Actually, yeah, it can. Unlike a typical coronavirus, this one leaves its victim infectious PRIOR to showing symptoms.
That’s a very serious problem. As with the tour bus driver in Japan who was infected; none of the tourists were showing signs when he came into contact with them.
Now think of all the people he came into contact with prior to showing symptoms, or how many people the original infected tourist(s) came into contact with.
To me, it’s a miracle that Japan didn’t explode with cases from just this incident alone.
The silver lining, so far, is that while the virus is passed by close contact, it seems to have a low infection rate.
