    Short trips to developing countries pose health risks for travelers. About 15% experienced health issues, with infections like giardiasis and amebiasis being common, highlighting the need for travel health awareness.

    Area of Science:

    • * Travel Medicine
    • * Infectious Diseases
    • * Public Health

    Background:

    • * Short-term travel to developing nations is common.
    • * Understanding associated health risks is crucial for traveler well-being.
    • * Previous studies may not fully capture risks for shorter durations.

    Purpose of the Study:

    • * To assess the health risks for travelers undertaking short visits (under three months) to developing countries.
    • * To quantify the incidence of specific infections and overall health problems.
    • * To compare health outcomes with a control group traveling to developed regions.

    Main Methods:

    • * A follow-up study involving 10,524 travelers to developing countries.
    • * A control cohort of travelers to the Greek or Canary Islands.

  • * Questionnaires collected data on pretravel preparations and health issues, with physician confirmation of infections.

    • Main Results:

    • * 15% of travelers to developing countries reported health problems; 8% sought medical consultation.
    • * Common infections included giardiasis (7/1,000 traveler-months), amebiasis (4/1,000), and hepatitis (4/1,000).
    • * No cases of typhoid fever or cholera were reported; malaria and other serious infections were rare.

    Conclusions:

    • * Short-term travel to developing countries is associated with a significant risk of illness.
    • * Giardiasis, amebiasis, and hepatitis are prevalent infections among these travelers.
    • * Preventive measures and awareness are essential for mitigating health risks during international travel.
