The education ministry on Tuesday issued guidelines to reduce the risk of coronavirus infection in schools that are scheduled to reopen in April after monthlong closures, calling for thorough ventilation of classrooms and warning against gathering in clusters.

The guidelines also request that students and staff avoid conversing with others at close quarters, check their body temperature frequently and wear face masks.

If an infection is confirmed, the infected individual and those who were in close contact are to be suspended, according to the guidelines. Temporary closure of classes or the entire school will also be recommended.
