It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system ) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune disorders ) individuals, resulting in watery diarrhea with or without an unexplained cough. Cryptosporidiosis was one of the defining illnesses for acquired immunodeficiency syndrome (AIDS) before the discovery of the human immunodeficiency virus (HIV). Travelers to developing countries might be at increased risk for infection because of poorer water treatment and food sanitation, although cryptosporidiosis happens all over the world.

[4] A review of the first 7 cases of cryptosporidiosis led to the conclusion that it was predominantly a disease of the immunocompromised, [5] although later it was also found to be widely prevalent among immunocompetent children. Millions of cryptosporidia can be released in a bowel movement from an infected human or animal, and the number of cryptosporidia needed to cause infection is very low. Food handlers, healthcare workers and childcare workers should be excluded from work until diarrhoea has ceased. Young animals are more susceptible than adults.

The recent occurrence of large water- and foodborne outbreaks in several EU countries, as well as the results of many surveys of human and animal cryptosporidiosis, indicate that this parasite is widespread. All rights reserved. Malnutrition and HIV status are also important contributors to the prevalence of Cryptosporidium and Giardia in African countries. It is primarily spread through the fecal-oral route , often through contaminated water; [2] [3] recent evidence suggests that it can also be transmitted via fomites in respiratory secretions.

Cryptosporidiosis Surveillance — United States, 2011–2012. Epidemiology and detection as options for control of viral and parasitic foodborne disease. There are studies of meta-analysis on Cryptosporidium infection focused on low- and middle-income countries [ 7] and person with HIV [ 8 ]. Several classes of drugs with good efficacy exist for Giardia, but dosing regimens are suboptimal and emerging resistance threatens clinical utility. Cryptosporidium infection, 8 patients (18.6%) were reported to have Cryptosporidium infection of the common bile duct (Lopez-Velez et al, 1995). First discovered by Ernest Edward Tyzzer in the year 1907 in the gastric mucosa of mice, [3] Cryptosporidium remained largely unrecognized as a human pathogen until the first reported case in 1976 in an immunocompetent child.
