Africa’s top public health agency says the Democratic Republic of Congo (DRC) and other countries on the continent could start vaccinating against mpox within days.The DRC is the epicentre of a more deadly strain of the virus that emerged last year and has subsequently spread to some 12 other African states, with confirmed cases in at least 3 countries outside the continent.Last week, the World Health Organization declared the spread of the new strain a public health emergency of international concern.
