Thousands of cases have been reported since 2009, with a 13 percent rise in reported cases every year! 

Just when you thought that you were having clean and safe fun at the pool this summer, the Center for Disease Control (CDC) releases a warning over a rise in "crypto" parasite cases (Cryptosporidiosis), which is found in pools. Crypto will churn your stomach and give you a case of "watery diarrhea."


The parasite can live in the water for several days, despite the chemicals and chlorine in the pool, so anyone is at risk – especially children, women who are pregnant, or those with weak immune systems. Once you're finished swimming, hit the showers immediately and wash yourself off with hot water and plenty of soap to prevent the risk of being infected.

Since 2009, there has been a 13 percent increase in cases every year, so be very cautious if you plan to go swimming in the pool anytime soon. 

According to the CDC's report, "For the period 2009–2017, public health officials from 40 states and Puerto Rico voluntarily reported 444 cryptosporidiosis outbreaks resulting in 7,465 cases. Exposure to treated recreational water (e.g., in pools and water playgrounds) was associated with 156 (35.1%) outbreaks resulting in 4,232 (56.7%) cases."

Of those 7,465 cases, it was reported that 200 people were hospitalized and one individual had died.

What to Do

If you become infected with the parasite, some symptoms may include watery diarrhea, nausea, vomiting, fever, stomach pain, dehydration, and weight loss. The symptoms typically appear two-10 days prior to infection.

The parasite requires no medical treatment, but if your symptoms begin to worsen, consult with your doctor immediately and keep sick children out of the pool, wash your hands with soap and hot water, and remove your shoes before entering the house.
