Cryptosporidiosis Causes

It is caused by a parasite called Cryptosporidium parvum. These parasites live in the intestines of infected people and animals. They can also contaminate objects and surfaces that people touch. They may also be in soil where food is grown. The parasite can also be in recreational waters where people swim.

The infection is caused by swallowing the parasite. When the parasite enters your intestine, it comes out of its shell. It will multiply and may cause an infection. Eventually, it is passed from your body through a bowel movement.

Some sources of cryptosporidiosis are:

• Humans and animals:
  • Contact with diapers or clothing that are contaminated with the infection
  • Contact with animal feces by touching animals, cleaning cages, or visiting barns
  • Sexual activity that involves contact with feces
• Food:
  • Eating food grown in, or contaminated by, infected soil
  • Drinking unpasteurized milk, dairy products, or apple juice
  • Eating food that was handled by someone who is infected or washed in contaminated water
• Water:
  • Accidentally swallowing water in contaminated recreational water, such as a lake, ocean, bay, stream, hot tub, swimming pool, or water park
  • Drinking water or ice that is contaminated
