Omicron: Two weeks on

The World Health Organisation says the Omicron strain of coronavirus has now spread to 57 countries since it was first reported two weeks ago. We bring together doctors in South Africa who treat Covid patients to discuss what they have learnt so far about Omicron.

We also answer your questions about Covid-19 with the help of Dr Pedro Hallal, an epidemiologist at the University of California in San Diego.

And the British Prime Minister Boris Johnson is under pressure to clarify whether a Christmas party took place at this official residence a year ago, in breach of Covid lockdown rules. We talk about the fallout he faces with our political correspondent and hear reaction from the British public.
