BEND, OR -- None of the teenagers who attended Super Bowl weekend parties that led to an outbreak of virus cases at Summit High School were symptomatic. Health Officer Doctor George Conway told county commissioners being asymptomatic, the teens may have exposed elderly or medically fragile relatives to the virus who could become very ill. Conway also urged asymptomatic teens who attended those parties to go to a public testing event to be announced in the next day or two. So far 43 virus cases have been reported at Summit High and at least one case at Bend, Mountain View and Skyline High Schools.
