Summary

Cryptosporidium is a water-borne parasite that causes diarrhea and vomiting in humans. The disease is often spread through the feco-oral route, usually by drinking contaminated water or eating food that has been in contact with infected water.

Cryptosporidium is a common cause of diarrhea amongst travelers and can be particularly dangerous for those with weakened immune systems. Symptoms usually resolve within a week or two but can occasionally be fatal.
