Health officials are trying to discover how a man in England caught coronavirus, after he became the first person to infected within the UK.
The man, from Surrey, had not been abroad recently – unlike the 19 others who have tested positive in the UK.
Health minister Helen Whately told BBC Newsnight officials are trying to trace people he was in contact with.
Meanwhile, the government is expected to publish emergency legislation next week, if the virus spreads.
The package of measures would be designed to help the public sector – such as the NHS and schools – cope with the outbreak, if there was a serious rise in cases.
There are few details about what the measures could involve – but school class sizes in England is one area which would be addressed. They would be permitted to rise above statutory limits, in the event of widespread teacher absences.
Prime Minister Boris Johnson, who said the virus outbreak was now the government’s top priority, will chair a meeting of the government’s Cobra emergency committee on Monday.
He had faced criticism from Labour, who said he needed to “get a grip” on the situation and questioned why he was waiting until next week to hold the meeting.
