			* Worldwide, but more in tropical and subtropical areas
			* Mostly associated with HIV infection, but can also cause a traveller's diarrhea

			=== Life Cycle ===
			* '''Oocysts''' are shed into the environment
			** Each contains one '''sporoblast'''
			** Remain viable for months
			* Oocysts sporulate in the environment before becoming infectious
			** Sporoblasts dividing and maturing into two '''sporocysts''', which in turn divide and mature into two '''sporozoites''' each
			* The sporulated oocyst (containing four sporozoites) is ingested
			* In the proximal small bowel, the sporozoites are released and develop into '''merozoites'''
			* The merozoites go through asexual reproduction, eventually followed by sexual reproduction that results in development of an immature oocyst, which is shed
