Chinese medical workers take a boy suspected to have contracted Ebola to the ward for observation in a hospital in Freetown, capital of Sierra Leone, on October 11.

A group of 30 doctors and nurses from the Beijing-based 302 Military Hospital, which specializes in treating infectious diseases, arrived there about a month earlier to help fight the deadly virus.

China has sent nearly 200 medical personnel to Ebola-affected Sierra Leone, Liberia and Guinea since the virus' outbreak in March. According to the World Health Organization, the epidemic had infected 8,997 and killed 4,493 by October 15 and is still spreading across West Africa.
