Why masks lower COVID-19 deaths

Masks aid in decreasing COVID-19's virality by three pathways 8.

Decreasing virus spread by infected individuals. The mask traps virus particles on the inside, preventing the virus particles becoming airborne. Protect others. Decreasing new infections by uninfected individuals. The mask prevents airborne virus particles being inhaled from the outside. Protect yourself. Limiting hand to face contact. The mask puts a physical barrier between potentially contaminated hands and passages to one's lungs.

We need to increase these virality-decreasing pathways by encouraging a universal mask-wearing protocol to fight COVID-19.
