LONDON, Ohio (AP) _ An outbreak of a highly contagious skin infection called impetigo has canceled all classes in a central Ohio school district. 

Superintendent Tim Dettwiller tells WBNS-TV (http://bit.ly/1ht93pA) about 60 students showing signs of the infection were sent home Thursday from the Madison-Plains district in London, west of Columbus.

Classes were canceled Friday, though weekend athletic events were set to proceed as planned despite the outbreak. The superintendent said a crew would be cleaning the school buildings.

Impetigo is an infection that mainly affects children and causes red sores, especially on the face around the mouth and nose. It can clear up on its own after a few weeks or with treatment from antibiotics.
