16 January 2018 - Since December 2016, Brazil is experiencing an upsurge of yellow fever virus activity. Considering the increased level of yellow fever virus activity observed across the state of São Paulo, the WHO Secretariat has determined that, in addition to the areas listed in previous updates, the entire state of São Paulo should also be considered at risk for yellow fever transmission. Consequently, vaccination against yellow fever is recommended for international travellers visiting any area in the state of São Paulo.
21 December 2017 - Reports of yellow fever cases throughout Nigeria are escalating concerns about the risk of large, costly, and difficult-to-control outbreaks in urban areas requiring huge supplies of life-saving vaccines and increasing the potential for large-scale national and worldwide spread. Fears that the situation in globally connected Nigeria could soon mirror the massive 2016 outbreak in Angola, during which cases were exported to neighboring DRC and as far as China, are raising urgent calls for quick containment.
1 December 2017 - The International Coordinating Group (ICG) on vaccine provision for yellow fever has provided 1.4 million vaccine doses for an immunization campaign that started on Saturday, 2 December 2017 to help control an ongoing yellow fever outbreak in Nigeria.
The EYE Strategy addresses three important global health agendas
EYE is a global and comprehensive long-term strategy that aims at ending yellow fever epidemics by 2026. Areas of work encompass management of global vaccine supply including an emergency stockpile, and country implementation and engagement for improving surveillance and outbreak control.
The EYE strategy is committed to the main global health agendas: Universal Health Coverage, the International Health Regulations and Strengthening Health Systems.
African health ministers meeting in Victoria Falls, Zimbabwe, for the 67th Session of the WHO Regional Committee have agreed on ten priority actions to guide countries on the elimination of the yellow fever epidemics by 2026.
This endorsement reflects the strong political commitment of African nations to controlling yellow fever as a whole region.
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.
