      Broad surveillance could be achieved by using less precise but faster and cheaper antibody blood tests. While, clinical, RNA-based, diagnostic tests could be used on the frontlines to confirm likely cases. 9/

      Antibody blood tests look for antibodies developed to fight the virus in the blood of the infected & can tell if a person has been infected even after they have recovered because the body retains antibodies against pathogens it has already overcome. https://www.sciencemag.org/news/2020/03/new-blood-tests-antibodies-could-show-true-scale-coronavirus-pandemic … 10/

      Current clinical testing is biased toward the sick & ill. So we don't know how much COVID-19 there is or how dangerous it is. This uncertainty => over and/or under reaction. 11/

      Broader surveillance testing should use (stratified) random sampling & active learning to help us learn where the virus is quickly. https://www.statnews.com/2020/03/17/a-fiasco-in-the-making-as-the-coronavirus-pandemic-takes-hold-we-are-making-decisions-without-reliable-data/ … 12/

      While a large scale stratified random sample may be costly & impractical, in Holland they are taking 10,000 samples from all blood donations in the past week (shared by @PeterLugtig) https://nos.nl/artikel/2327585-bloedbanken-gaan-opbouw-immuniteit-coronavirus-onderzoeken.html … 14/

      You could also imagine beginning with a few small representative cities across the US, as several people including @cdsamii have suggested. 15/

      But the current approach, no matter how large, will always provide biased estimates of prevalence & morbidity/mortality because, as @deaneckles pointed out, computing standard confidence intervals from big, biased data does not yield valid inference. https://statistics.fas.harvard.edu/files/statistics-2/files/statistical_paradises_and_paradoxes.pdf … 16/

      Also... There are some reports that CA has been doing random testing and that this surveillance informed their policy:https://twitter.com/yashar/status/1241525616219787264?s=19 …

      4. Governor Newsom says the State of California has done random testing around the state, of people who weren't even complaining of symptoms, to see how coronavirus may have spread and that it's informed the state's decision making.

      CA is using testing as "community surveillance"... "broad random tests of otherwise young, healthy people, which allowed health officials to improve their use of scarce medical resources." https://m.arcamax.com/currentnews/newsheadlines/s-2341501 …pic.twitter.com/KbQWjzEJbO

      Want "better data"--well perhaps we should take those non-existent tests and do a random sample of the entire US for a few weeks and then decide to act? As @mlipsitch an actual real infectious disease epidemiologist has said we have more than enough information to act now. 6/

          I appreciate the sentiment and, frankly, agree, but fear we're right back where we left it... To reiterate: not arguing we take our limited tests and "do a random sample of the United States." Instead asking if smart sampling of marginal cases or w/ antibody tests makes sense.

          Is there a fast antibody test yet? Last I heard it was in the works but some time away
