There is an aggressive debate going on whether cloth masks are necessary. Are they meant to protect you from getting the virus? COVID-19 spreads when an infected person coughs, sneezes, or talks through respiratory droplets. These droplets land in the mouths or noses or get inhaled by others who are in the vicinity. Cloth face coverings are a simple barrier, preventing the spread of respiratory droplets. Rather than preventing you from inhaling these droplets, they stop you from unleashing them. Rather than protecting the wearer, they limit the risk of others around them.
People are opposing the idea of masks but why? From simple freedom to the thought that this is pandemic is a conspiracy and medical reasons to not wear a mask. People have been on sides like this in our past. Going back into the 20th century which was not that long ago we saw similar debate with the adoption of seat belts.
