What is cryptosporidiosis?
Cryptosporidiosis (pronounced: “crypto-spore-idi-osis”) is a disease caused by a microscopic, single-celled parasite called Cryptosporidium parvum.

Who can get cryptosporidiosis?

Anyone, but it may be more common in persons under two years of age, those who travel, work with animals, or those that are in close personal contact with infected individuals.  People with impaired immune systems, such as people with HIV infection or that are receiving chemotherapy are more susceptible to the disease.  Cryptosporidium parvum has also been responsible for disease outbreaks in children in daycare centers.

What are the symptoms of cryptosporidiosis?

The major symptoms are watery diarrhea and abdominal cramping. Vomiting and low-grade fever may occur. Symptoms may come and go and generally last for two weeks, but may continue for a month. However, it is possible for people to be infected with Cryptosporidium parvum
