Cryptosporidium

Cryptosporidia is a parasite that can cause an acute gastrointestinal illness. The most common symptom is profuse, watery diarrhea accompanied by cramping abdominal pain and, less frequently, fever, nausea, and vomiting. Transmission is primarily fecal-oral, and often ingested through contaminated water. The average incubation period is 7 days (range 1-12).
