Mapping the Zoonotic Niche of Ebola Virus Disease in Africa

Ebola virus disease (EVD) is a complex zoonosis that is highly virulent in humans. The largest recorded outbreak of EVD is ongoing in West Africa, outside of its previously reported and predicted niche. We assembled location data on all recorded zoonotic transmission to humans and Ebola virus infection in bats and primates (1976–2014). Using species distribution models, these occurrence data were paired with environmental covariates to predict a zoonotic transmission niche covering 22 countries across Central and West Africa. Vegetation, elevation, temperature, evapotranspiration, and suspected reservoir bat distributions define this relationship. At-risk areas are inhabited by 22 million people; however, the rarity of human outbreaks emphasises the very low probability of transmission to humans. Increasing population sizes and international connectivity by air since the first detection of EVD in 1976 suggest that the dynamics of human-to-human secondary transmission in contemporary outbreaks will be very different to those of the past.

Use of Group Quarantine in Ebola Control — Nigeria, 2014

Morbidity and Mortality Weekly Report (MMWR)

On July 20, 2014, the first known case of Ebola virus disease (Ebola) in Nigeria, in a traveler from Liberia  led to an outbreak that was successfully curtailed with infection control, contact tracing, isolation, and quarantine measures coordinated through an incident management system.

During this outbreak, most contacts underwent home monitoring, which included instructions to stay home or to avoid crowded areas if staying home was not possible. However, for five contacts with high-risk exposures, group quarantine in an observation unit was preferred because the five had crowded home environments or occupations that could have resulted in a large number of community exposures if they developed Ebola.

The Origins and Evolution of the Ebola Epidemic in West Africa

Investigations yield insights into Ebola outbreak's early months

cidrap.umn.edu - by Lisa Schnirring - December 30, 2014

With West Africa's Ebola epidemic passing the 1-year mark, two new reports yielded details about factors that fueled the event, including bats in a hollow tree that may have infected the index patient, a young Guinean child, and a silent chain of transmission that caused the disease to flare again in May after cases had sharply dropped off.

Ebola Survivor Corps Establishment Guidance Toolkit

submitted by Novil Wijesekara

communityresiliencecenter.org

Ebola virus disease (EVD), formerly known as Ebola hemorrhagic fever, is a severe, illness in human with average case fatality rate of around 50% (range 25%-90%). At present, survivors of EVD face psychological effects, social isolation and serious repercussions on health care seeking behavior for EVD.  Ebola Survivor Corps is a comprehensive and sustainable program aimed at getting survivors of EVD back to their communities and society as helpers, advocates, champions and heroes of health and development.

Vision of Ebola Survivor Corps:

A world with zero discrimination for Ebola Survivors

Mission of Ebola Survivor Corps:

To establish a comprehensive and sustainable social organization with Ebola Survivors at the heart for reintegrating, empowering and engaging Ebola Survivors as leaders, advocates, champions and heroes of health and development.

What worked in controlling the Ebola outbreak in West Africa

One Lesson: Rush to Help, not to declare victory

EDITORIAL    THE WASHINGTON POST                                Jan. 31, 2015

THE WORLD’S tardy response to the Ebola virus outbreak in West Africa, which has killed 8,810 people, demands that lessons be learned.

 Toward that end, a fresh batch of scientific reports has emerged in recent days to guide future responses. The World Health Organization, which stumbled in the initial period, seems to be recognizing its mistakes and looking for ways to correct them.... it is vital to keep medical interventions in place for long periods — and a big mistake to declare victory too early. The research also shows that most transmission of Ebola occurred in families....

Estimating Food Consumption and Poverty Indices with Mobile Phone Data

Recent studies have shown the value of mobile phone data to tackle problems related to economic development and humanitarian action. In this research, we assess the suitability of indicators derived from mobile phone data as a proxy for food security indicators. We compare the measures extracted from call detail records and airtime credit purchases to the results of a nationwide household survey conducted at the same time. Results show high correlations (> .8) between mobile phone data derived indicators and several relevant food security variables such as expenditure on food or vegetable consumption. This correspondence suggests that, in the future, proxies derived from mobile phone data could be used to provide valuable up-to-date operational information on food security throughout low and middle income countries.

Do Ebola educators make a difference?

THE GUARDIAN by                        Jan. 29. 2015

FREETOWN, Sierra Leone -- The initial Ebola case in Tambakha [a remote chiefdom near the Guinea border] coincided with the proper training of the first set of Ebola educators. They were deployed in mid-October to educate local people on the prevention and control of Ebola and to help monitor the advent of newcomers into their communities, possible carriers.

This event has concluded. View the replay above.

worldbank.org - Date: January 27th 2015 - Location: Georgetown University & Online Time: 4:00 p.m. - 5:00 p.m. ET (21:00 - 22:00 GMT)

Jim Yong Kim, President of the World Bank Group, will deliver Georgetown’s inaugural Global Futures lecture.

The lecture, “Lessons from Ebola: A post-2015 strategy for pandemic response,” will kick off a semester-long conversation about the “Global Future of Development” at Georgetown as part of the university’s new Global Futures Initiative.

His talk on Jan. 27 will connect ongoing efforts to stop the spread of infection in West Africa with longer-term efforts to improve public health systems that support economic and social development in countries vulnerable to future pandemics.

Meant to Keep Malaria Out, Mosquito Nets Are Used to Haul Fish In

 

Millions of mosquito nets are given out fight to malaria in Africa, yet many faced with hunger use them as fish nets, creating potential environmental problems. Video by Ben C. Solomon on Publish Date January 24, 2015. Photo by Uriel Sinai for The New York Times.

NEW YORK TIMES   by Jeffery Gettleman                           Jan. 25, 2015

BANGWEULU WETLANDS, Zambi --Across Africa, from the mud flats of Nigeria to the coral reefs off Mozambique, mosquito-net fishing is a growing problem, an unintended consequence of one of the biggest and most celebrated public health campaigns in recent years.

The nets have helped save millions of lives, but scientists worry about the collateral damage: Africa’s fish.
