> If parents must work and grandparents must become the primary caretakers of children, the risk significantly increases that these persons, who are per se at the greatest risk of serious illness, may become infected, and this is what happened in Italy in the first 2 weeks when school closure was decided but other work activities were not stopped.

And the WHO just said today that asymptomatic people are very unlikely to transmit the disease.

My big problem with schools making decisions now is there are too many unknowns, and the situation is too fluid. They really need to wait another month, month and a half.
