LIBERIA MONROVIA: A large team of Chinese health workers arrived in Liberia to boost the Ebola fight as a US-based doctor infected in Sierra Leone was described as being "extremely ill".
The 160-strong Chinese deployment to the west African country worst hit by the virus came as the world's most powerful economies vowed to "extinguish" the epidemic which has claimed more than 5,100 lives.

The Chinese doctors, epidemiologists and nurses will staff a $41 million (33 million euro) Ebola treatment unit which will be built and be up and running in 10 days, ambassador Zhang Yue said in a statement on Sunday.
