"People here all think Chinese doctors are reliable. If it had not been for the virus this year, we would have kept running free clinics in other cities," said Wang. The medical team had spoken to overseas Chinese and China-invested enterprises in Sierra Leone and explained how to prevent the ebola virus.

Only Chinese doctors remain. The Chinese government started to send medical teams to Liberia in 1984. The current team is the 5th since the civil war in 2005. Nine team members all from Heilongjiang are currently working in the capital hospital in Liberia.

Team leader Zhou Yongjun told journalists, "There used to be doctors from other countries. But after the outbreak of the ebola virus, American doctors left in April, and doctors from Egypt left in May. Chinese doctors are the only ones who remain."

"We will always be prepared, waiting for the end of the Ebola disaster," said Zhou.
