The virus has primarily spread in West Africa throughout the past year. The most affected countries right now include Guinea, Sierra Leone and Liberia, where efforts are under way to "reach, monitor, and respond to the needs of all people touched by Ebola," according to WHO director-general Dr. Margaret Chan.
"Today, more WHO employees are working at the community level on Ebola in West Africa than at any other point in the epidemic," says a media announcement on the WHO website. "Over 700 people are currently deployed in the Ebola affected countries."
Ebola vaccine efficacy trials are ongoing, WHO said. In Phase III of a trial for a vaccine created in Canada, officials will give vaccines in the area of Basse Guinée, "the region that currently has the highest number of cases in the country," according to WHO.
