A Twitter thread by Naval.
Very educational talk on coronaviruses from a Johns Hopkins scholar, @AmeshAA. h/t @TokTeacher

(For the record, I’m more concerned than Brett at the moment)
[8:33] Coronaviruses are everywhere and peak in the winter / spring every year
[8:48] All of you have had a coronavirus in your life...just not this coronavirus. And you get reinfected with them, because antibodies fall over time.
[15:10] When a US Senator shames drug companies into stopping Zika vaccine development.
[25:20] We are in a mild-moderate pandemic (in life-years potentially lost).
[26:24] This will become endemic and return in the fall.
[27:50] This is not containable. Don’t quarantine or panic. Become personally resilient. Make the healthcare system resilient.
[33:00] Containment will inevitably fail and doesn’t buy much time.
[34:00] Wearing an N95 mask can’t be sustained for long. Wear only if sick.
[35:20] More likely undiagnosed cases than fatalities. 1%-2% fatality rate too high. Discrepancy between Wuhan and non-Wuhan cases. Health care interventions and ICU quality matter.
[37:00] Incubation average is 6 days, but up to 14 possible.
[38:30] mRNA vaccines like the Moderna vaccines can go into trials very quickly. Many, many vaccine candidates.
[40:00] Coronaviruses tend to be stable against mutation (for RNA viruses). There’s no selection pressure to mutate right now and this is spreading easily.
[41:00] Many cases are clinically indistinguishable from the common cold or the flu. It’s not really containable in any country, that’s a temporary illusion.
[43:25] In temperate zones, coronaviruses display seasonality. In tropical areas, no seasonality for respiratory viruses.
[44:00] Vaccine is at least 12-18 months away...if we get one. Coronavirus vaccines didn’t get full effort in the past because they were either too mild and varied (colds) or too short-lived (SARS).
