NORTH SHORE (WITI) -- Health officials are still trying to pinpoint the source of a cryptosporidium outbreak. It is blamed for making at least 20 people sick on Milwaukee's North Shore. The outbreak was announced on Friday, September 27th -- and the good news is that since then, we have seen no new cases.
After chemical treatment with high levels of chlorine, the Whitefish Bay High School swimming pool reopened on Monday.
The North Shore Health Department did not find a link to illnesses there, but the treatment was done as a precaution.
Dick Yahr went swimming at the Whitefish Bay High School pool on Monday -- despite the fact that he has had personal experience with crypto.
"I survived the crypto epidemic in Milwaukee where 400,000 people got sick. I was sick for 52 days and I didn't know if it ever was going to leave. I'm so grateful it was done," Yahr said.
On Sunday night, the Whitefish Bay School District sent out a phone system message to parents, saying: "Our schools will continue to cooperate with the North Shore Health Department as they investigate the point of origin in the North Shore community."
At least two cases of illness involved children at Cumberland Elementary School in Whitefish Bay. On Monday, Kendall Bryant arrived at the school to pick up his nephew, who wasn't feeling well.
"It's sad that he got sick today. We just got to find out what the problem is. He was fine this morning and he was fine last night, so today we just gotta figure out what the problem is," Bryant said.
The North Shore Health Department said Monday: "No individuals have been hospitalized from crypto. The source has not been identified."
The North Shore Health Department says it continues to focus on recreational water facilities. Officials say the drinking water is safe.
The Health Department urges people who feel sick with stomach problems to get tested.
