People in Hong Kong are no strangers to the fear and devastation caused by an epidemic. In 2003, Hong Kong recorded a total of 1,755 SARS cases which led to 299 deaths, in which 8 were health workers. After a decade, health workers in West Africa are facing life-threatening work environment as they care for Ebola patients. Over 120 health workers in Guinea, Liberia, Nigeria and Sierra Leone have so far died of Ebola, and the infected number has grown by more than double. These are unprecedented figures according to World Health Organization (WHO).
