      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 …

      Replying to @zeynep
      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 …

      The preliminary results have an interesting phrase: About 2.5% of the participants that didn't report symptoms had antibodies. ~~ "Finalmente, un 2,5%de los participantes que no refieren ningún síntoma presentaron anticuerpos IgG."

      Indeed, though that is a lower number than I had seen people hope for.

          2.5% asymptomatic might be mostly false positives in the antibody test, too.
