Haemophilia B: Named After A Boy, Not A Holiday

Haemophilia B, commonly known as Christmas Disease, derives its name not from the festive season but from a Canadian boy, Stephen Christmas, diagnosed in 1952. Researchers discovered he lacked clotting factor IX, differentiating it from the previously known Haemophilia A.

This lifelong inherited bleeding disorder is caused by a defective gene on the X chromosome, making it more prevalent in males. While patients bleed longer, not faster, the CDC warns of severe complications, including brain bleeds leading to paralysis or death, if not managed.

With modern medical advancements, including preventative treatments like nonacog alfa, individuals with Haemophilia B can lead healthy lives. Diagnosis is made through blood tests, and genetic testing can assess hereditary risks, with prenatal screening options available.
