As part of the LessWrong Coronavirus Link Database, I am publishing a daily update post with all the new links we are adding each day that we ranked a 3 or above in our importance rankings. Here are all the top links we (Elizabeth, Ben and I) added over the weekend, by topic.


Coronavirus: Why you must act now (medium post)

Summary and call to action, one of the best summaries I've found, focuses more on policy-interventions than on individual actions, but is still good at giving you an overview

UpToDate: Coronavirus Overview

UpToDate very frequently has the best overviews over many crucial medical topics. Geared towards a more professional medical audience. 

Letter to loved ones asking to take CV seriously

Well written, compassionate explanation of why this is worse than what we've seen before and need to take this seriously. A few pointers on where to get started

Metareview: facemasks at mass gatherings 

A collection of 25 studies with 12710 participants was examined. Out of 13 studies on respiratory illness, 4 showed statistically significant effectiveness, 1 showed statistically significant ineffectiveness, the rest produced no statistically significant results

“Flattening the Curve” is a deadly delusion

At current medical capacity, we'd need to flatten the curve for 10 years in order to get everyone full treatment

Summary of papers arguing that many/most infections spread from people before they show symptoms

A readable summary of some papers about how quickly people transmit the disease and how quickly the symptoms show. Argues that perhaps the majority of people transmit it before they show symptoms.

Timothy Gowers: Herd immunity is very costly, and we can't get all the things we ant

Rob Wiblin: Model update suggests we are dealing with unmitigated exponential growth

Rob Wiblin updated his spreadsheet model with new data, which suggests that we are basically dealing with unmitigated exponential growth, without any significant slowdown


Twitter: CV kills via cardiac failure, not pulmonary

Apparently the ARDS is not too severe, and they can manage people through that part of it. Instead, after several days, the virus suddenly attacks the heart, causing it to precipitously fail. The myocarditis phase is savage and kills people within a day or two

Estimate of C19 death rate

Tries to produce more accurate death-rate estimates for China, South Korea, and Italy, based on interpretation of existing data

Seattle ICU Dr describes CV progression

The Chinese data on 80% mildly ill, 14% hospital-ill, 6-8% critically ill are generally on the mark,  elderly patients going to "comfort care", detailed description of clinical presentation, remdesivir is scarce

Doctor reports 20-30% reduction in lung capacity in 1/4 of patients

News report on a doctor saying that 2 or 3 out of 12 patients have seen a 20-30% reduction in lung-capacity and "They gasp if they walk a bit more quickly"

Medical System

Twitter: Seattle approaching Lombardy levels

Seattle has ventilators but is out of ICU beds. Due to a lack of machines, Seattle is restricting ECMO machines to people <40 yo and < 25 BMI. Most people are dying of heart, not lung, issues

Twitter: Seattle ICU Dr describes conditions in Seattle hospital

Entire ICU taken up by CV patients, CDC is weakening quarantine on medics, they are out of masks in part because people are stealing from them

Jess Riedel's Fermi Estimate that not containing coronavirus will overwhelm UK medical system

Jess Riedel's Fermi Estimate that not containing the coronavirus will overwhelm the UK medical system


Coronavirus case dashboard

Very comprehensive dashboard with dozens of graphs. Currently the best resource I know for tracking both national and global spread.

Aggregators Coronavirus page

Surprisingly high-quality of articles on the Medium coronavirus page. 


Effective Altruism Facebook group on Coronavirus discussion

Twitter: Seattle approaching Lombardy levels

The claims in that Twitter thread (now deleted) have been retracted:

Great! Thanks for the update! Will update the spreadsheet.

Is there an easy way to follow these daily updates or the corona virus tag i can recommend to people who don't frequent LessWrong?

We don't yet have subscription functionality for tags, sadly. I am probably not going to create many non-coronavirus posts for the next few days/weeks, so subscribing just to posts by me should get them basically just these summaries. (To do that, click on the triple-dot at the top of the post when you are logged and select "Subscribe to posts by habryka")

It doesn't look as if the dashboard includes the United States on many of the pages.


Regarding the Rob Wiblin model, is it possible that the conclusion (though I suspect is based on global numbers) is due to local epicenter events and so not necessarily something that should be generalized without some caveats?
