| Traveler's diarrhea is an infectious disease caused by either bacteria (most common), viruses, or protoza. The most common cause of traveler's diarrhea is enterotoxigenic ''E. coli'' (ETEC), which is responsible for up to 80% of all cases. Other common bacterial causes include other ''E. coli'' strains, ''Campylobacter'', ''Shigella'', and ''Salmonella''. Common viral causes include norovirus, rotavirus, or astrovirus infection. Common protozoal causes include ''Giardia'', ''Entamoeba histolytica'', and ''Cryptoosporidium''. | | Traveler's diarrhea is an infectious disease caused by either bacteria (most common), viruses, or protoza.

Overview
Traveler's diarrhea is an infectious disease caused by either bacteria (most common), viruses, or protoza. The most common cause of traveler's diarrhea is enterotoxigenic E. coli (ETEC), which is responsible for up to 80% of all cases. Other common bacterial causes include other E. coli strains, Campylobacter, Shigella, and Salmonella. Common viral causes include norovirus, rotavirus, or astrovirus infection. Common protozoal causes include Giardia, Entamoeba histolytica, Cryptoosporidium, and Cyclospora.
Causes
- The most common causative agent associated with traveler's diarrhea is enterotoxigenic Escherichia coli (ETEC).
- In infants and children, it is estimated that nearly 70% of diarrhea is due to viruses.
Common causes of traveler's diarrhea are shown below:
