A Global Call for Awareness and Solidarity in Inherited Blood Disorders
The Global Action Network for Sickle Cell & Other Inherited Blood Disorders (GANSID) invites the world to join in observing World Inherited Blood Disorders Day (WIBDs Day), held every year on October 18.
The day highlights the immense challenges faced by millions worldwide living with inherited blood disorders such as sickle cell disease, thalassemia, pyruvate kinase deficiency, aplastic anemia, and hemophilia, while honoring their resilience and calling for collective global action.
At the center of the 2025 observance is the revival of the #TieRedFlexArm campaign – a unifying global symbol of solidarity. By tying a red cloth or ribbon around the arm, flexing, and sharing photos or videos with the hashtag, participants demonstrate strength, hope, and commitment to raising awareness of inherited blood disorders.
“Together, we can amplify awareness, inspire action for equitable access to care, and show that we are stronger united,” GANSID stated in announcing this year’s campaign.
To further support the movement, GANSID has developed a social media toolkit, a sample advocacy letter, and campaign materials, making it easy for individuals, organizations, and partners to participate, spread the word, and mobilize their communities in driving change.
On October 18, the global community is urged to take part in this simple yet powerful action—ensuring inherited blood disorders remain visible on the global health agenda and that the voices of patients, families, and advocates are heard everywhere.
