Let’s consider the principles of masks to reduce viral spread

What are masks? Are they immunological interventions? Obviously not. Are they medical interventions? No. Are they virological interventions. No, antiviral drugs are virological interventions. Then what kind of intervention are masks? They are physical interventions aimed at having an epidemiological impact, because the hope is that they reduce viral spread. So, masks being physical interventions,Continue reading “Let’s consider the principles of masks to reduce viral spread”

I review a mask study published in the Journal of the American Medical Association (JAMA) from a physics perspective

Here’s the study. The authors are a couple of MDs. let’s look at their spiel. “COVID-19 spreads primarily through respiratory droplets exhaled when infected people breathe, talk, cough, sneeze, or sing. Most of these droplets are smaller than 10 μm in diameter, often referred to as aerosols.” “Most are smaller than 10 microns in diameter….”Continue reading “I review a mask study published in the Journal of the American Medical Association (JAMA) from a physics perspective”
