    Warning: Wearing a non-medical mask in the community has not been proven to protect the person wearing it from being exposed to or contracting the Covid-19 virus. It is, rather, an additional measure you can take to protect others around you. Strict hygiene and public health measures, including frequent hand washing and physical (social) distancing, will reduce your chance of being exposed to the virus.
