What's the 'official' travel advice?
“There is an ongoing outbreak of coronavirus,” say the Foreign and Commonwealth Office (FCO). “The virus originated in Wuhan City, Hubei Province but cases have been confirmed in other parts of China and in some countries, including the United States.
“You should comply with any additional screening measures put in place by the local authorities. Given the fast changing situation, you should check the latest entry requirements for your destination and keep in touch with your airline, cruise line or tour operator before you travel.
“With effect from 2 February, the US Government will not permit entry to the USA of any foreign nationals who have visited China 14 days or less prior to their travel to the USA.
“More information for travellers to the USA can be found on the US Centre for Disease Control (CDC) website, including information about cases in the United States.
“Further advice is available from Public Health England, and the TravelHealthPro website.”
