For example, the researchers said Arizona health officials used the system previous year to confirm a specific type of Cryptosporidium that spread to multiple swimming pools around Phoenix. Crypto can make otherwise healthy people sick for up to three weeks with watery diarrhea, stomach cramps, nausea and or vomiting.

Scientists say it's not clear if the number of outbreaks has increased or if detection methods have improved. 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. Unlike other bugs that sometimes spread in pools, crypto is not quickly killed by chlorine. The only way to ensure the health of the water once its been infected is to close the pool and treat it with extremely high levels of chlorine that are unsafe for humans to swim in.

Here's how the crypto parasite spreads: "If someone has a diarrhea incident in the water, and someone else comes around and swallows that contaminated water, it spreads", said Michele Hlavsa, chief of the CDC's Healthy Swimming Program.

While standard levels of chlorine kill most germs within a few minutes, Crypto can be extremely hard to kill.

Little kids learning to swim.

Take kids on bathroom breaks often, and check diapers in a diaper-changing area and not right next to the pool.

With the onset of warmer weather, the US Centers for Disease Control and Prevention (CDC) said today that reports of Cryptosporidium outbreaks linked to pools and waterparks are increasing. OH reported 1,940 infections in 2016, compared with no more than 571 in any one year from 2012 to 2015.

The CDC also recommends that parents make sure young people shower before they get into the water.

CryptoNet, launched in 2010, is the first U.S. DNA fingerprinting-based tracking system for illness caused by a parasite.

The team also detailed how a relatively new molecular testing network, CryptoNet, is helping states detect and track outbreaks, as well as identify the types that are sickening people. Examining the results combined with information on what patients were doing before they became sick will help CDC and its public health partners develop more effective strategies to stop the spread of Crypto.
