Coronaviruses will not survive in the environment for the several weeks it will take parts to travel from China. You are much more likely to catch it in places frequented by Chinese tourists, like central London or Oxford.
There is speculation that one of the two confirmed UK cases was a Chinese tourist at
Bicester Village.
There is no reason to panic about this anyway. Both the infection and mortality rates seem to be comparable with conventional influenza - people in otherwise good health aren't going to suddenly drop dead if they catch it. It's not like Ebola.
