Last week the Centers for Disease Control (CDC) warned the public about a parasite that can live up to ten days in chlorinated pool water and possibly cause severe gastrointestinal issues like diarrhea. One of the main causes of outbreaks in treated water, including hot tubs and swimming pools, is a resistant parasite called Cryptosporidium. Cryptosporidium is spread through contaminated food or feces. Experts suggest you try not to swallow water in recreational waters, including lakes and water parks, and refrain from swimming for at least a week if you have recently had any gastrointestinal problems to avoid passing an infection to others. There is no treatment for infection except to just stay hydrated and let it run its course.
The CDC recommends that swimmers shower before getting in the pool to prevent them from carrying infectious bacteria into the water. Young children, pregnant women and people with compromised immune systems are most susceptible to infection.
