Today I ran across a video by Dr. Duc Vuong . He is a weight loss surgeon in the US. While he may not specialize in epidemology, he explains COVID-19 and the pandemic in simple enough terms for anyone to understand. His language is a little strong and some of his choice of analogies sometimes questionable, but the videos get the point across.
Vuong recorded the first video below in March 2020, explaining how COVID-19 attacks the body and eventually kills people. Also in the video he made predictions about rates of infection in the US, India and elsewhere over the summer. His numbers were not exact, but his prediction of trends was.
More below the fold.
