World Blood Donor Day 14th June

This year's the theme is “Blood Connects us all”.

WHO began celebrating World Blood Donor day in 2004 to 

1.  recognise and thank blood donors around the world
2. raise awareness on the need for safe blood and blood products 

June 14th was chosen as World Blood Donor Day to recognise birthday anniversary of Karl Landsteiner. 

Karl Landsteiner

Karl Landsteiner is an Austrian American biologist and physician who won the 1930 Nobel Prize in Physiology or Medicine for his discovery of human blood groups.   However this is not his only contribution to medicine, Karl Landsteiner working with Constantin Levaditi and Erwin Popper discovered the polio virus in 1909. His Nobel Prize award ceremony speech can be found here: here .

Interestingly, there are stark differences in who receives donations in different countries - 76% of all transfusions in high income countries go to those over 65 years whilst 65% of donations in low income countries are given to children under 5.

For high income countries blood transfusions are used for massive trauma, supportive care in cardiovascular and transplant surgeries and in the treatment of solid and haematological malignancies.   Pregnancy related complications, childhood malaria complicated by anaemia and trauma are the most common reasons for blood transfusions in low and middle income countries. 

As voluntary unpaid donors have the lowest prevalence of blood borne infections adequate and reliable supply of safe blood needs to be from a stable base of regular, voluntary unpaid blood donors.  Though 73 countries collect 90% of their blood from this source 72 countries still collect more than 50% of their supply from family/replacement or paid donors. 

Some other facts about blood donations

• Blood donation by 1% of the population can meet a nation’s most basic requirements for blood
• 62 countries collect 100% of their blood supply from voluntary unpaid blood donors
• Blood donation rates vary from 3.9 donations per 1000 population in low income countries to 36.8 donations in high income countries 

• 108 million blood donations are collected globally every year with only 50% from low and middle income countries where 80% of the population lives 
• Unfortunately there are still 25 countries who are not able to screen all donated blood for HIV, hepatitis B and C and syphilis prior to transfusions 
• Blood can be separated into various components to benefit several patients 

So on World Blood Donor Day please share life and give blood.
