      Today both France and Spain (two badly hit countries) have come out with seroprevalence numbers. (France is a model, paper linked below. Spain was representative sample/survey of 60K; I don't have the paper yet). Both are ~5 percent. If that holds up, that is very very bad news.https://twitter.com/hsalje/status/1260606369805320195 …

      Despite 20,000+ COVID19 deaths, we find only ~5% of France infected. The lockdown, eased on Monday, reduced transmission by 80%, however R still close to 1 (~0.7) with 3-6k daily infections, leaving little room for post-lockdown increases @ScienceMagazine https://bit.ly/2zzLKJX  pic.twitter.com/IaeVeHYiDn

      One hopeful scenario had been there is a lot of asymptomatic transmission we are not noticing. Maybe. But if some of the worst hit countries are still composed of almost completely immunologically naive populations, that's a different challenge. Quite confusing, to be honest.

      Clarification re: my Sweden seroprevalence question. Lancet article said 25 percent for Stockholm. The question re:Spain and France only at 5 percent remains, though. If that's the real seroprevalence, big death toll despite (relatively) limited spread.https://twitter.com/oli_bou/status/1260644675083358208 …

      Unless I'm mistaken, Sweden claimed 20-25% in Stockholm, not in the country at large.

      Even the worst hit Spanish regions appear to be at ~10-14% seroprevalence. Hopefully we'll have more distribution/network data—but one guess would be the spread in nursing homes/vulnerable populations couldn't be checked even as everyone else locked down.https://twitter.com/datadista/status/1260620767240302593 …

      This modelling study from Sweden suggests 26% of Stockholm county will have been infected by May 1st (https://www.folkhalsomyndigheten.se/contentassets/2da059f90b90458d8454a04955d1697f/skattning-peakdag-antal-infekterade-covid-19-utbrottet-stockholms-lan-februari-april-2020.pdf …). However, our estimates of under-reporting suggest only 5-10% have been infected so far (https://cmmid.github.io/topics/covid19/global_cfr_estimates.html …). So what's going on? 1/

      New Indiana data. Random sample. Prevalence: 2.8% These findings contradict the hope that many had mild/asymptomatic infections and are now immune. This suggests places that were spared (so far) did not have big outbreaks.https://twitter.com/aaronecarroll/status/1260668185998700547 …

      Now to results! How many are currently infected? 1.7% How many more have antibodies? 1.1% Total prevalence in Indiana? 2.8% Anyone hoping that great numbers of Americans have been infected, but with no symptoms or very mild illness is going to be disappointed.

          Early to mid-April but still. Stockholm is the highest infected region. So there is enough asymptomatic/presymptomatic transmission to create a challenge for containment, but not to the degree that some people had been hoping for. (Would’ve been nicer. But reality is reality).https://twitter.com/AdamJKucharski/status/1263172093149155329 …

          There's definitely a lot of motivated reasoning going on in the way people approach the "asymptomatic prevalence" question. Some people are using it as a way to psych themselves up to reckless acts of indifference.https://twitter.com/ragepath/status/1241604709170819073 …

          There's some kind of magical thinking about this "many people who have it are asymptomatic" argument. I think people are trying to convince themselves they *have* it, but are also immune to it.

          Which test did they use because 1.1% is within the false positive rate of the antibody tests depending on the test they used. The one they used in Santa Clara can show up to 3% false positives.

          2.8% is a lot, around 190,000 people. Currently the positive cases are around 25,000. Which means many more do not need any medical attention (=mild or asymptomatic).

          Do you know what counts as "seropositive", existence of any antibodies vs some level? Also is there anything on whats the spectrum of level of antibodies of the confirmed cases on mild vs hospitalized? Even first time most are safe from the dangerous version but is that just luck
