[1][2] Treatment of gastrointestinal infection in humans involves fluid rehydration, electrolyte replacement, and management of any pain.

Cryptosporidium causes cryptosporidiosis, an infection that may present as a diarrhea, sometimes with a persistent cough in immunocompetent hosts.

It results in cyst stages that are excreted in feces or through inhalation of coughed on fomites and are capable of transmission to a new host.

[7] Cryptosporidiosis is typically an acute, short-term infection, but can recur through reinfection in immunocompetent hosts, or become severe or life-threatening in immunocompromised individuals.

[12] The Cryptosporidium spore phase (oocyst) can survive for lengthy periods outside a host.

Ultraviolet light treatment at relatively low doses will inactivate Cryptosporidium.

The oocytes may be seen by microscopic examination of a stool sample, but they may be confused with other objects or artifacts similar in appearance.

Testing of water, as well as epidemiological study, are necessary to determine the sources of specific infections.
