Outbreaks of a parasitic infection linked to swimming pools and water playgrounds are increasingly being reported to CDC, with twice as many outbreaks in 2016 as in 2014.
At least 32 outbreaks caused by Cryptosporidium, or Crypto linked to swimming pools or water playgrounds in the United States were reported in 2016, compared with 16 outbreaks in 2014, according to preliminary data published today in CDC’s Morbidity and Mortality Weekly Report. The parasite can spread when people swallow something that has come into contact with the feces (poop) of a sick person, such as pool water contaminated with diarrhea.
In comparison, 20 Crypto outbreaks linked to swimming were reported in 2011, 16 in 2012, and 13 in 2013. It is not clear whether the number of outbreaks has increased or whether better surveillance and laboratory methods are leading to better outbreak detection.
