CDC Reports That Pools In The U.S. May Be Exposed To Crypto-Parasites


It was discovered that inadvertent ingestions in chlorinated pool water may cause cryptosporidium, also known as ‘crypto’, moreover, the microscope parasite can cause stomach pain, nausea and diarrhea  that remains for over three weeks.

The number of recorded crypto cases has increased at pools and water parks in the U.S. over the last two years, according to the Centers for Disease Control and Prevention. It has been recorded the around 16 crypto conditions were found in 2014, according to the CDC’s Morbidity and Mortality Weekly Report on Thursday. However, there were 32 cases recorded in 2016.

Cases Recorded

CDC has recorded around 1,940 cases infected in Ohio, the state with most infections, in 2016 compared to previous year’s 600 cases.

CDC has found the reason behind the massive outbreak in numbers of infections.

“It is not clear whether the number of outbreaks has increased or whether better surveillance and laboratory methods are leading to better outbreak detection,” it said in a press statement.

Crypto parasites have potentials to spread easily across pools and water playgrounds, but they cannot be easily removed. Chlorinated water is the best environment for crypto parasites as they can live up to ten days in chlorinated aqua.


The way to put an end to the spread of the parasites is to shut the pools down once they are proven infected. Furthermore, safety procedures for cleaning the pool using high levels chlorine, to which is unsafe for humans in case they get subjected, should be adopted.

So, swimmers and parents should take care of themselves while swimming in pools as they should not swallow any of the pool water and they should have a shower once they get out of the pool.

CDC also warns parents and swimmer of swimming when sick and that they should wait at least two weeks before any symptoms of potential cases of crypto to ease off or disappear.
