Travel Safe: Your Guide to Staying Healthy Abroad
"Expert tips and insights from Argentina's First Travel Medicine Center to ensure a healthy and worry-free trip."
Globally, travel is booming, with 1.5 billion people traveling by air and 700 million crossing international borders annually. These numbers highlight the need to understand and manage the health risks associated with travel.
Your health risk during travel depends on several factors: where you're going, your health, travel purpose, trip length, time of year, accommodation, activities, and lifestyle. Backpacking, visiting family in rural areas, longer trips, and living abroad increase health risks.
Recognizing these risks, Argentina established its first Travel Medicine Center (CEMEVI) in a public hospital in 2008. This initiative addresses a critical need, providing travelers with essential pre- and post-travel medical advice. Understanding CEMEVI's experiences can help you stay healthy on your next adventure.
Standards for Travel Medicine
The Faculty of Travel Medicine of the Royal College of Physicians and Surgeons of Glasgow issued recommendations in 2012 to raise standards and make travel medicine services more uniform, with the goal of better protecting travellers. The Faculty describes its role as supporting professionals through education, training, continuing professional development, examinations, and assessment, while promoting high standards of care and traveller safety. A 2026 abstract outlines a strategy for globally applicable standards intended to support consistent minimum service standards regardless of profession or geography. The supplied sources describe these aims but do not specify the limitations of current accepted methods.
A Developing Field
A history of travel medicine is represented in *Travel Medicine: Tales Behind the Science*, a collection of 40 essays by recognized contributors to the field, organized into nine sections covering topics such as history, vaccines, research, pilgrimages, and space travel. One milestone highlighted by the International Society of Travel Medicine is Dr. Vincenzo Marcolongo’s establishment of IAMAT in 1960. The organization was dedicated to helping healthcare providers and travellers access care around the world, including in situations where language could complicate finding a doctor. A separate account describes medical travel in the 18th and 19th centuries as the emergence of modern medical tourism.
What are the Most Common Travel Health Risks?
When you travel, being aware of potential health issues is crucial. A significant number of travelers encounter health problems, highlighting the need for preparation and awareness. For every 100,000 travelers to developing countries staying at least a month, these are the approximate risks:
- 50,000 may face a health issue.
- 8,000 might require medical assistance.
- 5,000 could need bed rest.
- 1,100 may be unable to work.
- 300 might need hospitalization.
- 50 could need evacuation from their destination.
- Sadly, 1 may die from a travel-related illness.
Research Across Travel Health
A 2026 review on “travel microbiota” examines how travel may affect the human microbiota and highlights differences across transportation modes; its stated aim is to build a framework for understanding travel health and microbiota’s role in managing travel-related risks. A report on a private healthcare center’s first 20 months of travel consultations in Bogotá, Colombia, notes that most patients reported no significant medical history (9 of 24, or 37.5%), while cardiovascular disease was the most common identified medical condition (4 of 24, or 16.7%). The supplied journal pages also identify *Travel Medicine and Infectious Disease* and the *Journal of Travel Medicine* as venues for current peer-reviewed research, including work on disease prevention and treatment, clinic management, and immunizations.
Comparing Travel-Health Services
A 2011 study compared recommendations from pharmacist travel-health specialists and primary care providers for travel-related medications and vaccinations, as well as patient compliance, in a college health setting. The supplied source summary does not report the study’s results, so it does not establish which provider group made more appropriate recommendations or achieved better compliance. Separate 2026 comparisons describe evaluating online travel-medicine services by cost, visit format, fulfillment, prescriptions, vaccine access, and clinical quality. Another comparison covers Passport Health, hospital and county clinics, CVS MinuteClinic, Costco pharmacy, and online travel health, but the supplied summaries do not provide comparative findings.
How to Prepare for a Healthy Trip?
Planning is key. The Travel Medicine Center (CEMEVI) in Argentina, found that most travelers they assisted came in before their trips. By visiting a travel clinic 4-6 weeks before traveling, you can get personalized advice, necessary vaccinations, and essential health information.
Evidence, Advice, and Clinical Judgment
A review of artificial intelligence tools in pre-travel health consultations asks which tools have been evaluated, what conclusions the evidence supports, and what patient-safety and implementation gaps remain. It also considers how travel clinics might use AI without replacing specialist clinical judgment. Separately, a prospective GeoSentinel Network project aimed to describe the epidemiological and clinical patterns of travel-related healthcare encounters among travellers seen by its global network of travel and tropical medicine providers. An analysis of web-based travel health advice found significant gaps in topic coverage and called for accessible pre-travel advice from patient organisations; it also identified the need for research on how such information influences travellers with chronic disease.
Mobility and Public Health
Travel and globalization have transformed public health and disease control, bringing economic, cultural, and technological changes while creating new risks for infectious disease spread. A 2024 source likewise describes international travel in an increasingly interconnected world as contributing to infectious disease spread and characterizes travel medicine as playing a vital role. At the service-delivery level, a report on a public hospital in Buenos Aires Province, Argentina, concluded that implementing a Travel Medicine Center in the public health system was feasible and fruitful. These sources connect cross-border movement with disease-control challenges and the role of accessible travel-medicine services.
CEMEVI's data showed South America as a top destination for travelers, with 66% heading there, followed by Asia (13%) and Africa (13%). Most travelers stayed less than four weeks, and the majority traveled for leisure (80%). Key steps for planning a healthy trip include:
By taking these steps, you can significantly reduce your risk of health issues while traveling, ensuring a safer and more enjoyable experience.
