Are Masks 100% Effective?
The gold standard N-95 mask is 95% effective at keeping the wearer free of inhaling viral particles. These masks are still best reserved for front-line workers in high risk settings where aerosols of viral particles occur. Surgical masks are less effective and cloth face coverings even less so in protecting the wearer. However even a 50% reduction in viral transmission is statistically important.
For the general public, the reason for wearing a facial covering is to help protect others from you when you cough, sneeze or even talk and spray viral droplets into the air. Many people who become infected can unknowingly spread the COVID-19 virus because they have few or no symptoms. So wearing a mask is showing respect for others and is your way of helping lessen the spread of the disease. It is important that the mask not be so thick as to make breathing through them completely uncomfortable. Filter inserts are probably not necessary and may make the masks more uncomfortable.
"Mask wearing allows us to open the economy up faster. Not wearing a mask around others only worsens the pandemic, leads to more disease, and worsens the economic effects."
