Robust surveillance needed to detect re-emergence of Ebola

27 November 2015 -- A cluster of three confirmed cases of Ebola virus disease (EVD) in Liberia underscore the importance of robust surveillance measures to ensure the rapid detection of any reintroduction or re-emergence of EVD in currently unaffected areas. The first-reported case was a 15-year-old boy who tested positive for EVD on 19 November. Two other members of the family – the boy’s 8-year old brother and his 40-year-old father – subsequently tested positive.

Ebola - Then and Now

18 November 2015 -- This week Guinea reported no new cases of Ebola (to 15 November) and has interrupted transmission of the virus. But one year ago, the Ebola outbreak was generating so many new cases, had spread to so many countries that the world was terrified, fearing that this was the pathogen that would overwhelm humanity. Strong leadership, responsiveness to cultures and innovation have turned the tide.

Then and Now - What a difference a year has made

5 November 2015 -- One year ago, the West African Ebola outbreak was generating so many new cases, had spread to so many countries that the world was terrified. Many feared that the Ebola virus was the pathogen that would overwhelm humanity. Now, one year later that terror has been replaced by confidence that strong leadership, adaptation of the response to cultures and environments and innovation have turned the tide. Liberia has interrupted transmission and Sierra Leone is close to achieving that milestone. Guinea is still recording cases but in low numbers. Here in the words of those who have been fighting Ebola are the impressions of what it was like a year ago and what the Ebola outbreak looks like now.

Ebola response phase 3: Achieving and sustaining a resilient zero

18 September 2015 -- The Ebola Phase 3 framework incorporates new knowledge and tools into the ongoing Ebola response and recovery work to achieve and sustain a "resilient zero". Phase 3 builds upon the rapid scale-up of treatment beds, safe and dignified burial teams, and behaviour change capacities during Phase 1; and the enhanced capacities for case finding, contract tracing, and community engagement during Phase 2. It includes new developments and breakthroughs in Ebola control, from vaccines, diagnostics and response operations to survivor counselling and care.
