COVID-19: The Effectiveness of Free Face Mask Distribution

The investigators will carry out a randomised trial of free face mask distribution in Stovner District, Oslo, Norway. Ten grocery stores will serve as study sites. Over three weeks the stores will be randomised daily to having "corona hosts" outside their entrance, handing out face masks to customers. The investigators will compare the proportion of customers who wear face masks as they enter the store in stores with or without face mask distribution.
