Connecticut’s Education Commissioner Miguel Cardona said there is no sign of transmission of COVID-19 within schools. When contact tracers look for the source of a student’s illness, Cardona says the cases appear to have originated outside of school. The commissioner says if the illness was spreading within schools, multiple cases would be seen in classrooms or other groups of students that spend time together, but that has not been observed. There have been more than 450 student cases. But Cardona says almost a hundred of those students were learning from home, and did not regularly go to school. Cardona appeared on Connecticut Public Radio’s Where We Live Monday.
