Overview
Cryptosporidium parvum is a type of single-celled parasite that is found in warm-blooded animals and humans. It can cause cryptosporidiosis, a gastrointestinal illness, which is characterized by diarrhea, abdominal pain, nausea, and sometimes vomiting. It is transmitted through contact with contaminated water, food, or objects. Cryptosporidium parvum is especially significant as it is one of the most common causes of waterborne disease in the United States, and can be difficult to treat, making it important to be aware of the ways to prevent its spread. The best way to protect oneself and others from the illness is through proper hygiene and avoiding contact with contaminated water, food, or objects. Additionally, municipal water systems are taking steps to reduce the spread of Cryptosporidium parvum through filtration, chlorination, and ultraviolet disinfection.
