Summary
Travelers
Area of Science:
- Travel medicine
- Infectious diseases
- Public health
Background:
- Traveler's diarrhea (TD) affects 20-50% of travelers to developing countries.
- Infection is acquired through ingestion of fecally contaminated food or beverages.
- Enteric bacteria, primarily Escherichia coli, are the leading cause of TD.
Purpose of the Study:
- To evaluate the efficacy and safety of antimicrobial prophylaxis versus prompt treatment for traveler's diarrhea.
- To inform travelers and physicians about the risks of prophylactic antimicrobial drugs.
Main Methods:
- Review of existing literature on traveler's diarrhea causes, prevention, and treatment.
- Analysis of risks associated with widespread antimicrobial prophylaxis.
- Comparison of outcomes for prophylactic versus therapeutic antimicrobial use.
Main Results:
- Antimicrobial agents are not recommended for TD prevention due to side effects and lack of mortality.
- Prompt treatment with antimotility drugs (diphenoxylate, loperamide) or bismuth subsalicylate is effective for mild TD.
- Antimicrobial drugs (trimethoprim-sulfamethoxazole, trimethoprim, doxycycline) are effective for severe TD treatment.
Conclusions:
- Widespread antimicrobial prophylaxis for TD is not recommended.
- Prompt, effective treatment, including oral rehydration, is the preferred approach for managing TD.
- Travelers should be informed about the risks of prophylaxis and the benefits of prompt treatment.
