@michaelmina_lab @CDCDirector The positivity rate if you back it out (they don't report it explicitly as far as I can tell) is sky high. It is clear that only the most obvious cases are being tested, likely at an advanced stage.
@michaelmina_lab @CDCDirector 如果您退出（据我所知他们没有明确报告），阳性率会很高。很明显，只有最明显的案例正在测试中，可能处于后期阶段。
