Good morning, you have reconsidered that the incubation period of the virus can be longer than 14 days, have you observed much variability in this? I had read it but also read that it is being questioned, I would like to know the opinion of the colleagues from China. Thank you. / 你好，有人认为这个病毒的潜 伏期有可能超过14天，是否有检测到很多的异常潜伏期病例?我有读到过，但同时大家也有质疑声，我希望能听到中国 的医护同事的意见，谢谢。
