  • Make sure that persons with diarrhea, especially children, wash their hands carefully and frequently with soap to reduce the risk of spreading the infection.

  • Wash raw fruits and vegetables before eating.

  • Always wash hands after contact with farm animals, pets, animal feces, and animal environments.

Avoid swallowing recreational water

  • Do not swallow water while swimming in swimming pools, hot tubs, interactive fountains, lakes, rivers, springs, ponds, streams, or the ocean.
    • Note: Cryptosporidium is chlorine resistant and can live in swimming pools, even those that are properly treated, for days.
  • Protect others by not swimming if you are experiencing diarrhea. If diagnosed with cryptosporidiosis, do not swim for at least 2 weeks after diarrhea stops.
  • Healthy Swimming
    CDC; Contains information on recreational waterborne illnesses.

Avoid drinking untreated water

  • Do not drink untreated water from shallow wells, lakes, rivers, springs, ponds, or streams.
  • If you are unable to avoid drinking water that might be contaminated, then drink bottled water or treat the water yourself by::
    • Heating the water to a rolling boil for at least 1 minute.
    • Using a filter that has been tested and rated by National Safety Foundation (NSF) Standard 53 or NSF Standard 58 for cyst and oocyst reduction; filtered water will need additional treatment to kill or inactivate bacteria and viruses.
    • Do not rely on chemical disinfection of Cryptosporidium because it is highly resistant to inactivation by chlorine or iodine.
