CDC Issues Warning for<br />‘Crypto’ Fecal Parasite in Pools Health officials in the USA are warning<br />people of a parasite, cryptosporidium,<br />that can potentially cause chronic diarrhea. Infected healthy adults will experience "profuse,<br />watery diarrhea" for as long as three weeks, with the effects being worse for<br />children, pregnant women and those<br />with compromised immune systems. Cryptosporidium has a high tolerance<br />to chlorine and can survive in a<br />chlorinated pool for up to seven days. The parasite enters the body through<br />ingestion of contaminated water. Between 2009 and 2017, 7,465 people<br />fell ill due to outbreaks, with recreational<br />water responsible for a third of the outbreak cases. CDC, via statement Although it is considered to be almost<br />never fatal, one death was reported in 2009<br />and 287 people have been hospitalized.
