GENEVA: A yellow fever outbreak in Angola and Congo has been brought under control by a major vaccination campaign, the head of pandemic and epidemic diseases at the World Health Organisation said on Tuesday. Sylvie Briand told a UN briefing in Geneva that the level of vaccinations in Angola, as well as in Kinshasa and border regions, meant that there was no risk of a major outbreak there, although there were still 32 endemic countries in Africa, so further outbreaks could not be ruled out.
