It's my school's Autumn and Winter preparedness.

This school's vaccination team reminds us:
Because of the number of high-prevalence risk sites, it is impossible to list them all.
The rule is "uneasy to maintain social distance, close to the inside of a person" and should be covered by a mask.

The health and cough rituals should be maintained, including the fever and the cough conditions, and should be used to inform health education units, school-based centres and to provide preventive measures.
