LONDON/DAKAR--A recent sharp drop in new Ebola infections in West Africa is prompting scientists to wonder whether the virus may be silently immunizing some people at the same time as brutally killing their neighbors.

So-called "asymptomatic" Ebola cases - in which someone is exposed to the virus, develops antibodies, but doesn't get sick or suffer symptoms - are hotly disputed among scientists, with some saying their existence is little more than a pipe dream.
Ebola is a "zoonotic" disease: the virus starts out in animal populations - believed to be fruit bats - and then spills over into humans. Now, a new study that investigates landscape features of where spillover occurs suggests human population density and vegetation cover may be important factors.
The researchers examined landscape features of precise geo-locations of Ebola spillover into humans.
The study is the work of two researchers from SUNY Downstate Medical Center in Brooklyn, NY, who write about their findings in the open-access journal PeerJ.
First author Michael G. Walsh, assistant professor of epidemiology and biostatistics in SUNY Downstate's School of Public Health, says they found significant interaction between density of human populations and the extent of green vegetation cover in the parts of Africa that have seen outbreaks of Ebola virus disease (EVD).
BBC by Tulip Mazumdar Jan. 7, 2015 FREETOWN, Sierra Leone --
...One factor crucial to ending the outbreak is the safe burial of Ebola victims, because their bodies are particularly toxic.
The UK is funding more than 100 burial teams in Sierra Leone. Tulip Mazumdar spent the day with one of them, the Sierra Leone Red Cross Burial Team 9 in the capital Freetown. Here she describes her day....
The team is called to collect a body and, before it is removed, the group takes a moment to pray
Each burial team had around 10 people, including family liaison officers, disinfectant sprayers and drivers....
These were not highly trained medics or undertakers used to seeing dead bodies. They were people from the community, for example students and other volunteers. Depending on their job they are being paid approximately $10 (£6.60) a day.This is considered a very good wage in a country where most people survive on much less.

This is the hospital where he works as general surgeon and the head of Infection Prevention Control. It's also where he came down with Ebola on August 2.
He says his days in treatment were "a living hell." And the experience has changed his view of the world — and the way he treats patients.

Ban was speaking in Guinea on the second day of a whistle-stop tour aimed at thanking healthcare workers of the countries at the heart of the epidemic....
Ban's tour began in Liberia and Sierra Leone on Friday and will end later on Saturday in Ghana, site of the U.N. Ebola response mission (UNMEER), after a visit to Mali.
"There should be no discrimination for those who have been working or helping with Ebola. Those people are giving all of themselves," Ban told U.N. officials in Conakry.
CHICAGO -- The U.S. Department of Health and Human Services on Tuesday offered liability protections to drugmakers rushing to develop Ebola vaccines and urged other countries to follow suit.
Health and Human Services (HHS) Secretary Sylvia Burwell made the announcement as part of the Public Readiness and Emergency Preparedness (PREP) Act in a move aimed at encouraging the development and availability of experimental Ebola vaccines.
The declaration provides immunity under U.S. law against legal claims related to the manufacturing, testing, development, distribution, and administration of three vaccines for the Ebola virus. However, it does not provide immunity for a claim brought in a court outside the United States...

...Studying investigational therapies for EVD presents scientific, practical, and ethical challenges. Not surprisingly, there has been substantial debate about the best and most appropriate study approaches.2,3 It is generally agreed that a trial with a concurrent control group, in which patients are randomly assigned to receive the test drug plus the best available supportive care (BASC) or to BASC alone, would be the most efficient and reliable way to evaluate the safety and effectiveness of candidate products.
Some people in the health care community, however, have argued against such trials, urging instead use of a historical control — that is, making investigational drugs as widely available as their supply allows and then comparing mortality rates among treated patients with rates that would have been expected absent the drugs, on the basis of past experience with EVD.
“The security council expresses its continued concern about the detrimental effect of the isolation of the affected countries as a result of trade and travel restrictions imposed on and to the affected countries as well as acts of discrimination against the nationals of Guinea, Liberia, Mali and Sierra Leone,” said Julia Bishop, the Australian foreign mniister who was presiding over the session Thursday.
The council statement also described the Ebola outbreeak in Africa as "a threat to international peace and security..."

Quicker and simpler diagnostic tests for Ebola could go a long way in helping break chains of disease transmission in West Africa's outbreak region, the World Health Organization (WHO) said today, as it unveiled two new initiatives to expedite their development.
The WHO said it hopes new efforts—similar to those under way to test and deliver an Ebola vaccine—can compress the development of a rapid test in months instead of years.

Standard reverse-transcriptase polymerase chain reaction (RT-PCR) tests used in mobile and other labs in the outbreak are very accurate when conducted by trained staff, but they require a full tube of blood, take 2 to 6 hours to get a result, and costs around $100 per test, the WHO said today in a statement....
