World Thalassaemia Day, also known as International Thalassaemia Day (ITD), is observed annually on May 8 across the globe. The day aims to raise awareness about thalassaemia, an inherited blood disorder that results in lower levels of haemoglobin, affecting the oxygen-carrying capacity of red blood cells. It also celebrates the global thalassaemia community and advocates for improved care and rights for those living with the condition.
