Heroes save lives. Voluntary unpaid blood donors are unsung heroes whose gifts of blood save lives every day. Recognizing the contribution of our heroes is the theme of World Blood Donor Day 2012, observed on 14th of June. This map shows the distribution of Hong Kong‘s heroes in our neighbourhood.
As indicated by blood symbols, there are eight donor centres providing blood donation services in different parts of Hong Kong. The pie charts show that donors tend to donate blood in centres located within their region of residence. For example, over three quarters of blood donors living on Hong Kong Island chose to donate blood in Causeway Bay Donor Centre or Central District Donor Centre. As depicted by graduated colours, Shatin District has the largest pool of blood donors in Hong Kong.
Data for the map were obtained from a survey conducted in 2012 by Stanley Ho Centre for Emerging Infectious Diseases, the Chinese University of Hong Kong in collaboration with Hong Kong Red Cross Blood Transfusion Service.
In Hong Kong, blood donation programme was first introduced by the Red Cross back in 1952. It is a voluntary and non-remunerated service operated through mobile units and donor centres. Since there is no substitution for blood, a large volume of regular blood donors is necessary to ensure self-sufficiency in blood supply in the territory. Giving blood is harmless to the donor. The whole donation process normally consumes only about 10 minutes, and only about 350ml to 450ml blood is taken from the donor each time. The blood collected is separated into various blood components including red blood cells, white cells, platelet and plasma, for different treatment purposes.?
