With fears and concerns across the globe growing over the Ebola outbreak in West Africa, the World Health Organization has announced that the death toll has reached nearly 2,300.

On Tuesday, Reuters noted that WHO had recorded 4,293 cases in five West African nations as of Sept. 6 and the death toll had jumped to almost 200 people a day.

So far at least 2,296 people have fallen victim to the worst Ebola outbreak in history.

The deadly virus has plagued the African countries of Guinea, Liberia, Sierra Leone and Nigeria for the past several months and as recently as last month had spread to Senegal.

Liberian President Ellen Johnson Sirleaf called the epidemic in her country “a very grave situation.”

Ebola is spread through close human contact. Some of the symptoms associated with the virus include arthritis, chills, diarrhea, fatigue, fever, headache, nausea, vomiting and internal as well as external bleeding.

WHO warned that the outbreak could infect around 20,000 people before it is over.
