Health officials have contacted hundreds of conference attendees in London, after it emerged one of them was later diagnosed with coronavirus.
The person, who has not been identified, was at the UK Bus Summit at the QEII Conference Centre last week.
Two Labour MPs who were also at the conference said they were well but cancelling public engagements until 20 February as a precaution.
So far, nine people in the UK have tested positive for the virus.
