3. “Antimicrobial resistance poses a
fundamental threat to human health,
development, and security. The
commitments made today must now
be translated into swift, effective,
lifesaving actions across the human,
animal, and environmental health
sectors. We are running out of
time."
Dr. Margaret Chan

Core Competencies
5. Objectives
• Recognize the limited number of acute diarrheal clinical
scenarios that require antimicrobial therapy.
• Use microbiologic susceptibility data to determine the
appropriate empiric therapy for traveler’s diarrhea and when
clinician-prescribed, self-treatment is indicated.
• Understand role of clinicians in reducing the use of
antimicrobials purchased without a prescription for acute
diarrhea in some settings.

• Among gram-negative
organisms:

• Salmonella
• Campylobacter
• Self-treatment exposes
patients to harm
