Meanwhile, the only way to ensure your own health is to take precautions when swimming in pools or playing at water parks. Comparatively, 13 crypto outbreaks in the year 2013, 16 in 2012, and 20 in 2011 connected to swimming were reported.

The CDC is unsure whether the sharp increase in reported cases is the result of better testing and detection methods; however, the agency wants everyone to be more careful in order to avoid the risk of parasite infection.

Big outbreaks in 2016 included one in Arizona that sickened an entire Little League team and a cluster of outbreaks in OH that started in a water park and spread to nearby pools, contributing to almost 2,000 cases statewide, adding to details published in CDC's Morbidity and Mortality Weekly Report.

Hlavsa explained that crypto is resistant to chlorine, and can survive up to 10 days in even properly chlorinated pool water.

"Health care providers should also instruct cryptosporidiosis patients not to go back into the water until they have been diarrhea-free for two weeks", the team added.

The eighth installment in "The Fast and the Furious " franchise has pulled in 207.1 million USA dollars to date in North America. But whether " Guardians " can turn the tide for summer sequels will be a much-followed story line as the season progresses.

Next time you decide to take a dip in a pool, make sure you don't swallow the water. The parasite is notoriously hard to kill and can survive up to 10 days in chlorinated water. That means an average of 8,000 people a year suffer through up to three weeks of watery diarrhea, stomach cramps, nausea and sometimes vomiting - most often because they swallowed contaminated pool water. They recommend closing pools and treating the water with high levels of chlorine, known as hyperchlorination when diarrheal incidents or crypto outbreaks occur in a swimming pool or water playground.

The states will be largest number people who were sickened past year were OH (1,940) and Arizona (352), according to the news release. For example, in the year 2016 Arizona used CryptoNet to confirm spread of a particular type of Crypto in multiple swimming pools in the Phoenix area. Pool. Eww. And where there's No. 2 there could be Cryptosporidium, aka Crypto, a parasite that lives in the intestine of infected humans (or animals) and is the most common cause of diarrhea.

CDC is working to improve CryptoNet with more advanced DNA fingerprinting techniques. CDC encourages swimmers to help protect themselves, family, and friends from Cryptosporidium and other germs in the water we swim in.
