Yellow fever outbreak Angola, Democratic Republic of the Congo and Uganda 2016-2017

Yellow fever outbreak ends

14 February 2017 – The Democratic Republic of Congo declared the end of the yellow fever outbreak following a similar announcement in Angola on 23 December 2016, bringing an end to the outbreak in both countries after no new confirmed cases were reported from both countries for the past 6 months.


Winning the war against yellow fever

25 November 2016 -- Four months have passed without a single case of yellow fever related to the outbreak in Angola and the Democratic Republic of the Congo, thanks to the joint response activities of national health authorities, local health workers, WHO and partners.

Types of transmission of yellow fever

7 October 2016 -- Yellow fever is transmitted by the bite of infected mosquitoes belonging to the Aedes and Haemogogus species. The movement of infected people spreads yellow fever between different places. This graphic shows the three different types of transmission cycle – sylvatic (also known as jungle), intermediate and urban yellow fever.

Resetting the yellow fever strategy

16 September 2016 -- Changes in the way humans live and work, and the resurgence of mosquito vectors, particularly Aedes aegypti, have raised the global risk of yellow fever.

A coalition of partners working to stop yellow fever outbreaks met in Geneva on 12 September 2016 to develop a new strategy - Eliminating Yellow fever Epidemics (EYE). This strategy aims to protect the populations most at risk, ensure a ready supply of yellow fever vaccine, build resilience in urban centres and prevent international spread.

Emergency Committee meeting on yellow fever

31 August 2016 -- The Emergency Committee under the International Health Regulations concerning yellow fever met today. It decided that the yellow fever outbreak in Angola and DRC does not constitute a Public Health Emergency of International Concern (PHEIC). Despite considerable progress, the outbreak remains a serious public health event that warrants continued action and international support.

Logistics pathway to protect 10.5 million people from yellow fever

26 August 2016 -- The logistics to vaccinate more than 10.5 million people in 32 health zones in Kinshasa provinces and 15 health zones in remote areas bordering Angola, has been a complex and challenging logistical undertaking. WHO has deployed 15 logisticians to plan and transport more than 10 million syringes, vaccine doses in more than 38 000 vaccine carriers by truck, car, motorcycle, by boat and often by foot to the targeted 8000 vaccination sites, many of them in remote and hard to reach areas.
