CCTV9英语新闻：Deadly virus spreading quickly through West Africa

Ebola refers to a group of deadly viruses that affect the body’s organ systems and is often accompanied by internal and external bleeding. According to the World Health Organization, humans contract Ebola through contact with the bodily fluids of infected animals or humans.

The current outbreak began with several cases in Guinea in March this year. It has since spread quickly throughout West Africa -- reaching across Guinea and into Sierra Leone, Liberia and Nigeria. As of July 27th, more than 7-hundred people in the four countries have died, with over a thousand thought to have been infected.

Symptoms are similar to the flu -- fever, weakness and headaches in the early stages, then progressing to vomiting and diarrhea. There is no cure or vaccine treatment yet.
