Cryptosporidium Infection

Cryptosporidium parvum (Crypto) is a parasite in fecal matter contaminated food or water. It is highly resistant to normal levels of chlorine and can survive in pools and drinking water. People usually get cryptosporidium from swallowing contaminated water, eating contaminated food, or coming into contact with contaminated feces. Ingestion of as few as two to ten cryptosporidium oocysts, or parasites, can cause infection. The CDC has said that infections from Crypto have doubled since 2014.

The CDC has documented over ten cryptosporidium outbreaks from contaminated water in the United States since 1988. It has infected thousands.

Cryptosporidium Infection Symptoms

After swallowing the parasite, symptoms of cryptosporidium infection, or cryptosporidiosis generally appear after a week. Signs that one is infected by a cryptosporidium parasite include the following:

  • Diarrhea
  • Abdominal cramping
  • Fatigue
  • Fever
  • Nausea
  • Loss of appetite

Those at increased risk of infection with cryptosporidium include people with weak immune systems, the elderly, small children, and pregnant women.


Complications of cryptosporidium infection include:

  • Malnutrition resulting from poor absorption of nutrients from your intestinal tract (malabsorption)
  • Severe dehydration
  • Significant weight loss (wasting)
  • Inflammation of a bile duct, which is the passage of the liver, gallbladder and small intestine
  • Inflammation of your gallbladder, liver or pancreas

Cryptosporidium infection itself isn’t life-threatening. However, if you’ve had a transplant or if you have a weakened immune system, developing complications can be dangerous.
