The Science Behind Masks

The Science Behind Masks

As our states have been reopening slowly, there has been an increase in Coronavirus cases. As of to date, there have been 11,948 cases in the state of Oklahoma according to the State Health Dept. 

An article from the University of California San Francisco say, health experts say there is clear evidence that masks can help prevent the spread of COVID-19. Studies have found that viral load peaks in the days before symptoms begin and that speaking is enough to expel virus-carrying droplets. One category of evidence comes from laboratory studies of respiratory droplets and the ability of various masks to block them. An experiment using high-speed video found that hundreds of droplets ranging from 20 to 500 micrometers were generated when saying a simple phrase, but that nearly all these droplets were blocked when the mouth was covered by a damp washcloth. A recent study published in Health Affairs, for example, compared the COVID-19 growth rate before and after mask mandates in 15 states and the District of Columbia. It found that mask mandates led to a slowdown in daily COVID-19 growth rate, which became more apparent over time. The first five days after a mandate, the daily growth rate slowed by 0.9 percentage-points compared to the five days prior to the mandate; at three weeks, the daily growth rate had slowed by 2 percentage-points.

Three W’s to ward off COVID-19:

  • Wearing a mask 
  • Washing your hands
  • Watching your distance

Stay safe and be mindful of yourself, community, and state to wear a mask so we can end this pandemic together!
