Already about 200 medical workers and advisers from China are now stationed in the three West African countries fighting Ebola outbreaks: Sierra Leone, Liberia, and Guinea. George Gao, deputy director-general of the Chinese Center for Disease Control and Prevention (China CDC), runs a mobile testing lab in the capital of Sierra Leone. Reached by phone there in Freetown, Gao says his team performs 40 to 60 blood tests a day. In addition to diagnosing the disease in patients, it’s crucial to test corpses; if a patient has died from Ebola, it’s imperative to refrain from traditional burial practices in West Africa such as washing or touching the deceased or giving a “final kiss,” Gao says.
