3/ Here's some more data- why did life expectancy plummet in 1917-1918 (by 10 years!) then rebound completely?
Life expectancy is the average number of years a group of infants would live if they were to experience prevailing age-specific death rates throughout their life
1/ The Denmark variant story was pointed out by several people as being quite concerning- this line struck me - "Cases involving the variant are increasing 70 percent a week in Denmark, despite a strict lockdown"
But the actual data was hard to pin down- so I dug it up
2/ "The U.K. variant was 2 percent of sequenced coronavirus cases the last full week of 2020. By the second week of January, it had risen to 7 percent."
But in the context of declining cases what does that mean?
3/ But those aren't actually the true cases, cause despite the headline "Denmark is sequencing all coronavirus samples..." while they are *trying* to sequence all, the number of cases with a genome of sufficient quality relative to the total number of cases ranges w-w from 10-36%
2/ What's the natural response then, from those all the way down the distribution chain, from state administrators to hospital execs worried about "wrong people" getting vaccinated first?
You spend more time collecting data, parsing into finer and finer gradations
You slow down
3/ Hospitals and nursing homes don't release more to staff until every i has been dotted.
States don't release more to hospitals and nursing homes until they've used up allotment
feds don't release more to states
Amidst a vaccine shortage, available supply sits in warehouses.
1/ Opening schools in the midst of a COVID surge is a hard problem with unavoidable tradeoffs.
There are absolutist statements on either side of the debate, so I expect passionate rebuttals, but let me lay out a decision-making framework, from an epidemiologists' perspective
2/ First off, we have to make sure that the schools have the resources and space to implement the 5 key mitigation
strategies correctly and consistently.
Not a given.
*Masks
*Social distancing
*Contact tracing
*Hand hygiene
*Cleaning and disinfection
first 2 >> last 2
3/ Let's say we have some resources for testing, how does that contribute?
What we are trying to achieve?
Do you think the goal is Screening (identify asymptomatic infectious cases before they can expose others) or Surveillance (understand incidence to inform policy)?
