There's a lot of Chinese student in my town and many of them have been back for ChineseNew Year. Most of them live in new build blocks which are basically just cubicles with shared washing, sanitation and cooking facilities. I'm quite concerned for the students but not really myself yet.
Having said that, they are kind of used to this sort of thing because of previous scares in China so they're scrupulously clean and know about infection control.
I hope they all stay healthy, they're nice kids and it's good to have them here.
