistant to some of the strongest antibiotics. The CDC advises U.S. clinicians to consider screening patients who had an overnight stay in a health facility abroad within the past six months.

Should I take antibiotics with me just in case?

Only take antibiotics that a doctor has prescribed for you. Using them without guidance can cause side effects and contribute to resistance. Ask the surgeon what will be given and why.

When can I swim after surgery abroad?

Not until your surgeon confirms the wound is fully healed. The CDC lists swimming among activities to avoid during recovery because it can delay healing.

What should I tell my doctor at home?

Tell them where and when you were treated, what procedure you had, whether you stayed overnight in a hospital, and which medicines you received. Bring the operative report and discharge summary.
