WHO: Ebola Situation Report – 6 May 2015
[Excerpts]
SUMMARY
:: A total of 18 confirmed cases of Ebola virus disease (EVD) was reported in the week to 3 May: Guinea and Sierra Leone each reported 9 cases. This is the lowest weekly total this year, and comes after a month-long period during which case incidence fluctuated between 30 and 37 confirmed cases per week. That both countries have each reported fewer than 10 cases is encouraging, but it is important to guard against complacency. Liberia has reported fewer than 10 cases per week since the start of January this year, but the outbreak will be declared to have ended only if no new cases are reported up to 9 May, which marks 42 complete days since the burial of the last confirmed case…

COUNTRIES WITH WIDESPREAD AND INTENSE TRANSMISSION
:: There have been a total of 26,593 reported confirmed, probable, and suspected cases of EVD in Guinea, Liberia and Sierra Leone (figure 1, table 1), with 11,005 reported deaths (outcomes for many cases are unknown). A total of 9 new confirmed cases were reported in Guinea, 0 in Liberia, and 9 in Sierra Leone in the 7 days to 3 May.
The Ebola outbreak in Liberia is over
WHO statement
9 May 2015
Today, 9 May 2015, WHO declares Liberia free of Ebola virus transmission. Forty-two days have passed since the last laboratory-confirmed case was buried on 28 March 2015. The outbreak of Ebola virus disease in Liberia is over.

Interruption of transmission is a monumental achievement for a country that reported the highest number of deaths in the largest, longest, and most complex outbreak since Ebola first emerged in 1976. At the peak of transmission, which occurred during August and September 2014, the country was reporting from 300 to 400 new cases every week…
