In a follow-up to the Cryptosporidium outbreak in Maricopa County, Arizona, county health officials say the case tally is now at 32, according to a local media report.


Some four public swimming pools have been linked to the parasitic outbreak. Super-chlorination protocols are being used to help eliminate the resistant protozoa.

Cryptosporidiosis, or Crypto, is a microscopic parasite causing a diarrheal illness. Common symptoms include: diarrhea, stomach cramps or pain, dehydration (which is often most serious in the very young and the very old), nausea, vomiting, fever and weight loss. Symptoms usually begin 2 to 10 days after infection and normally last for one to two weeks. Once a person is infected, the parasites live in the intestines and are passed in the stool.
