Infectious diarrhea constitutes a major source of morbidity and mortality for all age groups. The focus of this article is to identify high risk host and pathogenic risk determinants of enteric infections, discuss pathophysiologic mechanisms for diarrhea, review conventional and upcoming therapeutic managements of bacterial, protozoal or viral-type diarrhea, and describe the integral role of the pharmacist in the overall care of patients having this illness.
