(don't forget subtitle)
Cryptosporidium is a microscopic parasite that causes the diarrheal disease Cryptosporidiosis. The parasite is surrounded by an outer shell that allows it to stay outside the body for long periods of time. It is very tolerant to chlorine disinfectant, so it is most commonly spread through local/ communal pools.
Diagnosis: Examinations of stool samples using a modified acid-fast based staining culture.
Very infrequent, but not enough to be considered and epidemic when it does arise.
Disease Course/ Symptoms
Can be debilitating to immunocompromised people living with HIV/ AIDS, but other than that, its just a pretty bad stomach bug.
It can be spread to anyone, by anyone with the disease.
