From the Document: "The UK Government has declared the spread of the novel coronavirus (2019-nCoV) to be a serious and imminent threat to public health. [...] This step gives government authorities additional legal powers to control the disease, such as restricting people's movement. The Department of Health and Social Care has said that people infected with novel coronavirus could now be forcibly quarantined and not allowed to leave, and could be forcibly sent into isolation if they posed a threat to public health."
