Key Message
A cross-sectional study carried out on high school students during the second surge of COVID-19 in Indonesia revealed that they benefitted from the COVID-19 module. Students who viewed the module had higher scores on health literacy measures of adolescents (HELMA), had a more favorable attitude toward government-issued restrictive policies, and were more likely to have adequate health literacy, in regard to the ability to use health information. These imply schools as part of the public health response by providing education to increase adolescents’ health literacy and the public’s support for health initiatives to prevent and limit the spread of COVID-19.
