The number of cases in the Ebola outbreak has exceeded 10,000, with 4,922 deaths, the World Health Organization says in its latest report.
Only 27 of the cases have occurred outside the three worst-hit countries, Sierra Leone, Liberia and Guinea.
Those three countries account for all but 10 of the fatalities.
Mali became the latest nation to record a death, a two-year-old girl. More than 40 people known to have come into contact with her have been quarantined.
The latest WHO situation report says that Liberia remains the worst affected country, with 2,705 deaths. Sierra Leone has had 1,281 fatalities and there have been 926 in Guinea.
Nigeria has recorded eight deaths and there has been one in Mali and one in the United States.
The WHO said the number of cases was now 10,141 but that the figure could be much higher, as many families were keeping relatives at home rather than taking them to treatment centres. It said many of the centres were overcrowded.
And the latest report also shows no change in the number of cases and deaths in Liberia from the WHO’s previous report, three days ago.
Eight countries have registered cases in the outbreak. In West Africa, Senegal and Nigeria have now been declared virus-free by the WHO.
‘Facts, not fear’
In the US, the governors of the states of New York, New Jersey and Illinois have ordered a mandatory 21-day quarantine period for all doctors and other travellers who have had contact with Ebola victims in West Africa.
Anyone arriving from affected West African countries without having had confirmed contact with Ebola victims will be subject to monitoring by public health officials.
