COVID-19: Will ending 'zero-COVID' overwhelm China's health service?

There are fears in China that the easing of its severe COVID-19 restrictions may lead to a surge in infections that could overwhelm the country's health services.

People with the virus can now isolate at home if they have mild symptoms, and everyone can travel more freely inside the country.

But infections are running at 30,000 a day and that is likely to jump now the restrictions are ending.
