The document describes a "Break the Chain" social marketing campaign launched by the Kerala health ministry in India to promote hand washing and other hygiene practices to prevent the spread of COVID-19. The campaign uses social media platforms to raise awareness of the importance of personal hygiene, like frequent hand washing with soap and water, in order to break the chain of virus transmission within communities. Kerala has been able to minimize virus spread so far through early surveillance and public support of measures like hand washing promoted by the "Break the Chain" campaign.
