A recent CDC report found 69 waterborne outbreaks over a two-year period. There were 1,300 known patients, 73 hospital admissions and one death. Most cases involved pools and whirlpools, as well as a very specific parasite known as Cryptosporidium.
Cooling in the pool or a day at a water park are classic summer activities, but government health officials warn that parasites lurk in municipal waters that can not kill even chlorine.
In a well-chlorinated pool, the Giardia parasite can survive for up to 45 minutes, and the hepatitis A virus can survive about 16 minutes, according to the Centers for Disease Control and Prevention. According to epidemiologist Michele Hlavsa, a parasite called Cryptosporidium or Crypto can survive more than a week even in a properly treated pool or water park.
Exposure to cryptos in pools and water playgrounds caused 4,232 diseases between 2009 and 2017. According to a report released on Thursday by the CDC. People, especially children who swim too early after diarrhea, can spread the parasite.
"Unlike perhaps Norovirus or E. coli, which cause diarrhea or vomiting for a few days, you may have diarrhea caused by crypto for up to three weeks," said Hlavsa, one of the authors of the study. "That's not fun."
According to the CDC, the number of crypto-related diseases associated with "purified recreational water" is highest from June to August and increased by 14.3% annually from 2009 to 2016. The report found that these results are likely to underestimate the actual number of crypto outbreaks.
Poll: Half of Americans used swimming pools as an alternative to showering
"Infectious Soup" in the Water Park: Mother "To Us Protecting cryptos, the best thing we can do is not to swallow the water we swim in, "Hlavsa said. "We want to keep Krypto out of the pool in the first place, and the way we do it is not to swim or let our child swim when we have diarrhea."
The CDC advises anyone with diarrhea Wait at least two weeks before getting into a pelvis, but a recent survey found that 24% of respondents would go into a pelvis within an hour of diarrhea.
This survey, submitted by the Water Quality and Health Council, found that 40% of Americans said they had urinated in a pool as an adult. While crypto can not be captured from urine, it does react with chlorine and reduces the amount of chemicals available to kill other pathogens.
The Water Quality and Health Council is a group funded by the Chlorine Chemistry Division of the American Chemistry Council, an industry association.
Around eight in ten pool inspections, according to the CDC, are a serious violation of health regulations. Of these eight, at least one inspection will cause the pool to close immediately.
Hlavsa recommended to go online and check the inspection results on the website of the local or state health ministry before entering a pool or swimmers doing their own inspection when they arrive.
"We call this a mini-inspection, in which you use test strips before boarding to check the chlorine content and pH," she said. "We as swimmers or parents of young swimmers need to take a more active role to make sure we have a fun, healthy and safe time in the water this summer."
