Area of Science:

  • Infectious Diseases
  • Microbiology
  • Travel Medicine

Background:

  • Traveler's diarrhea is the most frequent health issue for individuals visiting developing nations.
  • Bacterial infections account for 50-80% of traveler's diarrhea cases.
  • Dietary measures are the primary method for preventing traveler's diarrhea.

Purpose of the Study:

  • To review the current understanding of traveler's diarrhea.
  • To discuss appropriate antibiotic choices for empiric therapy.
  • To highlight the role of newer antibiotics in managing resistant bacterial infections.

Main Methods:

  • Literature review of studies on traveler's diarrhea.
  • Analysis of antibiotic resistance patterns.
  • Evaluation of treatment guidelines for bacterial gastroenteritis.

Main Results:

  • Increasing resistance to trimethoprim-sulfamethoxazole and doxycycline is observed.
  • Fluoroquinolones are emerging as effective first-line empiric therapy.
  • Antimotility agents can alleviate symptoms but are contraindicated in specific cases (fever, bloody diarrhea).

Conclusions:

  • Antibiotic therapy is crucial for bacterial traveler's diarrhea.
  • Fluoroquinolones should be prioritized for empiric treatment due to resistance patterns.
  • Antibiotic prophylaxis is advised for high-risk travelers.
