Wearing a mask may not ensure your safety, but it does highly reduce the risk of you catching COVID-19. Also, it can keep others safe, in case you are unknowingly infected. You may not get COVID-19, despite not following all the safety guidelines, but if you do, the chances will be reduced for both you and those around you. So please, if you do not already, wear a mask, social distance, etc. It isn't that much effort, and it's worth it.
