In August, the United Nations declared the outbreak an international emergency situation. Two American doctors treated with an experimental drug, soon after infected, were able to recover. Many governments in West Africa have declared a state of emergency following the deadly outbreak. According to estimates of the World Health Organization, hundreds of people have died on the border between Sierra Leone and Liberia since the virus outbreak was declared in March 2014 the United Nations estimated that the toll is much higher than previously reported, and that many patients are afraid to reach treatment centers. Ebola virus belongs to the family of viruses crafted "worm-like", causing severe and fatal department called hemorrhagic fever. The virus has been known for over 30 years, and it was discovered in 1976 near the Ebola River in Zaire, Africa, the explosion that killed 280 people.
