Cryptosporidiosis is a diarrheal disease caused by the Cryptosporidium parasite. It primarily affects the intestines of humans and various animals. It is a common cause of recreational water illness worldwide, particularly problematic for individuals with weakened immune systems.
The *Cryptosporidium* parasite was first identified in mice in 1907, but it wasn't recognized as a human pathogen until the 1970s. It gained significant attention with the 1993 Milwaukee outbreak, the largest waterborne disease outbreak in US history. Its importance grew further as a common opportunistic infection in individuals with HIV/AIDS.
Cryptosporidiosis spreads through the fecal-oral route by ingesting oocysts, the infective form of the parasite. This commonly occurs through contaminated drinking or recreational water, as oocysts are highly resistant to chlorine. It can also spread through contaminated food or direct contact with infected people or animals.

Cryptosporidiosis is an important cause of gastroenteritis in Australia, typically spread through contaminated water, food, and contact with infected people or animals. It has historically shown a seasonal pattern, with peaks in summer and, in some livestock-dense states, spring. Multiple pool‑associated clusters have been reported in recent years, prompting public health alerts and swimming pool closures.
