  1. @Austin O'Brien I believe there are two types, 1) PCR, and 2) antibody. I don't think there is an "antigen" test per se. . PCR tests can find virus RNA, a sign of current infection. Antibody tests can find antibodies from current and past infections. . Antigens are any foreign particles that the body recognizes as a problem and makes antibodies to fight. The body doesn't recognize the RNA sequence, so it is (probably) not an antigen. Thus, PCR (which looks for RNA sequences) is not an antigen test. . Not a specialist here, just a BA biology guy.

  2.  @CricketsBay  Correct. There are actually three test types: PCR and Antigen = virus now Antibody = after virus https://www.npr.org/sections/health-shots/2020/05/01/847368012/how-reliable-are-covid-19-tests-depends-which-one-you-mean

  6.  Don P  An IFR of 0.1% is believable, if a nation has missed 90% of its cases but done a good job counting deaths, and estimated a 1% rate with the flawed data. .

  7. Could be. However there probably is also some cross-resistance with cold viruses. https://www.nature.com/articles/s41586-020-2550-z

  9.  @Justlookin958  Halfway is a bombshell of a milestone lol. . Thailand has had about 15-20m infections. It's about 1/3rd of the way. . UK about 4-6m. About 1/7h to 1/10th of the way. . US has had no random surveys, so we have no clue.

  10. Did they do a randomized survey? If not, then no population estimates are reliable.

  11. minus overlap very important point however
