Medical masks are surgical or procedure masks that are flat or pleated (some are like cups); they are affixed to the head with strapsa. Wearing a medical mask is one of the prevention measures to limit the spread of COVID-19 amongst people although it doesn't 100% prevent one from contracting the virus. It is entirely important to keep a face mask on especially when in crowded places or around people to prevent the spread of the virus.
In public health, social distancing, also called physical distancing, is a set of non-pharmaceutical interventions or measures intended to prevent the spread of a contagious disease by maintaining a physical distance between people and reducing the number of times people come into close contact with each other.
Using a hand sanitizer decreases microbial counts and eliminates viruses that you may have contracted on your hands including COVID-19. In order to keep safe from the virus, it is important to sanitize your hands before and after touching anything in order to avoid contracting the face.
