Posttravel screening identifies hidden infections and health risks for travelers, improving health outcomes. Tailored screening, integrated with prevention, is crucial for effective travel medicine.

Area of Science:

  • Travel Medicine
  • Public Health
  • Preventive Medicine

Background:

  • Posttravel screening is vital for detecting occult infections and health risks in travelers.
  • Screening strategies must be individualized based on travel type and associated risks.
  • Integrating screening with primary prevention enhances cost-effectiveness and reduces future travel-related illnesses.

Purpose of the Study:

  • To review available screening tests for sexually transmitted diseases (STDs), tuberculosis, and parasitic infections.
  • To propose recommended posttravel screening approaches, considering cost-effectiveness where data is available.
  • To advocate for broadening screening to include major causes of mortality like atherosclerotic and neoplastic diseases and trauma.

Main Methods:

  • Medical history to define individual risks and guide tailored laboratory testing.

  • Review of current screening tests for infectious diseases (STDs, tuberculosis, parasitic infections).
  • Consideration of major mortality causes in North Americans (atherosclerotic, neoplastic diseases, trauma) for inclusion in screening.

    • Main Results:

    • Available screening tests for STDs, tuberculosis, and parasitic infections were reviewed.
    • Recommended screening approaches were proposed, though cost-effectiveness data is limited for many tests.
    • The study highlights the benefit of including screening for major mortality causes beyond infectious diseases.

    Conclusions:

    • Posttravel screening is a key secondary prevention strategy in travel medicine.
    • Tailored screening, informed by medical history and travel type, is essential.
    • Expanding screening to include non-communicable diseases and trauma can significantly benefit traveler health.
