@StopCoronaVir12 @BruceSt22513754 @BallouxFrancois @kallmemeg Infection was not an endpoint. The endpoint was symptomatic disease i.e. getting sick with covid. Only people who got sick were tested. You can't determine infection from that because you don't know who got infected by didn't have symptoms. It wasn't part of the study at all.
@StopCoronaVir12 @BruceSt22513754 @BallouxFrancois @kallmemeg 感染不是终点。终点是症状性疾病，即感染新冠病毒。只有生病的人才能接受检测。您无法从中确定感染，因为您不知道谁感染了没有症状。这根本不是研究的一部分。
