But diving into the development to beat the incalescence could expose one to parasites which may cause severe illness, the Centers for Disease Control warns.

A fresh report issued Friday showed that a parasitic infection is often known as Cryptosporidium, or crypto, is growing. Between 2009 and 2017, the CDC said 444 crypto outbreaks – representing some 7,465 infections – were reported in 40 states. Those figures represent an improvement of about 13 percent per year.

The highest single source for the outbreaks was contaminated chlorinated water, such as pools and water playgrounds, the CDC said. Unlike other germs that typically are killed by common pool disinfectants, that include chlorine, crypto is quite capable of surviving in properly treated water for as much as every week.

Crypto can have serious health consequences, mostly caused due to profuse, watery diarrhea that will remain effective for twenty days. Other symptoms include dehydration, nausea, vomiting, fever and losing weight.

  • How you can protect yourself from crypto: Don’t swim or let children swim if sick with diarrhea.
  • Don’t swallow pool water. Don’t urinate inside of the water.
  • Take kids on bathroom breaks and look diapers every hour.
  • Change diapers in a very very bathroom or diaper-changing area—not poolside—to keep germs away from the pool.
