"Using data through April 20, 2020, we fit a statistical model to COVID-19 case fatality rates over time at the US county level to estimate the COVID-19 IFR among symptomatic cases (IFR-S) as time goes to infinity. The IFR-S in the US was estimated to be 1.3% (95% central credible interval: 0.6% to 2.1%). County-specific rates varied from 0.5% to 3.6%."

- gpm 7y agoHave you read that study? It's over-extrapolating from shit data with a overly fancy mathematical model. I don't fault the authors for trying, it is an interesting attempt, but I weight their results substantially less heavily when forming my world view. Not to mention which, some estimates of asymptomatic case rate go up to 50% (others substantially less so, it probably depends both on age range and what you define as asymptomatic) By the way, direct link to the study is https://www.healthaffairs.org/doi/full/10.1377/hlthaff.2020.00455?utm_campaign=covid19fasttrack&utm_medium=press&utm_content=basu&utm_source=mediaadvisory https://www.healthaffairs.org/doi/full/10.1377/hlthaff.2020....
- titzer 7y agoRemember 2 months ago when data from China indicated the CFR was 1-2%? And then it exploded in Italy and now we see CFRs in the 5-15% range worldwide? Yeah. I am really sick of flippant underestimates of the seriousness of this motherfucking disease. Deaths are still being underreported and no one has shown a statistically sound study of what the real infection rate is, even as it continues to climb, so both the numerator and denominator of this fickle IFR quantity have got massive errors on them.
