Scientists at the World Health Organization say nearly a quarter of a billion people in Africa could catch coronavirus in a year.

Their study, published in BMJ Global Health, says between 150,000 and and 190,000 Africans could die from Covid-19.

It says 5.5 million people would need hospital treatment, overwhelming services already struggling to treat malaria, tuberculosis and HIV.

Coronavirus has been relatively slow to spread in Africa but has already taken hold in camps for displaced people in South Sudan.
