Do masks work? Arguments pro and con published today

by Guy Page

Since last March, Vermonters have debated the most fundamental Mask Question: do they prevent transmission of Covid-19?

Today, in an effort to transmit useful information and stimulate fact-based public discussion, Vermont Daily presents two opposing perspectives.

Arguing the “pro” side of mask effectiveness, the CDC on November 20, 2020 published “Science Brief: Community Use of Cloth Masks to Control the Spread of SARS-CoV-2.” It is published separately on Vermont Daily today, and also can be read in entirety by clicking on the headline link. Main points:

  • “SARS-CoV-2 infection is transmitted predominately by respiratory droplets generated when people cough, sneeze, sing, talk, or breathe.”
  • Masks are primarily intended to reduce the emission and inhalation of virus-laden droplets (“source control”).
  • Masks are not foolproof: “Multi-layer cloth masks can both block up to 50-70% of these fine droplets and particles and limit the forward spread of those that are not captured.”

Taking the “con” position is Aaron Warner of Hartford, a boxing instructor and Cardiovascular Fitness Specialist and Cardiovascular Performance Specialist with the National Academy of Sports Medicine. He argues in “Masked to Death,” published today in Vermont Daily, that masks do little demonstrable good but can do harm:

  • there is a lack of reliable Random Controlled Studies (RCT) showing that masks prevent transmission in community and hospital settings
  • Danish and Chinese studies show no transmission through asymptomatic people
  • Broad use of masks, especially when exercising is linked to hypoxia (lack of oxygen delivered to the vital tissues of the body), hypoxemia (lack of oxygen available in the blood stream), headaches, and difficulty breathing.

Readers are invited to ask comments and questions. Both Warner and CDC and/or VT Dept. of Health experts will be asked to follow up, as needed.

  1. Most of the exhale fogs up my glasses, then I can’t see and walk out in the road and get hit by a bus and my mangled buried body cannot spread the virus anymore… so masks work on not spreading the virus especially after you get hit by a bus.
    Masks only work to make people angry scared and think this virus is more than just a common cold for 99.98% of the population.
    (See attached article) If you look at the graphs of Florida least restrictive measures compared to the lunacy in CA & NY, you’ll see that the masking did not work for CA & NY.

  2. We need to get back to work tomorrow and forget about face masks,social distancing,and the flu;we have lives to live,dreams to fulfill;Life, Liberty, and the pursuit of happiness through hard work!!Oh,and turn off your TV,most of the news media are paid propaganda personalities to tell you what to think and divid and fill many with fear!!
