Description: Resources for COVID-19

Novel Coronavirus General Info

Items marked NEW→ are recent additions to this file.

An ad hoc and unofficial collection of resources. I live in Illinois, so I'm including Illinois-specific resources. - Hal



The disease: COVID-19 - coronavirus disease.

The virus: SARS-CoV-2 - severe acute respiratory syndrome coronavirus 2.


Three public health terms

See "Impact of non-pharmaceutical interventions (NPIs)..." and "The Hammer and the Dance" below for use of these terms.

anosmia: loss of sense of smell

  • also hyposmia, reduced ability to smell things

ageusia: loss of sense of taste

  • also hypogeusia, reduced ability to taste things

NOTE: 2020-03-21 ENT UK: Loss of sense of smell as marker of COVID-19 infection (slow link)

there have been a rapidly growing number of reports of a significant increase in the number of patients presenting with anosmia in the absence of other symptoms

Two Purposes for Masks

NEW→ Thanks to Carl T. Bergstrom (see twitter feeds below) for this clarification. Wording here is from Bergstrom's 2020-04-03 thread.

receiver protection: your mask protects you from others. A properly fitted N95 provides effective receiver protection, but fitting is very difficult and not easily achieved by members of the public without training and equipment.

source control: your mask protects others from you. A basic surgical-type face covering provides effective source control.

Personal Protective Equipment (PPE)

CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies) especially in areas of significant community-based transmission.

  • 2020-04-02 This graph (from #covidly) shows the relation between “incidence” of new case and “cumulative cases” and a way my profession judges how good or bad it is going. The US at the top right shows today we are losing the battle faster than any other country. This is not way to be great

    Tonight #DeborahBirx stated that models anticipating large-scale transmission of COVID-19 do not match reality on the ground...

    It is a fundamental scientific error to take the current success of containment in some places as a sign that permanent containment is possible. We should work to make it possible, but 1918 flu and, frankly, the germ theory of disease show that containment is a temporary victory

    Here is how it looks in practice. Most of my childhood friends are now doctors working in north Italy. In Milan, in Bergamo, in Padua, they are having to choose between intubating a 40-year-old with two kids, a 40-year old who is fit and healthy with no co-morbidities, and a 60-year-old with high blood pressure, because they don't have enough beds. In the hallway, meanwhile, there are another 15 people waiting who are already hardly breathing and need oxygen.
