Religious school retreat led to coronavirus outbreak in Wisconsin

The coronavirus tore through a religious school retreat in Wisconsin over the summer, fueled by a lack of proper mitigation measures. Although nobody fell seriously ill, the scope of the outbreak — an exceptionally high 76 percent infection rate — suggests the intensity with which the airborne pathogen can proliferate in the absence of appropriate measures.

The outbreak is discussed in a new study published on Thursday by the Centers for Disease Control and Prevention. The CDC does not name the camp in question, describing it only as a “faith-based educational retreat for boys in grades 9-11” in Wisconsin.
