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.
COVID-19 has exposed fault lines in our healthcare system, often problems that physicians and nurses have been pointing out, to no avail, for years. New York City's mayor announced a plan to modify grading due to COVID-19 ignoring the fact that many of the school's graduates have significant functional illiteracies. The courts in Michigan are finally stepping up to address the real issues. Miasma is responsible for COVID-19's infectability.
