Swimming Pool Sickness

Swimming Pool Sickness | Weekly Bulletins | Andrew Weil, M.D.
1 min

The bug is Cryptosporidium (Crypto for short), an organism that can cause outbreaks of diarrhea lasting up to three weeks. You (or your kids) can get infected by swallowing water from contaminated pools, lakes and rivers, the CDC warns. The bugs can survive even in chlorinated water for up to 10 days or more. The CDC reports that in the U.S. from 2009 to 2017 there were nearly 450 outbreaks of crypto, which led to 7,465 illnesses. Day care centers are another common source of infections. Here the parasite can be spread by infected youngsters who contaminate surfaces. Raw milk, and raw apple cider have also been linked to outbreaks. In addition to not swallowing water while swimming, the CDC advises against swimming if you (or your kids) have diarrhea. It also recommends avoiding swimming for at least two weeks after the symptoms resolve. Other precautions: wash your hands frequently, and especially after using the toilet, changing diapers, caring for someone with diarrhea or handling animals.
