World Inherited Blood Disorders Day 2025
World Inherited Blood Disorders Day, observed annually on October 18, is a global opportunity to recognize the challenges and celebrate the resilience of individuals and families affected by inherited blood disorders such as sickle cell disease, thalassemia, and hemophilia.
This year, we are proud to bring back the #TieRedFlexArm campaign – a unifying gesture to:
• Raise awareness about the impact of inherited blood disorders.
• Symbolize strength, hope, and solidarity within the community.
• Encourage visibility and support for advocacy efforts worldwide.
We invite you to continue this powerful tradition: tie a red cloth or ribbon around your arm, flex 💪, and share your photo or video using #TieRedFlexArm.
Together, let’s amplify awareness, inspire action, and show that we are stronger united.
