UNITED NATIONS-- The U.N. Ebola chief said Thursday it will take several more months before the outbreak in West Africa is under control, an assessment that makes clear the World Health Organization's goal of isolating 100 percent of Ebola cases by Jan. 1 won't be met.

Dr. David Nabarro said there has been "a massive shift" over the last four months in the way affected governments have taken the lead in responding to the epidemic, communities are taking action and the international community has pitched in.

But he said greater efforts are needed to combat Ebola in western Sierra Leone and northern Mali, to reduce the number of new cases in Liberia and to limit transmission to Mali.

WHO conceded that it didn't meet an interim Dec. 1 target of isolating 70 percent of Ebola patients and safely burying 70 percent of victims in hardest-hit Sierra Leone. But it hasn't made clear what that means for its Jan. 1 goal, which it set in September. It has acknowledged that its patchy data could compromise the goal, since the agency does not know how many Ebola patients there actually are and is unable to track all of their contacts.

A total of 17 942 confirmed, probable, and suspected cases of Ebola virus disease (EVD) have been reported in five affected countries (Guinea, Liberia, Mali, Sierra Leone, and the United States of America) and three previously affected countries (Nigeria, Senegal and Spain) up to the end of 7 December. There have been 6388 reported deaths.

Reported case incidence is slightly increasing in Guinea (103 confirmed and probable cases reported in the week to 7 December), declining in Liberia (29 new confirmed cases in the 3 days to 3 December), and may still be increasing in Sierra Leone (397 new confirmed cases in the week to 7 December). The case fatality rate across the three most-affected countries in all reported cases with a recorded definitive outcome is 76%; in hospitalized patients the case fatality rate is 61%.

The means by which Ebola virus transmits through direct contact with body fluids of infected individuals is well covered in scientific literature. But little is known about the life the virus has - if any - outside the body. For example, does Ebola remain active on glass surfaces and countertops? Does it persist in sewage and wastewater systems?

Such questions are rarely addressed in currently published literature, say engineers from the University of Pittsburgh (Pitt) and Drexel University, Philadelphia.

A team of engineers says scientific literature contains little information about how well Ebola survives outside the body. They call for research to investigate its persistence in the environment so correct guidance can be given on disinfection and waste handling.

They report their findings - or lack of them - and why it is important to find some answers, in a paper published in the journal Environmental Science & Technology Letters....

The Ebola crisis in West Africa is approaching the one-year mark, with no clear end in sight. At present, fewer than one in five people with Ebola is diagnosed within two days of becoming infectious, according to the World Health Organization (WHO). Yet in the absence of a safe and effective vaccine, the only way to end the epidemic is to quickly identify and quarantine people who have been infected.

A major problem is that relatively few laboratories in West Africa have the necessary equipment and personnel to test blood samples from people thought to have Ebola (see ‘Delayed diagnoses’). But that could soon change. Experts are gathering in Geneva, Switzerland, on 12 December to work out which diagnostic tools could be used wherever Ebola strikes.
