23 sick: Cryptosporidiosis outbreak in Illinois linked to 4-H projects

The Clark and Champaign county health departments say they’re investigating 23 possible cases of cryptosporidiosis linked to dairy calves brought to the region for youth 4-H projects. 

The calves were sold to children.  A Clark County epidemiologist says hydrogen peroxide is the only known disinfectant for killing the parasite. No other information has been released.
