At present, it is difficult to measure directly the proportion of patients who are isolated. Usually, information from clinical investigation forms could be used to provide an accurate estimate, but inconsistencies in the way different clinical investigation teams interpret and define when and how a patient is hospitalized and isolated mean that this information is not reliable enough at present to draw any conclusions about isolation.
The most robust method of estimating isolation currently available is to use the capacity to treat and isolate patients by geographical area as a proximate measure of the proportion of EVD cases who are isolated. This can be achieved by dividing the number of available EVD-treatment beds by the number of reported cases over a given period of time in a given location, taking account of varying patterns of health-seeking behaviour (e.g., in areas with poor transport links, cases are unlikely to travel large distances for diagnosis and treatment).
Using this proximate measure of isolation at a national level, all three intense-transmission countries currently have the capacity to isolate all reported cases. In Guinea (table 2) there are 2.3 available beds per reported probable and confirmed EVD case; in Liberia (table 3) there are 11.7 beds for every probable and confirmed case, and in Sierra Leone there are 1.5 beds for every probable and confirmed case (table 4). However, these numbers are, to a degree, an oversimplified representation of a more complex situation within each country.
Supposedly the epidemic has practically stopped in Liberia but is surging out-of-control again in Sierra Leone. Any figures?

Ebola Death Toll in Three West African Countries Most Hit by Virus Nears 7,000 WHO Says 6,928 People Died of Ebola in Guinea, Liberia and Sierra Leone
Looks like WHO is playing around with the numbers again.
The UN's Ebola czar on Tuesday hailed widespread progress in the fight against the deadly virus, but warned the outbreak was still surging in western Sierra Leone and northern Guinea.
"We know the outbreak is still flaming strongly in western Sierra Leone and some parts of the interior of Guinea," David Nabarro, the UN coordinator on Ebola, told reporters in Geneva.
He said more foreign health workers and specialists were needed in the areas where the disease was still spreading quickly, as were more treatment units and beds.
Sierra Leone now leads Liberia as having the highest number of deaths from Ebola and western health experts say the virus there is still spreading. Rob Muir reports.
The United Nations says Ebola has now claimed more lives in Sierra Leone than in any other country. According to the UN' s David Nabarro, the situation is getting worse.
“A total of 18,464 confirmed, probable, and suspected cases of Ebola virus disease (EVD0 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) as of December 14. There have been 6,841 reported deaths,” the WHO’s report said.
