April 2020 – Page 2 – An Echo That's Reversing

Coronavirus – Sat 11 Apr 2020 – Stultification

I realized I hadn’t written in a week or so. I need to witness for myself and I’m not really sure why I paused. Maybe the stories start feeling all the same? Trump catastrophe after Trump catastrophe? Maybe we’ve settled in and a pandemic is boredom? That’s wrong: the weekly offenses are unique and my experiences are unique.

Catastrophes mount, this is Sat 11 Apr 2020:

Unemployment, rescue, bailout

Chart from an NYT article showing our current possible unemployment rate (numbers come in later) with previous back to 1930:

Asymptomatic, pre-symptomatic, subclinical

Georgia Gov. Brian Kemp says he didn’t know asymptomatic people could transmit coronavirus from Newsweek, 2 Apr 2020

Individuals could have been infecting people before they ever felt bad, but we didn’t know that until the last 24 hours.

As shocking as his lack of knowledge on a pandemic that is changing the world society is, it’s important to note: “symptomatic” is to a degree subjective. Some people have higher base temperatures, are they symptomatic? Some cough regularly. Some have IBS. Unless there is an obvious degradation of health, there is really no well-defined checklist of factors to make someone symptomatic. So when is it safe to allow widespread personal integration and travel? I’m going to be an asshole and quote myself:

Viruses that show symptoms faster and that kill their hosts faster will have a more limited spread. COVID-19’s delay and lower fatality rate may be making it more widespread.

Here’s the timeline knowledge on transmission as best as I could find (I will updated if I get better info):

Masks, airborn, crowds

A really good overview on the current understanding of airborn risk and usefulness of masks:

Everyone Thinks They’re Right About Masks from The Atlantic

Long (and def worth a full read), but summary points:

“Aerosol” distribution can mean either heavy droplets or mist. No solid answers to the risks of either. Studies still ongoing and may not be answered for years.
Presence of aerosol-distributed COVID-19 does not necessarily mean risk since the existence of RNA “is like a fingerprint” in that it means the virus had been present, but may no longer be.
Even the most crowded sites in Wuhan had <12 particles per meter^3. SARS takes 43-280 for infection.
Safest: go outside for fresh air but stay out of even small crowds or small spaces with others, open your windows every now and then.
Surfaces still the primary risk.
Utility of masks also has no solid answers. Homemade masks (shirt, towel) can block 69-83% of particles. Best possible use currently is to protect others from you.
The science is moving (necessarily) quickly and so advice is also. Be wary of pop science headlines.

Q&A: Masks and COVID-19 – What is WHO’s view on masks?

Aside from medical masks for health professionals and those at risk, WHO recommends cloth masks only in high infectious areas and crowded or enclosed spaces:

Non-medical, fabric masks are being used by many people in public areas, but there has been limited evidence on their effectiveness and WHO does not recommend their widespread use among the public for control of COVID-19. However, for areas of widespread transmission, with limited capacity for implementing control measures and especially in settings where physical distancing of at least 1 metre is not possible – such as on public transport, in shops or in other confined or crowded environments – WHO advises governments to encourage the general public to use non-medical fabric masks.
