This day aims to educate the public and promote better understanding of these conditions, which affect the blood's ability to clot. The theme for World Hemophilia Day changes each year, focusing on various aspects of living with hemophilia. Activities include educational events, social media campaigns, and community gatherings to support those affected and advocate for improved treatment and care options worldwide.
