You should do it sooner than later if you have decided to go anyway. The numbers are not looking good: http://www.nhc.gov.cn/xcs/yqtb/list_gzbd.shtml. It's like 200 200 200 200, then 500 500 500 500, then 2000 yesterday.
But they're mostly in Jilin, so use your own judgement.
It may be too late. My family members decided to leave 3 weeks ago, and just arrived at O’Hare last night. International flights are very limited, but they generally do not go where you need them to go. So you have an additional layer of finding connections to where you need to go. You may have to wait weeks for available seats on the multiple airplanes you will have to use.
One thing that I didn’t realize is that getting back into China/HK is not easy either. My brother will spend 2 weeks here in the US getting his wife and kids set up and then go back to work. But before he can get back in and spend 3 weeks in quarantine, he will have to go spend 2 weeks in Germany to “decontaminate” himself from spending time in the US!!!
