@michaelmina_lab @DonEford @YouAreLobbyLud @DailyJLee They work less well for creating a "safe" gathering of N people. It is far more likely that the gathering contains someone contagious and is not in fact safe when N is higher and ALSO when prevalence is higher.
@michaelmina_lab@DonEford@YouAreLobbyLud@DailyJLee他们在创建N人“安全”聚会方面做得不太好。更可能的情况是，聚会中有传染性的人，而且在N较高以及流行率较高时，实际上并不安全。
