masks

There is a distinction between healthy concern for the coronavirus and deeply unhealthy obsession and paranoia. Guess which side Esquire magazine picked?
Much remains biologically uncertain about COVID-19, especially when it comes to its infectiousness. For example, how many particles must be taken to allow the virus to begin to replicate within oneself? On the other hand, the virus particle itself is subject to well-established laws of physics. So, when it comes to masks and social distancing, how can physics inform our understanding? Let's take a look.
Researchers in the journal Physics of Fluids  just published a visualization of the dispersion of droplets from simulated coughing. It's worth a look.
It was a bad idea last month; why publish it again? Mandating flu vaccine for healthcare workers is a no-brainer, the arguments against it are specious. So why did JAMA re-publish the article endorsing masks instead? They protect no one except fearful workers from imaginary dangers, while exposing patients to contagion.
As the federal government shuts down, some CDC and FDA functions will be compromised, and some threat to public health may arise. A JAMA op-ed piece approves of vaccination OR masks for healthcare workers. We disapprove.
