Britain on Wednesday warned all of its citizens against travel to China’s Wuhan city due to the novel coronavirus pandemic.

“In light of the latest medical information, including reports of some person-to-person transmission, and the Chinese authorities’ own advice, we are now advising against all but essential travel to Wuhan,” British Foreign and Commonwealth Office said in a statement.

The statement said “the safety and security of British nationals is always our primary concern, and we advise British nationals travelling to China to remain vigilant and check our travel advice.”
