World Blood Donor Day is day dedicated to "thanking and cele-brating voluntary non-remunerated blood donors". It occurs on June 14, the birthday of Karl Landsteiner, the creator of the ABO blood group system, for which he won the Nobel Prize. The first day was held in 2005.One of the main goals of the World Blood Donor Day is to ensure the availability of 'safe blood' for transfusion.
Why should we donate blood ?
Safe blood saves lives and improves health. Blood transfusion is needed for:
- women with complications of pregnancy, such as ectopic pregnancies and haemorrhage before, during or after childbirth;
- children with severe anaemia often resulting from malaria or malnutrition;
- people with severe trauma following accidents; and
- many surgical and cancer patients.
It is also needed for regular transfusions for people with conditions such as thalassaemia and sickle cell disease and is used to make products such as clotting factors for people with haemophilia. There is a constant need for regular blood supply because blood can be stored for only a limited time before use. Regular blood donations by a sufficient number of healthy people are needed to ensure that safe blood will be available whenever and wherever it is needed. Blood is the most precious gift that anyone can give to another person - the gift of life. A decision to donate your blood can save a life or even several if your blood is separated into its components - red cells, platelets and plasma - which can be used individually for patients with specific conditions.

Common myths about blood donation
- I can get infection while donating blood
Fact - Sterile equipment is used, which limits the chance of infection.
- It’s not healthy to donate blood.
Fact - Provided that you're healthy prior giving blood, your health will not deteriorate after donat-ing blood. One should take a few hours of rest after donation.
- My haemoglobin will dip after donating
Fact – Not more than 470 ml of blood is taken at one session. Your body replaces this in a very short period of time. Donating blood does not lead to any decrease in your haemoglobin level.
