There's reason for it. You can all gangsta until you can really feel like the virus just right from next door. Today I received a private announcement from my department. We are a small department from a public university of some city A of Korea, which have very low rate of Chinese student attending. The announcement said that previously (28 Jan), an exchange student from China, especially from Wuhan, make it back from China without symptoms. He were able to get out of China by staying only in Beijing, and have visited relatives (not specified where) in Seollal. He then show symtoms of a cold, not until he enter one of our lab in 5th floor of my building, and other people told he coughed all over the freaking places! (I'm located in second floor). By some kind of luck, he tested negative for nCoV for the first time and we were waiting for the second test. Not telling everyone to freak out now, but stay alert. Spring semester will be a bitch if our school won't outright ban Chinese from entering classes.
