The Internet Book of Critical Care is an online textbook written by Josh Farkas (@PulmCrit), an associate professor of Pulmonary and Critical Care Medicine at the University of Vermont.
This online source is highly technical and written for Emergency Medicine specialists. I only know about this source because of Project #1. But if you’re interested in a deep dive into Covid-19 this website offers fascinating reading.
My #1 takeaway:
It remains unclear what fraction of patients are hospitalized.
There may be lots of patients with mild illness who don’t present to medical attention and aren’t counted.
The vast majority of infected patients (e.g. >80%) don’t get significantly ill and don’t require hospitalization.
Stay calm.
