Cryptosporidiosis or crypto is a disease caused by Cryptosporidium, a protozoan parasite. It appears only in mammals and provokes acute short-term infections because of contaminated water, in most of the cases. In people with regular immune systems it usually provokes diarrhea, but in those immunocompromised, like those suffering of AIDS, the disease is usually severe and it can be fatal.
The disease was first identified just in 1976, although it is one of the most common waterborne illnesses that exist in the whole world. However, the organism – Cryptosporidium, was first described by Tyzzer in 1907. In order to learn more about the parasite and the disease, you need to see the next short documentary made by two high school students for a school project.
As you noticed, a lot of information which is very useful is condensed in just 4 minutes. The disease is very unpleasant (as any disease actually) and you need to take the best measures to avoid it if you plan to travel to places where there are water problems. Take care of your health, especially if you know you have a weak immune system which cannot fight easily such a parasite.
