Nearly 1,400 people have died in the Democratic Republic of Congo.

Dr Jeremy Farrar, the director of the Wellcome Trust, said the epidemic was the worst since that of 2013-16 and has showed “no sign of stopping”.

Two people have also died in neighbouring Uganda, the first cases of Ebola reported in the country.

A five-year-old boy infected with the virus died on Tuesday and his 50-year-old grandmother died on Wednesday, the Ugandan health ministry said.
