Is Ebola Here to Stay?

SCIENTIFIC AMERICAN by Dina Fine Maron                                  Dec. 29, 2014
Kisses are at a premium in the capital of Liberia. Even a hug or a handshake between friends is often out of the question. That’s the new normal ever since Ebola began ravaging communities throughout Liberia, Sierra Leone and Guinea. For much of the past year, residents of these west African countries have wondered if daily life will ever be able to return to the way things once were.

And at the heart of the matter is a scientific question: has Ebola now found a permanent foothold among humans?

Experts call for faster mobilisation of “overlooked” survivors to contain Ebola epidemic

OXFORD UNIVERSITY PRESS                                                                                  Dec, 10, 2014

In an editorial published online today in the International Journal of Epidemiology, experts from the Departments of Psychiatry and Epidemiology at Columbia University, New York, are calling for survivors of the Ebola epidemic to be mobilised in a bid to hasten containment of the disease.

We already know that the current Ebola outbreak is unique in its magnitude and for its dispersion in dense, mobile populations. Physicians and nurses face high mortality, and foreign aid in the form of medical supplies and staff continues to be unequal to the scope of the problem. With a case recovery rate of around 30% at the present time in West Africa, survivors already number in the thousands.

WHO: malaria gains 'at risk' in Ebola-affected countries

MEDICAL NEWS TODAY                                                                                                 Dec. 9, 2014

LONDON --Thanks to increased disease control, global deaths to malaria have fallen dramatically, and the number of new cases is steadily declining, say the World Health Organization in a new report. Also, an increasing number of countries are moving toward eliminating the mosquito-borne disease altogether. But the UN agency warns these gains are fragile, and no more so than in countries worse-affected by the Ebola crisis.

 
A new report from the World Health Organization says the number of lives claimed by malaria worldwide fell by 47% between 2000 and 2013, and by 54% in Africa, where the vast majority of deaths occur.

The 2014 World Health Organization (WHO) report says deaths to malaria worldwide fell by 47% between 2000 and 2013. In the WHO African Region, where 90% of deaths to malaria occur, the reduction is 54%.

Rapid Ebola test is focus of NIH grant to Rutgers scientist

REPORTS Of RESEARCH ON TWO METHODS OF RAPID TESTING FOR EBOLA

(Two items, scroll down)

MEDICAL PRESS                                                                                     Dec. 8, 2014

Rutgers researcher David Alland, working with the California biotechnology company Cepheid, has received a grant of nearly $640,000 from the National Institutes of Health to develop a rapid test to diagnose Ebola as well as other viruses that can cause symptoms similar to Ebola.

Alland, a professor of medicine and associate dean for clinical research at Rutgers New Jersey Medical School and the principal investigator of the project, says would be able to take the test to small villages and other remote locations where the spread of Ebola has been especially rampant and diagnose patients where they live...

Number of Ebola deaths could be cut by use of basic measures, say experts

THE GUARDIAN  by in Freetown and
Dec. 5, 2014

Basic medical interventions such as giving Ebola patients rehydration salts and fluids from bigger bags could cut the death toll in west Africa in the absence of a proven cure, experts in tropical diseases write on Friday in the Lancet.

The doctors say it is “therapeutic nihilism” to assume there is no treatment for Ebola just because there are no drugs. It is likely, they say, that many patients die because of dehydration.

Finding the Ebola virus’ vulnerable points

We know what antibodies stop it in its tracks—we now know where they attach.

The latest Ebola outbreak has dwarfed any that have occurred since the discovery of the virus in 1976; previous outbreaks have had lethality rates of up to 90 percent. Yet no vaccines or therapies are currently approved for human use, which limits our ability to treat patients and contain the outbreak. Mixtures of monoclonal antibodies (see sidebar) are a potential treatment option that has been used experimentally.

To halt Ebola's spread, researchers race for data

DISCOVER MAGAZINE    By Kari Lydersen                                                                              Dec. 2, 2014
.....redicting the trajectory of Ebola rather than playing catching-up could do much to help prevent and contain the disease. Some experts have called for prioritizing mobile treatment units that can be quickly relocated to the spots most needed. Figuring out where Ebola is likely to strike next or finding emerging hot spots early on would be key to the placement of these treatment centers.

But such modeling requires data, and lots of it.  And for stressed healthcare workers on the ground and government and non-profit agencies scrambling to combat a raging epidemic, collecting and disseminating data is often not a high priority.

Gates Foundation, other donors launch study of Ebola drugs, survivors' blood, in Africa

ASSOCIATED PRESS                                                                                                  Nov. 18, 2014

A coalition of companies and aid groups announced plans Tuesday to test experimental drugs and collect blood plasma from Ebola survivors to treat new victims of the disease in West Africa.

Plasma from survivors contains antibodies, substances the immune system makes to fight the virus. Several Ebola patients have received survivor plasma and recovered, but doctors say there is no way to know whether it really helps without a study like the one they are about to start within a month.

Bats’ Link to Ebola Finally Solved

 

THE DAILY BEAST                                                                                                           Nov. 11, 2014
By Carfrie Arnold

A new paper outlines five steps required for a virus to ‘spill over’ from bats to humans. But don’t just blame the bats—deforestation and hunting are to blame, too.

These nocturnal fliers might do some good, but their association with night, rabies, and All Things Creepy means that, at best, we tolerate them. Adding to their negative aura is recent research showing that bats can be the source of infectious diseases like SARS and Ebola, as well as lesser-known pathogens like Hendra and Nipah virus.

It’s all too easy to blame bats for causing these human pandemics, including the most recent (and deadliest) Ebola outbreak. After all, these viruses hang out in bats in between outbreaks—trace any outbreak of these viruses back far enough and you will find a bat.

Infection Secrets of Ebola Explained

By attacking the body's first responders, the virus cripples the immune system before it can mount an effective defense

Researchers often describe the battle between the Ebola virus and the humans it occasionally infects as a race—one that people win only if their immune systems manage to pull ahead before the virus destroys too many of their internal defenses. What they may not know is that the virus is a cheat.
