It is better to avoid places that are close to the center of the outbreak. Though, travelling to the center of outbreak can be even impossible because of quarantine in such areas and restrictions put by other countries. The State Department has issued its highest-level travel alerts for China, advising Americans to avoid traveling there for now, Russia has closed its Eastern borders. Many other countries have decided to limit their "travel exchange" with China as well. Even large companies, including Facebook, have stopped sending their workers to business trips to Hubei or near-located provinces.
Visiting other countries is safe. Since 99 percent of the cases have been confirmed in China, mostly in Wuhan, "the risk of acquiring this infection outside of Hubei and, truly, outside of China is remarkably low," says Isaac Bogoch, an epidemiologist at the University of Toronto.
At the same time, there is another "complication" of travelling not connected with being infected or visiting China. There are news of "quarantined" vessels. For example, Japan has quarantined a cruise ship after some people said they felt ill (they were checked for the virus later and are negative, but all the other passengers now have to be checked as well, so they are still on the ship). Another, British, vessel was quarantined last week.
