Schools and day-care centers are preparing strong COVID-19 infection prevention controls.
With them in place, they hope to have low levels of virus transmission, reports CNN.
Recently, seven schools and daycare centers underwent antibody screening, symptom surveys, and testing.
The child-to-child transmission rate was found to be 0.3%.
However, the child-to-staff rate was 1%, and staff-to-child transmission rate was 1.5%.
Even worse, the staff-to-staff was 4.4%.
