MILWAUKEE, Wis. - Health officials confirm several cases of an illness caused by the waterborne parasite cryptosporidium in northern Milwaukee suburbs.
The North Shore Health Department says eight cases of cryptosporidiosis are confirmed in Bayside, Fox Point and Whitefish Bay, and there are also 12 probable cases.
Both children and adults have been affected.
Health officials say the crypto source is not drinking water, but they are looking at pools and lakes.
WISN-TV (http://bit.ly/1awtl9e ) reports children at two schools were sent home with letters because students had the illness.
The health department says the cases first started being reported in early September.
Symptoms include stomach cramps and diarrhea.
In 1993, the parasite entered Milwaukee's municipal water supply, leading to the deaths of as many as 100 people and sickening hundreds of thousands more.
