Health workers are asking the Americans to take precautionary measures against reports that the "crypto", fecal parasite that can be passed over the pool, is on the rise.
A lot of parasites Cryptosporidium. This causes cryptosporidiosis, which can leave healthy adults suffering from "abundant, watery diarrhea" for up to three weeks. Effects may be worse for children, pregnant women and those with compromised immune systems.
"The number of treatment-related recreational epidemics caused by cryptosporidium causes peak summer season and in cryptosporidiosis and cryptosporidiosis as a whole," said the American Center for Disease Control and Prevention.
Although almost never fatal, one death has been reported since 2009, according to the CDC. More 287 people were hospitalized between 2009 and 2017, according to CDC.
The CDC report released on Friday explains why healthcare workers are upset:
- Between 2009 and 2017 there were 444 episodes of cryptosporidiosis in 40 states and Puerto Rico.
- The outbreaks resulted in illnesses of 7,465 people.
- Recreational water – mainly swimming pools, as well as swimming pools and water playgrounds – are responsible for 156, more than a third of cases.
- Untreated water (such as lakes) and drinking water have caused another 22 cases.
- Eighty-six cases involved contact with animals, mainly cattle.
- The other 57 cases were related to the conditions for keeping children.
- Twenty-two cases were transmitted to food, most of which included unpasteurized milk or apple cider.
- Most cases were recorded in July and August, and 2016 was the culmination of an outbreak of more than 80 diseases.
- The number of cases increased by an average of 12.8% per year between 2009 and 2017.
The CDC adds two alert numbers, which are suspected of underestimating the number of real cases and epidemics: a sudden increase in cases may be the result of new testing technology, and the requirements and the ability to detect, investigate, and report cases vary by jurisdictions.
It is also worth mentioning that one death from cryptosporidiosis came in the only instinct where the parasite was transferred to the hospital.
In pools, cryptosporidium can enter the body when the swimmer swallows contaminated water.
Parasites are a problem in swimming pools because an infected swimmer can extract parasites in several queues in excess of the amount needed to induce an infection. Cryptosporidium has high chlorine tolerance and can survive in a properly chlorinated pool for up to seven days, says CDC.
There are preventive measures that can help stop the outbreak of the disease, and the CDC works to educate the public about them.
Young patients with diarrhea should not be placed in childcare according to the CDC, and after the crypto-stigdomio outbreaks, childcare workers need to clean the surfaces with hydrogen peroxide because the chlorine bleach is an ineffective way of killing the parasite.
People who come into contact with the stock should thoroughly wash their hands and remove all shoes or clothing to avoid contamination of other environments, such as their homes.
As for the pool, anyone who suffers from diarrhea should avoid swimming for at least two weeks after reducing the diarrhea, says CDC.
The latter is most important because 24% of Americans say they would jump in the pool within an hour of diarrhea, according to a study released last month by the Council on Quality and Health of Water.
