Quick Test for Ebola - MIT

A new paper diagnostic device can detect Ebola as well as other viral hemorrhagic fevers in about 10 minutes. The device (pictured here) has silver nanoparticles of different colors that indicate different diseases. On the left is the unused device, opened to reveal the contents inside. On the right, the device has been used for diagnosis; the colored bands show positive tests.  Photo - Jose Gomez-Marquez, Helena de Puig, and Chun-Wan Yen

Life After Ebola: What It Takes For A Village To Be Resilient

NATIONAL PUBLIC RADIO INTERVIEW by Laura Starecheski                                     Feb. 20, 2015
BARKEDU,  LIBERIA --If you'd like to get an idea of what resilience is all about, take a lesson from Mamuedeh Kanneh.

She lost her husband to Ebola. But she's stayed strong. She's caring for 13 children, her own and orphans whose parents died of the virus.

Mamuedeh Kanneh was married to Laiye Barwor, the man who brought Ebola to Barkedu, Liberia. He died of the virus. She now cares for her children as well as children who lost their parents to the disease. John W. Poole/NPR

Kanneh lives in Barkedu, a village of about 6,000 in northern Liberia. Ebola took more than 150 lives. In her neighborhood there were many deaths, so people in other parts of Barkedu are scared of the orphans.

Kanneh has a strategy to help these children — and the village overall — get back to normal life. She sends the youngsters on errands so people can get used to seeing them and get over their fear. And the children can start to feel they're part of the community again....

Leaders of Ebola Fight at U.N. Express Worry About Eradication

NEW YORK TIMES  by Rick Gladstone                                    Feb. 20, 2015

The top two health officials managing the Ebola epidemic cast doubt Friday on a pledge by West African leaders to reduce new cases to zero by mid-April, and expressed concern about a possible rebound of the disease.

Finishing Off Ebola

NEW YORK TIMES  OP-ED BY Ron Klain, the former White House Ebola response coordinaor                                    FEB. 20, 2015

...The world needs to do a better job of quickly detecting and responding to future outbreaks in unlikely places. The President’s Global Health Security Agenda, the government’s strategy to combat infection disease around the world, will help. But vulnerable countries, including those in Africa, need their own version of our Centers for Disease Control and Prevention, so that they are not so dependent on ours.

For the hardest task of front-line epidemic fighting, our planet is too reliant on courageous and talented — but underfunded, under-equipped and volunteer-dependent — nongovernmental organizations. The world needs a permanent standing force — or a ready reserve that can be quickly organized — of public health emergency responders who have the training, gear and resources to race into a region in the early phases of epidemic control. The United States military cannot do that job every time; future outbreaks might occur in countries where our troops will not be welcomed as they were in West Africa.

Mapping the Zoonotic Niche of Ebola Virus Disease in Africa

submitted by Stephen Morse

elifesciences.org - September 8, 2014 - eLife 2014;3:e04395
DOI: http://dx.doi.org/10.7554/eLife.04395

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.

Ebola: the race to find a cure

 In October, scientists set out to do something unprecedented – conduct a drugs trial during an epidemic to find a treatment for a lethal disease. Could they make history and change the way we deal with outbreaks?

THE GUARDIAN  by Sarah Boseley                           Feb, 17, 2015

In depth description of efforts by a group of Oxford University scientists to run field trials of drugs for use against Ebola.

" ...The little band of scientists had flown to Guinea on 16 October to do something that had never been successfully done before – set up a trial of experimental drugs against an infectious disease in the middle of an epidemic. Because the Ebola virus does not exist at low levels in any population, unless you run a properly conducted trial while the storm is raging, you will never have drugs that are proven to be effective. The Oxford team’s trial would not only aim to find a drug that worked against Ebola but also to establish a blueprint for the way drug trials would be run during outbreaks in the future. This did not just apply to fighting Ebola: if the scientists were successful, their trial would develop protocols for testing drugs for any epidemic, be it Sars or flu...."

UN Mission for Ebola Emergency Response (UNMEER) External Situation Report

UN Mission for Ebola Emergency Response (UNMEER)                                                         Feb. 16, 2015

Conakry, Guinea --Statement issued by the heads of Guinea, Liberia and Sierra Leone upon approving an operational framework designed to reduce new Ebola infections to zero within 60 days.

The framework calls for infection prevention and control, social mobilization, community engagement, surveillance, cross border collaboration. 

The leaders also "advocated for a seamless and responsible exit by international partners dictated by the epidemiology and by the adequate transfer of capacity to national institutions."

The statement includes a list of developments and responses.

WHO May Lose Credibility After Ebola

Agency seeks a new model after flaws revealed by Ebola crisis.

COMMENTARY MEDPAGE TODAY by Michael Smith            Feb. 15, 2015 

As the Ebola epidemic drags on, the World Health Organization is in danger of losing its credibility as a bulwark against infectious disease.

The West African epidemic is a "mega-crisis (that) overwhelmed the capacity of WHO," according to Director-General Margaret Chan, MD, speaking to reporters in late January.

To prevent a similar crisis in the future, Chan has proposed a package of reforms, including a large contingency fund for emergencies, an increase in the number of trained people able to deploy quickly to a crisis site, and structural changes to streamline the famously unwieldy organization.

Whether those get anywhere is the vital question, according to Lawrence Gostin, JD, of the O'Neill Institute for National and Global Health Law at Washington's Georgetown University.

Doctors Who Treat Ebola Feel More Socially Isolated

LIVESCIENCE.COM   by Rachael Rettner                                                                         Feb. 13, 2015

Doctors who take care of very sick Ebola patients may feel socially isolated, but surprisingly, they may not feel more stressed than usual, a new study from Germany suggests.

Researchers surveyed 46 health care workers who treated Germany's first Ebola patient in August 2014, as well as 40 health care workers who worked in the same hospital but did not treat the Ebola patient.

The researchers who did the study hypothesized that the people who treated the Ebola patient would have more symptoms of psychological distress because they were working in a challenging environment that presented a risk that they could become infected with the deadly virus.
