Why Some Ebola Strains Are More Dangerous Than Others

CHEMISTRY WORLD by Christopher Barnard             June 17, 215
The virulence of Ebola virus strains appears to be innately linked to the degree of disorder in proteins that form their nucleocapsids. Computational analysis has revealed that strains responsible for the most lethal outbreaks of Ebola show significantly higher levels of intrinsic protein disorder than less virulent strains, in a discovery that could constitute a major breakthrough in understanding the pathogen’s behaviour.

With over 27,000 confirmed, probable and suspected cases and more than 11,000 fatalities worldwide, the ongoing Ebola outbreak has resulted in considerably more casualties since late 2013 than all other outbreaks combined. There are no effective treatments or vaccines against the haemorrhagic fever that evinces Ebola infection; however, strains of the virus with drastically different virulence have emerged since the first outbreak in 1976, with fatality rates ranging from 25 to 90%.

Sierra Leone: Mothers Refuse to Vaccinate Children for Fear of Resurgent Ebola

BREITBART.COM  by Frances Martel                                             June 16, 2015

Doctors in Port Loko, a northwestern region of Sierra Leone outside Freetown, are reporting a significant drop in the number of mothers bringing their children to hospitals for routine vaccinations. The mothers, they say, fear exposing their children to a resurgent Ebola virus, and in keeping them from hospitals are risking triggering the spread of polio or measles.

Ebola vaccines in limbo expose need for more speed in trials

REUTERS by Kate Keller and Ben Hirschler                                      June 17, 2015

LONDON --Drugmakers' plans to conduct vast clinical trials to test and hopefully validate the first Ebola vaccines have been thwarted by success in beating back the deadly epidemic in West Africa.

GlaxoSmithKline, Merck and Johnson & Johnson are struggling to recruit volunteers with enough exposure to the disease to prove whether their vaccines are doing the job and preventing infection.

The story might have been very different with just another three or four months of disease spread, underscoring the need to act more quickly to develop vaccines for emerging diseases....

Guinea, where Ebola is still infecting new victims, as "the only hope" for showing efficacy, according to Kieny and to Adrian Hill, director of the Jenner Institute at Britain's Oxford University.

The WHO is overseeing the so-called ring vaccination study in Guinea in which close contacts and family around each new case of Ebola are vaccinated -- either immediately or after a three-week delay -- to see if the shot offers protection.

Turn on the taps to defeat the next Ebola

IRIN by Jennifer Lazuta                                 June 15, 2015

DAKAR, Senegal - It is a cruel irony that many of the top doctors and nurses in Guinea, Liberia and Sierra Leone will not be around to help rebuild their health systems in the wake of Ebola, having succumbed themselves to the virus.

 For those that are, the biggest challenges are likely to be electricity, sanitation, and, most of all, water.

“How is it possible to build, or rebuild, as you may call it, a health institution or hospital without [access to] water, which serves as a major catalyst to run the facility?” asked Moses Tamba, a spokesperson for Liberia’s Ministry of Public Works. “It is not possible. You need water....”

Health Authorities Repeating Mistakes in Ebola Fight: MSF

AFP - June 13, 2015

Dakar (AFP) - Health authorities are repeating the mistakes of the past in combatting Ebola, more than a year after its onset in Guinea and Sierra Leone, the international president of Doctors Without Borders (MSF) warned.

Joanne Liu's remarks on Saturday come a day after Sierra Leone imposed a three-week daytime curfew in the last Ebola-hit areas in a bid to curb a resurgence of the deadly virus, which has killed about 3,900 people in the country.

Neighbouring Liberia was declared Ebola-free in May, but hopes that Sierra Leone and Guinea would quickly follow suit have been dashed in recent weeks.

"We are still making the same mistakes as we did in the past," said Liu.

Favipiravir—a prophylactic treatment for Ebola contacts?

THE LANCET byMichel Van Herp, Hilde Declerck and Tom Decroo June 13, 2015

.. the efficacy of candidate Ebola vaccines for primary prevention has not been proven.2 Furthermore, in communities in which Ebola transmission might be ongoing, an important question is: how will such a vaccination be perceived if a vaccinated person develops Ebola? Such a scenario is possible in people who contract Ebola virus before vaccination. If a person is infected with Ebola virus before vaccination, the vaccine might have a post-exposure prophylactic effect. However, how effective this prophylaxis might be is unknown.2 Moreover, if someone is infected more than 48 h before vaccination, the post-exposure prophylactic effect is likely to be insufficient, leading to possible development of Ebola after vaccination. This scenario is likely to result in serious issues relating to community trust and acceptance of an Ebola vaccine.3 How to exclude Ebola among people presenting with post-vaccination fever is also an issue.2

The Case for Improved Diagnostic Tools to Control Ebola Virus Disease in West Africa and How to Get There

PLOS by Arlene C. Chua,Jane Cunningham,Francis Moussy, Mark D. Perkins,and Pierre Formenty      June 11 2015

 ...Since the identification of Ebola in Guinea in March 2013, rapid deployment of international mobile laboratories through WHO networks—Global Outbreak Alert and Response Network (GOARN) [2] and Emerging and Dangerous Pathogens Laboratory Network (EDPLN) [3]—has been vital to outbreak control operations. Deployable laboratories from multiple international organizations have been established near Ebola treatment centers (ETC) in Guinea, Liberia, and Sierra Leone....

However, several technical and social factors conspire to delay diagnosis, starting with weak surveillance systems and slow patient access to centralized ETCs. While the mean processing time is 5 hours (time difference from when samples are received in the laboratory to when they are tested), there is a marked difference in the time from when the samples are collected from suspected patients to the time they are received by the laboratory

Home > Health Sierra Leone Leader Imposes Curfew in Bid to Halt Ebola

 

FREETOWN -- Sierra Leone's president imposed new restrictions Friday preventing people from entering or leaving two chiefdoms in the northern part of the country that are experiencing a resurgence of Ebola.

While neighboring Liberia has defeated Ebola, Sierra Leone and Guinea have continued to battle new cases, particularly along the border where those two countries meet.

Sierra Leone had 15 news cases in the week ending June 7, according to the World Health Organization, the highest weekly total since late March.

On Friday, President Ernest Bai Koroma said people would be barred from entering or leaving the affected parts of Kambia and Port Loko districts in northern Sierra Leone. A 21-day curfew also will be in effect from 6 p.m. to 6 a.m., government officials said, though the public health benefit of such a limited measure was not immediately clear.

How close is the Ebola vaccine?

PUBLIC BROADCASTING CORP by Caleb Hellerman         June 11, 2015

The quest for an Ebola vaccine has been a journey filled with excruciating delays and mad dashes. The latest outbreak in West Africa caused governments and drug companies to jumpstart research that had languished back when the threat of Ebola wasn’t big enough to sustain a commercial market. (Prior to 2013, the virus had sickened fewer than 2,300 people in known history). Human safety trials of two vaccines began last summer — each being given to a small group of healthy volunteers. When no major side effects were apparent, health officials scrambled to launch larger tests in the countries that were most affected by Ebola.
