EEIP RIDRM Cryptosporidiosis
Cryptosporidiosis is a diarrheal illness caused by the microscopic parasite Cryptosporidium. The parasite has a protective shell that helps it survive outside the body for long periods of time. The shell also prevents the penetration of disinfectants. In the United States, Cryptosporidium is a leading cause of waterborne disease in humans.
Actions Required and Control Measures
Reporting Requirements - Category 2
Cryptosporidiosis is physician reportable by mail within 12 hours of recognition or strong suspicion to both the Connecticut Department of Public Health (DPH) and the local health department (LHD). The director of any clinical laboratory must also report laboratory evidence of Cryptosporidium to both the DPH and the LHD.
