China has widened a lockdown in Hubei province - the centre of the coronavirus outbreak - as the death toll climbed to 26.
The travel restrictions will affect at least 20 million people across 10 cities, including the capital Wuhan, where the virus emerged.
On Thursday, a coronavirus patient died in nearby Hebei province - making it the first death outside Hubei.
Another death was later confirmed in north-east Heilongjiang province.
The north-eastern area borders Russia and is more than 2,000 kilometres (1,200 miles) from Wuhan.
Nationally, there are currently 830 confirmed cases of patients infected with the virus.
The lockdown comes on the eve of Lunar New Year - one of the most important dates in the Chinese calendar, when millions of people travel home.
In Shanghai, the Disney Resort said it was "temporarily closing in response to the prevention and control of the disease outbreak".
