Update: We just launched a new version of our link database. We now have over 350 links categorized in total, and the database is now properly integrated into LessWrong and even works on mobile!
As part of the LessWrong Coronavirus Link Database, Ben, Elizabeth and I are publishing update posts 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 that we added over the last two days (March 22nd and 23rd), by topic.
(RS) Interesting to see general day to day activity and response to international news from the Chinese mainland perspective. Lots of thought provoking questions being discussed.
Two approaches to calculating how much the money lost from the economy due to shutdowns could have saved lives
(EV) Starts with the current death count, no projected uncontrolled death count, which is a terrible sign. Leaves out lives saved for non-C19 reasons from shut downs (via e.g. polllution and reduced driving)
Society for Critical Care Medicine’s newly conducted census of US ICU beds, vents, and other medical resources. Staffing strategies to cope with overload
This is a specification of the minimally (and some preferred options) clinically acceptable ventilator to be used in UK hospitals during the current COVID-19 pandemic caused by SARS-CoV-2 virus. It sets out the clinical requirements based on the consensus of what is ‘minimally acceptable’ performance in the opinion of the anaesthesia and intensive care medicine professionals and medical device regulators.
Fairly substantial amount of literature covered by a Human Biology PhD. Key takeaway: “Melatonin appears to reduce exacerbated immune responses by lowering production of pro-inflammatory cytokines including IFN-gamma and IL6 which are responsible for inflammation in the lung and loss of function during ‘cytokine storm’ a feature of COVID19. This is found in both animal studies and in human studies.”
Pre-print says that those with type A blood are more likely to test positive in a hospital (implying hospitalization?) than B or AB, who are in turn more likely than those with type O. All differences were statistically signficant but modest

Virologist explains why vaccine may be possible
Virologist/investor explains why people are unnecessarily pessimistic about creating a vaccine for C19.
Standards for a minimally acceptable ventilator
This is a specification of the minimally (and some preferred options) clinically acceptable ventilator to be used in UK hospitals during the current COVID-19 pandemic caused by SARS-CoV-2 virus. It sets out the clinical requirements based on the consensus of what is ‘minimally acceptable’ performance in the opinion of the anaesthesia and intensive care medicine professionals and medical device regulators.
Review of evidence around chloroquine
Summarizes all available evidence around chloroquine and finds it worth further study but not particularly established.
USArmy Engineers have plans for fast creation of new medical facilities, starting to act
US Army plans to create field hospitals out of existing structures (e.g. hotels) and initial action in NY.

Summary of Metaculus Covid19 Forecasts
Goes through the main predictions, showing how they changes over time.
Progression & Outcome
Half of patients reported to hospital with digestive issues as their chief complaint
84% of digestive cases reported anorexia, 29% diarrhea. 3.5% of patients had digestive but no respiratory symptoms
Loss of smell an early indicator of C19?
Several doctors anecdotally report a lot of patients presenting with loss of sense of smell (anosmia).

Flattening the curve is shrinking the curve
Basic SIR models demonstrate that flattening the curve (by shrinking R0) also shrink the total number of people infected
Estimates prevalence by looking at exports
Estimates C19 prevalence using data from countries that check travelers at the border
Can we conserve tests by pooling?
In a world where most tests are negative, you could pool samples and test them together to get results for more people
Lit Review on Melatonin As Covid Treatment
Fairly substantial amount of literature covered by a Human Biology PhD. Key takeaway: “Melatonin appears to reduce exacerbated immune responses by lowering production of pro-inflammatory cytokines including IFN-gamma and IL6 which are responsible for inflammation in the lung and loss of function during ‘cytokine storm’ a feature of COVID19. This is found in both animal studies and in human studies.”

Pre-print says that those with type A blood are more likely to test positive in a hospital (implying hospitalization?) than B or AB, who are in turn more likely than those with type O. All differences were statistically signficant but modest
