总统很可能与其它一些人都是9-26感染的。他很可能星期三的测试是阳性，但没引起重视，星期四其助手发病，他再测，也是阳性。这次才引起重视。下面USA Today引述川普医生的话，星期四"when we repeated testing"，请注意"repeated"，显然早些时候已经测试了，只是当时没有症状，没有肯定而已。在周六上午，医生说的72小时into the diagnosis，应该不是口误，这时候知道星期三测的阳性结果是真实的，应从那时算起。当时御医没有意识到说真话的后果，也不能当着那么多知情的医生面前说谎。
"Thursday afternoon, following the news of a close contact is when we repeated testing, and given kind of clinical indications I had a little bit more concern, and that’s when – late that night – we got the PCR confirmation that he was," Conley said, referring to a molecular diagnostic test.
How soon after I'm infected with the new coronavirus will I start to be contagious? The time from exposure to symptom onset (known as the incubation period) is thought to be three to 14 days, though symptoms typically appear within four or five days after exposure. We know that a person with COVID-19 may be contagious 48 to 72 hours before starting to experience symptoms. Emerging research suggests that people may actually be most likely to spread the virus to others during the 48 hours before they start to experience symptoms. If true, this strengthens the case for face masks, physical distancing, and contact tracing, all of which can help reduce the risk that someone who is infected but not yet experiencing symptoms may unknowingly infect others.
他每天都检测一次，星期四才测出阳性。如果是1上星期六感染的，需要五天才能测出来？

星期四的报告也许是星期三或更早的检测？
因为要送样品到指定的实验室，加上做试验，应该需要几个小时。一般人则需要一两天或更长时间。
我很怀疑医生说的72小时是真实的，即星期三检查的结果为阳性，星期四再次阳性，而且周四总统已经有症状，也知道助手中招了。这时总统才公开消息。
倒是可能周三的结果是阴性，医生怀疑是假阴，周四再测得到了确认。
认为天佑总统，总统是特殊材料制成的。
72 小时诊断
48小时打抗体
都错了的可能性太小。
有提高的空间。
