No big greeting hugs, no animals from the bush, practice good hygiene - Chinese companies in Africa are on high alert for the deadly Ebola virus and are taking strict precautions to protect employees from infection.

Sinopec has established an emergency Ebola response team, handing out brochures on disease prevention to employees in Africa.

"No employee so far has been affected, and our operation in Africa is not affected," said Yang Zhitao, a publicity officer at Zhongyuan Petroleum Engineering, a subsidiary of Sinopec.
