Some 40 people have fallen ill after being infected by Cryptosporidium, reports Skovde News.

It is associated with kosläpp, a Hjo and one in Skövde, two outbreaks occurred in May.

Infectious disease doctors in the area now warning parents to let young children petting calves at kosläpp and immediately afterwards eat food or refreshments, writes Skovde News. Then they risk getting upset stomach with abdominal pain and diarrhea.
