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.
