@michaelmina_lab @alexmeshkin Good questions.
What the hypothetical "I" wants to know is, if I have dinner parties where everyone is taking a test, say weekly, how likely am "I" going to get sick (or infected and become part of a chain)? I don't really care about "PCR" in practice, that's just another test.
@michaelmina_lab @alexmeshkin 好问题。
假设的“我”想知道的是，如果我举办晚宴，每个人都参加测试，比如每周一次，那么“我”生病（或被感染并成为连锁店的一部分）的可能性有多大？在实践中我并不真正关心“PCR”，那只是另一个测试。
