Cryptosporidiosis

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease

no.svg

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype

no.svg

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder

no.svg

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

no.svg

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

Cryptosporidiosis is an illness caused by the parasite, Cryptosporidium. The condition is most commonly associated with watery diarrhea. Other signs and symptoms may include dehydration, weight loss, stomach cramps, fever, nausea and/or vomiting. Cryptosporidiosis occurs when the parasite enters the body, often through contaminated food and water or because of poor handwashing hygiene. Although cryptosporidiosis can affect all people, young children, pregnant women and people with severely weakened immune systems (i.e. those with AIDS; cancer and transplant patients who are taking certain immunosuppressive drugs; and those with inherited diseases that affect the immune system) are likely to develop a more serious illness. Medications such as nitazoxanide have been used to treat diarrhea in both adults and children. However, most people who have healthy immune systems will recover without treatment.[1][2][3]
