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.
