The incidence of COVID-19 for school-age children (6-18 years) in West Java was recorded at 6.8% of the number of positive cases (143,043 cases as of August 18, 2020) which decreased after the government implemented online learning to 42,330 cases. COVID-19 cases in children rose again by 15% as of August 2021. Children and adolescents are at risk of exposure from confirmed family members, close environments or outside the home where children and adolescents carry out activities. Adolescence is a period of transition from childhood to adulthood, at this time an individual has not been able to be responsible, both to himself and to society. This is one of the risk factors for the increasing incidence of COVID-19 in children and adolescents. The purpose of this community service is to increase the knowledge and attitudes of the youth of the Mathla'ul Huda mosque through health education with video media in an effort to prevent COVID-19. The community service was attended by 36 teenagers from the Mathla'ul Huda mosque who were expected to become agents of change in preventing COVID-19.
