A recent report from the Centers from Disease Control (CDC) shows the number of Cryptosporidium or Crypto has increased in the United States. 

According to the CDC report, researchers saw a 13% increase in Crypto cases from 2009 to 2017. 

It's an illness people can get from swallowing contaminated water.

Lowe Wilkins, Program Manager with the Chattanooga-Hamilton County Health Department said people who are sick need to stay out of pools.

"If they go to a pool at that time, a public pool or their own private pool and they have diarrhea and that enters the pool that that parasite is in the pool," Wilkins said. "Anyone else in the pool, if they got water in their mouth than at that point they would be exposed to the parasite."

While the CDC report shows the number of cases has increased in the U.S., Wilkins said the numbers in Hamilton County have decreased in the past few years. 

In 2019 so far, the Chattanooga-Hamilton County Health Department has had one reported case of Crypto, according to Wilkins. 

Here are the other numbers of Cryptosporidiosis, according to a report on the Chattanooga-Hamilton County Health Department's website:

Hamilton County Reportable Diseases 2012 2013 2014 2015 2016 2017 2018
Cryptosporidiosis (cases reported) 7 3 3 7 10 13 9

The health department is in charge of inspecting more than 300 pools in Hamilton County to make sure the pool employees are taking proper procedures, especially if there is an accident in the pool. 

"We ask people basically to immediately exit the pool and super chlorinate the pool and go through a process of cleaning that immediately," Wilkins said. 

Wilkins encourages parents to make sure their children have water diapers on while swimming. 

CDC suggests not to swallow water while you swim and to make sure you wash your hands with soap and water.
