A new CDC report identifies 69 outbreaks of waterborne diseases over a two-year period. There are 1,300 known patients, 73 hospitalizations and one death. Most cases include pools and hot tubs and a very specific parasite, known as cryptosporidium.

Cooling in the pool or spending a day in a water park are classic summer activities, but government health officials are warning that there are parasites lurking in common waters that even chlorine can not kill.

In a well-chlorinated pool, Giardia's parasite can survive for up to 45 minutes, and hepatitis A virus can survive about 16 minutes, according to the Centers for Disease Control and Prevention. A parasite called cryptosporidium or crypto can survive more than a week even in a well-groomed pool or water park, according to epidemiologist Michele Hlavsa.

Exposure to crypt in pools and water sites caused 4232 ailments from 2009 to 2017, according to a report published on Thursday by the CDC.

"Unlike perhaps a norovirus or E. coli that causes diarrhea or vomiting for several days, you may have diarrhea caused by cryptus within three weeks," said Hawswas, one of the authors of the study. is fun. "The report notes that these findings probably underestimate the real number of cryptoscopes. Study: Half of the Americans used pools as an alternative to a soul

"To protect ourselves from crypt, the best we can do is not to swallow the water we swim," said Halvas. to keep crypto at the pool, and the way we do it is not to swim or let the child swim when we have diarrhea. "

The CDC advises anyone who has had diarrhea to wait at least two weeks before to go into the pool, but a recent study found that 24% of respondents would go to the pool within one hour of diarrhea. Forty percent of Americans have admitted they were urinating in the pool as an adult. Although you can not catch crypto from the urine, it reacts with chlorine and reduces the amount of chemicals available to kill other pathogens.

The Water and Health Quality Council is a group sponsored by the Chromium Chemistry Unit of the American Chemical Industry Council, the Industrial Trade Association. From these eight, at least one check will cause the pool to stop immediately.

"We call this mini inspection where you use test strips to check the level of chlorine and pH before you get in," she said. "We, as swimmers or parents of young swimmers, have to take a more active role to make sure we have a fun and healthy time in the water this summer."
