Be proactive and protect yourself from yellow fever
People living in or travelling to potentially endemic areas of yellow fever transmission should protect themselves. The yellow fever vaccine provides life-long protection against the disease. You should protect yourself from mosquito bites by wearing light-coloured, long-sleeved shirts and trousers, sleeping under a bed net day and night, using insect repellents and getting rid of stagnant water from places where mosquitoes breed.
Information products on yellow fever and vaccination are available in multiple languages including Portuguese.
25 November 2016 -- Four months have passed without a single case of yellow fever related to the outbreak in Angola and Democratic Republic of the Congo, thanks to the joint response activities of national health authorities, local health workers, WHO and partners.
Changes in the way humans live and work, and the resurgence of mosquito vectors, particularly the Aedes aegypti mosquito (which spreads Zika, dengue fever and chikungunya), have raised the global risk of yellow fever. Two large yellow fever outbreaks in Angola and Democratic Republic of the Congo are now under control but these are just warnings of bigger outbreaks to come if action is not taken.
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.
The outbreaks of yellow fever in Angola, Democratic Republic of the Congo and Uganda have placed great demand on the global supply of yellow fever vaccines. The global stockpile of 6 million vaccines for emergency response (normally enough for a year) has already been replenished twice this year.
This timeline shows the demands on the global vaccine supply since early 2016.
The ongoing yellow fever outbreak in Angola is mostly in urban areas but at risk of spreading to other provinces and across borders to neighbouring countries. Extensive local transmission in the capital city Luanda, has prompted multiple vaccination campaigns in Angola as well as in Democratic Republic of the Congo and Uganda.
Read WHO’s latest guidance on communication and social mobilization methods to conduct yellow fever vaccination campaigns. The guidance also provides information on the monitoring and evaluation of communication and social mobilization techniques. These 10 points from field experience are especially useful for district-level planning. The document is available in English, French and Portuguese. A Spanish version is also in a pipeline.
