Scientific Research Supports Universal Masking

• CDC and WHO both recommend that all people wear masks in public.
• Face masks, combined with hand-washing and social distancing, are scientifically proven to slow the spread of Coronavirus by reducing airborne transmission of infectious droplet and aerosol particles (smaller droplets).
• Universal masking results in the lowest transmission rates from infected symptomatic and asymptomatic individuals to healthy populations.
• Recent study published in Nature Medicine found that people infected with Coronavirus who wore surgical masks did not shed the virus in respiratory droplets or aerosols, while 30%-40% of those not wearing masks did shed the virus.
• Study by Hong Kong University of Science and Technology found that if 80% of the population wears a high-quality non-medical mask when lockdowns end, combined with social distancing, the virus could be eliminated. This scenario would result in 25% of the expected deaths compared to the deaths expected when only 50% wear masks.
• Arizona State University scientists found that if 80% of people wore only moderately effective masks, it could reduce the number of deaths in New York by as much as 45% over a 2-month period. Even wearing masks that were only 20% effective could cut mortality by up to 65% in Washington.
