Determinants of COVID-19-related knowledge and preventive behaviours among students in reopened secondary schools: cross-sectional study.

Significant number of the students had inadequate knowledge about COVID-19 and poorly engaged in COVID-19 preventive behaviour. Thus, it is suggested to include and disseminate about COVID-19 in related academic sessions, using school clubs and minimedias. The sources of COVID-19-related information need to strengthen the dissemination of tailored, credible and timely message to enhance the knowledge and engagement of the students in preventive behaviours.
