WHO: Ebola Situation Report – 17 June 2015
[Excerpts]
SUMMARY
:: There were 24 confirmed cases of Ebola virus disease (EVD) reported in the week to 14 June, compared with 27 cases the previous week. In Guinea, 10 cases were reported from 4 prefectures (Boke, Conakry, Dubreka, and Forecariah). A total of 14 cases were reported from 2 districts (Kambia and Port Loko) in Sierra Leone.
:: Of 76 confirmed cases reported from Guinea and Sierra Leone in the 21 days to 14 June, 69 (91%) have come from 3 prefectures in Guinea (Boke, Dubreka, and Forecariah) and 2 districts in Sierra Leone (Kambia and Port Loko). Most (55) of these 69 cases came from well-characterised chains of transmission, and arose among registered, monitored contacts of previous cases. Each of these cases presents a risk of further transmission, but in most instances that risk is well understood and can be planned for accordingly. However, 14 of those 69 cases, and 5 of the 7 cases that were reported from other prefectures and districts during the same period, arose from unknown sources of infection, and/or are associated with a large number of high-risk contacts, some of whom it was not possible to trace. Effectively managing the risks associated with cases such as these will be crucial to getting to zero. To that end, a package of enhanced surveillance and response measures has been introduced in both Guinea and Sierra Leone:
…In Guinea, health checkpoints have been established in the western prefectures of Boke and Coyah. A 6-day door-to-door case-finding and sensitization campaign was carried out in Dubreka from 7 June, leading to the detection of 1 confirmed case. In addition, intensive investigations are underway to trace a number of high-risk contacts associated with 3 cases reported from the Guinean capital, Conakry, over the past 2 weeks. All of the 3 cases acquired infection outside the capital.
…In Sierra Leone, a large-scale operation is planned in the districts of Kambia and Port Loko, aimed at ending the secret movement of cases, contacts, and dead bodies that has propagated transmission over the past 2 months. Measures include broadened criteria for identifying and tracing contacts, improved incentives to increase compliance with quarantine measures and encourage the timely reporting and isolation of cases, and expanded use of rapid diagnostic tests.
:: As at 14 June, there were 1927 contacts being monitored across 8 prefectures in Guinea. In Sierra Leone, 443 contacts were under follow-up in 3 districts. A total of 660 laboratory samples were tested in Guinea in the week to 14 June: 4% tested positive. Over the same period, 1787 new samples were tested in Sierra Leone, with less than 1% testing positive.
:: In Guinea there were a total of 15 unsafe burials in the week to 14 June, representing 4% of 357 community deaths. In the week to 7 June, 1 unsafe burial was reported in Sierra Leone.
COUNTRIES WITH WIDESPREAD AND INTENSE TRANSMISSION
:: There have been a total of 27,305 reported confirmed, probable, and suspected cases of EVD in Guinea, Liberia and Sierra Leone (figure 1, table 1), with 11,169 reported deaths (this total includes reported deaths among probable and suspected cases, although outcomes for many cases are unknown). A total of 10 new confirmed cases were reported in Guinea and 14 in Sierra Leone in the 7 days to 14 June. The outbreak in Liberia was declared over on 9 May.

WHO: Staying at zero: Keeping Ebola out of Liberia
18 June 2015 — Over a month has passed since Ebola transmission ceased in Liberia. This hard-fought achievement is still being celebrated across the country, where nearly 11 000 people became infected with the virus and 4 800 died. Liberia is still urging communities not to let their guard down until Ebola is gone from the region. Liberia is working closely with WHO and partners to keep Ebola from re-emerging.

Study of Ebola survivors opens in Liberia
Trial to examine long-term health effects of Ebola virus disease
June 17, 2015
The Liberia-U.S. clinical research partnership known as PREVAIL has launched a study of people in Liberia who have survived Ebola virus disease (EVD) within the past two years. The study investigators hope to better understand the long-term health consequences of EVD, determine if survivors develop immunity that will protect them from future Ebola infection, and assess whether previously EVD-infected individuals can transmit infection to close contacts and sexual partners. The study, sponsored by the Ministry of Health of Liberia and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, will take place at various sites in Liberia and is expected to enroll approximately 7,500 people, including 1,500 people of any age who survived EVD and 6,000 of their close contacts.
“The clinical course of Ebola virus disease is reasonably well-understood, but we still have much to learn about the long-term health effects of the illness in those who recover,” said NIAID Director Anthony S. Fauci, M.D. “To unravel the many unknowns, we have expanded the focus of our partnership with Liberia’s Ministry of Health to include research on the long-term health effects of Ebola virus disease, in addition to our ongoing efforts to find an effective preventive vaccine and treatments for Ebola virus disease.”…

Update on Ebola treatment trial in Sierra Leone
A clinical trial of a potential treatment for Ebola, called TKM-Ebola-Guinea, is no longer recruiting patients after reaching a pre-defined endpoint. Early results indicated that continued enrolment to the study, which has been running since March 2015 in Sierra Leone, was unlikely to demonstrate an overall therapeutic benefit to patients.
The research team is currently analysing the data collected during the trial and will make the results available as soon as possible. The single-arm phase II study (RAPIDE-TKM), is led by Professor Peter Horby of the University of Oxford on behalf of the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) in collaboration with the College of Medicine and Allied Health Sciences in Sierra Leone. The study is funded by the Wellcome Trust.
Professor Horby, Associate Professor of Infectious Diseases and Global Health at the University of Oxford and Chief Investigator of the study, said: “It is a great tribute to our colleagues in Sierra Leone that the trial has been run so efficiently and that we now have substantial experience on the use of TKM-Ebola-Guinea in patients with Ebola.
“While the trial has reached a statistical endpoint, and has therefore completed, final conclusions on the efficacy and tolerability of the drug must await full analysis of the data.”
TKM-Ebola-Guinea, is a synthetic small interfering RNA (siRNA) therapeutic developed and manufactured by Tekmira Pharmaceuticals. It is one of a number of candidate Ebola treatments to be evaluated through the Wellcome Trust Ebola therapeutics platform, which was set up in September 2014 to enable multiple partners to quickly establish clinical trials at existing Ebola treatment centres.

As Ebola Crisis Wanes, a Mixed Picture of Economic Recovery for Households in Sierra Leone
Results from third round of mobile-phone surveys show progress since February
WASHINGTON, June 15, 2015—Employment in Sierra Leone has returned to pre-crisis levels, though earnings and hours worked still lag behind. This is according to respondents in the latest round of high-frequency mobile-phone surveys, led by Statistics Sierra Leone with support from the World Bank Group, assessing how Ebola is impacting people’s livelihoods. The survey contacted a sample of 1,715 households during May, 2015, which represents 41 percent of the 4,199 households covered in the baseline, nationally-representative Labor Force Survey conducted in July and August 2014. “Sierra Leone is working tirelessly to get to zero cases of Ebola,” said Francis Ato Brown, World Bank Group Country Manager for Sierra Leone. “Our job has to be not only to support the country in eradicating Ebola, but also to look toward economic recovery and toward mitigating the short-, medium-, and long-term impacts…
