Two cases of coronavirus are now confirmed in the UK, Chief Medical Officer Chris Whitty said in a statement on Friday.
"We can confirm that two patients in England, who are members of the same family, have tested positive for coronavirus," the statement said.
"The patients are receiving specialist NHS care, and we are using tried and tested infection control procedures to prevent further spread of the virus."
Authorities are now working to identify any contacts the patients had, to prevent further spread, Whitty said.
"We have been preparing for UK cases of novel coronavirus and we have robust infection control measures in place to respond immediately."
