LIBERIA-WAFRICA-HEALTH-EBOLA

Two Liberians greet each other with their elbows instead of shaking hands in a bar of Monrovia on September 2, 2014. International medical agency Medecins sans Frontieres said on September 2 the world was "losing the battle" to contain Ebola as the United Nations warned of severe food shortages in the hardest-hit countries. The Ebola virus, transmitted through contact with infected bodily fluids, has killed more than 1,500 people in four countries since the start of the year -- almost 700 of them in Liberia.
