The Ebola virus disease (EVD) outbreak continues to grow, doubling in size approximately every 3 weeks. The latest WHO figures report a total of 7,178 cases and 3,338 deaths up to September 28.

The current EVD outbreak is unprecedented in scale, geographical reach, and impact on the health care systems of the countries involved. The present West Africa outbreak has a higher caseload than all other previous Ebola crises combined.

An estimated 22.34 million people are living in areas where active EVD transmission has been reported, with 4.29 million people living in areas where twenty or more fatalities have been reported.

The large number of cases in high-population density settings and simultaneously  in remote, hard-to-access villages makes the outbreak particularly difficult to contain.

      The concerning trend of infections among health care workers (HCWs) persists, with 377 cases of which 216 have resulted in death. Of the total cases of EVD-infected HCWs, almost 50% have occurred in Liberia. Because of their role as caregivers, women are experiencing the brunt of the disease, making up 75% of all cases.

      A recent study published by the WHO Ebola Response Team forecasts more than 20,000 (5,740 in Guinea, 9,890 in Liberia and 5,000 in Sierra Leone) by beginning of November 2014. 

      In addition to the cases in Guinea, Liberia, Nigeria, Sierra Leone, and one imported case in Senegal (a Guinean citizen who arrived from Guinea), there has now been a documented case in the Unites States of America, of a man returning to the US after visiting his home country of Liberia. 

      Travel restrictions and quarantines have been employed by governments across the region, in attempts to reduce disease transmission.
