Diarrhea and the Petting Zoo
Now that it is Spring Time, trips to the Zoo and to Pools will become more frequent… consider them as potential environmental exposure sites.
Petting Zoos, Farmers Markets and Fairs, and Swimming Pools (especially kiddie swimming pools) are known sources of enteropathogens that can cause diarrhea (sometimes bloody).
Consider these on your DDx of vomiting/diarrhea.
Ask about these possible exposure sites along with Travel History and Nontraditional Pets.
