“We estimated the epidemic growth rate by analyzing data on the cases with illness onset between December 10 and January 4, because we expected the proportion of infections identified would increase soon after the formal announcement of the outbreak in Wuhan on December 31.”

正文Method部分的statistical analysis小节的第二自然段：
“We estimated the epidemic growth rate by analyzing data on the cases with illness onset between December 10 and January 4, because we expected the proportion of infections identified would increase soon after the formal announcement of the outbreak in Wuhan on December 31.”
请问这个“formal announcement”是指的哪个发布会？
但是，后来出现了各种：未发现人传人，有限人传人，人传人等争议性判断
然后现在统一甩锅给科研人员
只能回答上一个问题，甩锅不甩锅这个问题不清楚。
这个疫情不是完全没通报的，而是说早期通报的传染性跟现在表现出来的不一样，许多人的嘈点在这里。因为如果只是动物传人，很多人不担心。
各个方面，科研人员，医院，防疫和领导，到底什么时候知道人传人，可能是这个“甩锅”问题的重点。大家各执一词。
人人知道应该两个“亲自”的草包背锅，人人都不敢说出来
