About 58 million people in China have been forced into lockdown as residents in the heart of the coronavirus outbreak are told only one family member can leave the house once every three days.
The central Chinese province of Hubei, the epicentre of the outbreak, has seen residents ordered to stay home until further notice.
Under new rules, which came into effect on Sunday, each one of the province's 200,000 rural communities will be sealed shut, with only one guarded entrance. Similar restrictions will be placed on urban residential compounds.
Only community residents and vehicles are permitted to enter, and only one person from each household may leave every three days to buy essentials from the supermarket.
"In principle, every villager should stay at home. If he really needs to step outside, he has to wear a mask and keep a minimum 1.5 metres from other people," the regulations say, according to the South China Morning Post.
