Up to 4 November, 4,960 people had been reported as having died from the disease in five countries; Liberia, Guinea, Sierra Leone, Nigeria and the United States. A further death has been reported in Mali.
The total number of reported cases is in excess of 13,000.
The World Health Organization (WHO) admits the figures are underestimates given the difficulty collecting the data and warns there could be as many as 20,000 cases by the end of November if efforts to tackle the outbreak are not stepped up.

Emergency declared
Director of the Centers for Disease Control and Prevention (CDC) in the US, Thomas Frieden, said in October that the Ebola outbreak in West Africa is unlike anything since the emergence of HIV/Aids.
The WHO has declared the outbreaks in Nigeria and Senegal officially over, as there have been no new cases reported since 5 September.
Medical charity Medecins Sans Frontieres (MSF), which employs thousands of staff across West Africa battling the disease, confirmed this week that Liberia has seen a significant reduction in the number of new Ebola cases.
Liberia, the worst-hit country of the Ebola outbreak with more than 2,500 deaths, reported that two-thirds of the 696 beds in the country's treatment centres were empty.
MSF warned that the disease could "flare up" again, pointing to Guinea, where the number of cases is rising again despite two significant lulls. Cases are also still on the rise in Sierra Leone.
Current outbreak
Researchers from the New England Journal of Medicine
have traced the outbreak to a two-year-old toddler, who died on 6
December 2013 in Meliandou, a small village in south-eastern Guinea.
In March, hospital staff alerted Guinea's Ministry of Health and then the charity Medecins Sans Frontieres (MSF). They reported a mysterious disease in the south-eastern regions of Gueckedou, Macenta, Nzerekore, and Kissidougou.
It caused fever, diarrhoea and vomiting. It also had a high death rate. Of the first 86 cases, 59 people died.
The WHO later confirmed the disease as Ebola.

Disease spreads
Gueckedou is a major regional trading centre and, by the end
of March, Ebola had crossed the border into Liberia and it was confirmed
in Sierra Leone in May.
In June, MSF described the Ebola outbreak as out of control.
Nigeria had its first case of the disease in July and in the same month two leading doctors died from Ebola in Liberia and Sierra Leone. Senegal reported its first case of Ebola on 29 August. A young man from Guinea had travelled to Senegal despite having been infected with the virus, officials said.
The first case of the deadly virus diagnosed on US soil was announced on 1 October. Thomas Eric Duncan, 42, who contracted the virus in Liberia before travelling to the US, died on 8 October.
He had not displayed symptoms of the disease until 24 September, five days after his arrival. Other people with whom he came into contact are being monitored for symptoms.

Germany, Norway and France and the UK have all treated patients who contracted the virus in West Africa.
Cumulative deaths up to 4 November
Note: figures are occasionally revised down as suspect or probable cases are found to be unrelated to Ebola
The WHO has published updates on the spread of the virus in each of the countries affected.
The figures given are for "confirmed, probable and suspected" cases and deaths. They have occasionally been revised down to take account of changes in the countries' reporting methods, for example by excluding the "suspected" cases.
2014 outbreak in context Ebola was first identified in 1976 and occurs in regions of sub-Saharan Africa. There are normally fewer than 500 cases reported each year, and no cases were reported at all between 1979 and 1994.
In August 2014 the WHO confirmed a separate outbreak of Ebola in the Democratic Republic of Congo. By the beginning of October there had been 70 cases reported and 43 deaths.
However, the outbreak in DR Congo is a different strain of the virus and unrelated to the epidemic in West Africa, which now dwarfs all previous outbreaks.

The
Ebola outbreak in West Africa was first reported in March 2014, and has
rapidly become the deadliest occurrence of the disease since its
discovery in 1976.
In fact, the current epidemic sweeping across the region has now killed more than all other known Ebola outbreaks combined.Up to 4 November, 4,960 people had been reported as having died from the disease in five countries; Liberia, Guinea, Sierra Leone, Nigeria and the United States. A further death has been reported in Mali.
The total number of reported cases is in excess of 13,000.

In August, the United Nations health agency declared an "international public health emergency", saying that a co-ordinated response was essential to halt the spread of the virus.
By September, WHO director general Margaret Chan said that
the "number of patients is moving far faster than the capacity to manage
them". Director of the Centers for Disease Control and Prevention (CDC) in the US, Thomas Frieden, said in October that the Ebola outbreak in West Africa is unlike anything since the emergence of HIV/Aids.

*In
all but three cases the patient was infected with Ebola while in West
Africa. Infection outside Africa has been restricted to health workers
in Madrid and in Dallas. DR Congo has also reported a separate outbreak
of an unrelated strain of Ebola.

Two
medical workers in Dallas, Texas, who treated Duncan have tested
positive for Ebola since his death and are receiving treatment.
Spanish nurse Teresa Romero was the first person to contract
the virus outside West Africa. She was part of a team of about 30 staff
at the Carlos II hospital in Madrid looking after two missionaries who
returned from Liberia and Sierra Leone after becoming infected.Germany, Norway and France and the UK have all treated patients who contracted the virus in West Africa.
