With concerted response, Angola and the Democratic Republic of the Congo (DRC) have successfully controlled one of the world’s largest and most challenging outbreaks of yellow fever, the United Nations health agency announced. “We are able to declare the end of one of the largest and most challenging yellow fever outbreaks in recent years through the strong and coordinated response by national authorities, local health workers and partners,” said Matshidiso Moeti, the World Health Organization (WHO) Regional Director for Africa, commending the unprecedented and immense response. Since it was first detected in Angola in December 2015, the outbreak claimed at least 965 lives in the two countries, with thousands more suspected. WHO said more than 41,000 volunteers and 8,000 vaccination teams with more than 56 non-governmental organizations undertook emergency inoculation campaigns, immunizing more than 30 million people. In the first six months of 2016 alone, the partners delivered more than 19 million doses of the vaccine – three times the six million doses usually put aside for an outbreak.
