Q. What lessons or warnings do you think this pneumonia epidemic has brought to the public? As a scientist, do you have any research plans for the virus?

A: We’ve seen several outbreaks of the coronavirus, as well as others such as H1N1 influenza, Ebola, and the Zika virus. A fast response to prevent spread is needed until science can give us the tools to deal with the virus. Aside from analyzing publicly available sequence data, I have no plans to work with these viruses.

Q. Coronavirus outbreaks are currently occurring worldwide, including in the United States. Are you worried about your family in the United States? Where are they and how are they fighting the epidemic? What are the differences between China and the United States in fighting the epidemic?

A: I am very disappointed with the slow response in the United States. They had a chance to be proactive and missed that opportunity. Some areas have started to take action, but many in the population are not supporting the efforts. In a situation like this, everybody has to do his or her part. I am more concerned for my friends and family in the United States than I was for my family here in China.

Q: Is there anything else you would like to share about this outbreak?

A: I was impressed by the rapid response in building hospitals and mobilizing medical professionals to fight the epidemic. I am grateful for the actions of the health care community and volunteers. There are some real heroes out there.

Q. Do you want to live in Suzhou all the time?

A: It’s a beautiful city and I feel that the work that I’m doing here is important. I do miss the California beaches, so maybe I’ll take a trip to Hainan Island once things return to normal.
