Cryptosporidiosis is a disease that causes diarrhoea lasting about one to two weeks, sometimes extending up to 2.5 months among the immunocompetent and becoming a more severe life-threatening illness among immunocompromised individuals. Cryptosporidium is a common cause of gastroenteritis. Cryptosporidiosis is common in HIV-infected individuals.
