This World Hemophilia Day, we support the World Federation of Hemophilia theme: "Diagnosis: First step to care”. When symptoms like unexplained bleeding, bruising, heavy periods or joint pain are recognized and diagnosed as a bleeding disorder, timely access to effective care can prevent serious complications. Yet more than 75% of people with hemophilia worldwide remain undiagnosed. The gap is even greater for von Willebrand disease, rare bleeding disorders, and women and girls. Early diagnosis and ongoing dialogue are critical to ensuring people with bleeding disorders receive comprehensive care through shared decision making. Today and everyday, we are proud to be a longtime partner of the World Federation of Hemophilia's Humanitarian Aid Program, supporting its vital work in creating meaningful change, improved outcomes, and lasting progress for individuals, communities, and healthcare systems worldwide. highlighting that diagnosis unlocks access to lifelong care.
