A Study Shows Masks are Extremely Effective at Preventing Virus Spread

New research shows that masks are extremely effective at preventing the spread of CoVID-19. Previous research focused primarily on masks preventing the spread of the flu rather than CoVID-19. The new study tested the effectiveness of surgical masks at preventing the spread through droplets aerosolized particles.

“…surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals.”

The study found that CoVID-19 was detected in 30- 40% of particles in aerosols and droplets expelled by those not wearing a mask. However, no virus was detected in aerosols or droplets from those who wore a face mask.

Despite research indicating that wearing masks could prevent the spread of the virus, the CDC has not recommended that everyone wear N95 masks. Alternatively, they recommend that N95 masks are saved for healthcare personnel only. Currently, the CDC is recommending homemade/alternative masks that are not N95 masks, and recommending social distancing and handwashing instead of N95 masks.

A surgical N95 (also referred as a medical respirator) is recommended only for use by healthcare personnel (HCP) who need protection from both airborne and fluid hazards (e.g., splashes, sprays). These respirators are not used or needed outside of healthcare settings.”
