Hong Kong’s hospital system could face “collapse” as it grapples with a sharp rise in coronavirus cases, the city’s leader Carrie Lam has warned.

She said the city was “on the verge of a large-scale community outbreak” and urged people to stay indoors.

New regulations, including mandatory face masks and the closure of dine-in restaurants, kicked in on Wednesday.

Hong Kong – which had early success against Covid-19 – is now regularly reporting over 100 new daily cases.

Less than a month ago, the average number of new daily cases was under 10.
