ABSTRACT
Cryptosporidium is one of the most common human enteropathogens worldwide, but it is most common in less developed countries. It can be diagnosed by detection of oocysts, oocyst antigens, or sporozoite DNA in stool specimens. A probable case of cryptosporidiosis was defined as member of the club with illness and having one or more of the following symptoms: diarrhoea abdominal cramps, loss of appetite, vomiting, without laboratory confirmation of Cryptosporidium infection. Cryptosporidium is transmitted by the faecal–oral route either by direct contact with an infected human or animal or their faeces, or indirectly through contaminated food or water. It is apicomplexan oocyst-forming protozoan parasite that infects a broad range of hosts, causing gastrointestinal illness in humans and young animals. It has a monoxenous life cycle completed within the gastrointestinal tract of a single host. Infection follows ingestion of the oocyst life-cycle stage, which is shed in faeces. Swimming pool outbreaks are often associated with mismanagement and inadequate pool water filtration.
