Xi Yanchun:
Thank you very much, Professor Li. And great thanks to all of the experts. Thank you for what you have done for the patients here, and also what you have done for the people.
So now the floor is open for questions. May I remind you to please identify yourself before raising questions. Also, please speak clearly and slowly, because we are a thousand kilometers away. Okay, please raise your hands.
Xi Yanchun:
Okay, the gentleman in the first line in blue shirt.

Thank you. This is a question from Reuters. Actually, two questions. First, how many cases are there of people in Hubei who recovered and then were later were diagnosed with the virus again? Is there a chance that this will keep recurring? And my second question: last month, a 70-year-old man in Shennongjia was tested positive for the virus. He visited his sister in January, but did not show any symptoms until 27 days later. How should we deal with such cases that have long incubation periods? How many of such people are there? Thank you.
Du Bin:
Thank you, sir. Thank you for your questions. I’ll answer the second question first. Regarding the patient in Shennongjia, I actually have no idea as to how this patient behaved and the details of the case. But I will address the long incubation period, which hasn’t been reported nor discovered, either here in Wuhan, Hubei, other provinces or other countries. According to most publications, right now we understand that the median incubation period is five to seven days. The longest incubation period is 14 days, and there’s no data showing that an even longer incubation period has ever existed.
And for your first question, the answer is yes. There have been several cases reported about people who have tested positive for the novel coronavirus RNA after being discharged or after multiple negative results. We know that there are such cases in Hubei and Wuhan as well. But we have no idea how many of them are there. More importantly, according to current research results, there’s no evidence that these patients, after being tested positive again for the coronavirus RNA, have the ability to transmit the virus to other people or to their close contacts. There’s no evidence.
Xi Yanchun:
Thank you. Ok, next question. Please. The gentleman in the middle area in black suit, second row in the middle area.
