General Science
Hemophilia
▪ It is a genetic bleeding disorder caused by a deficiency in clotting factor VIII (blood-clotting protein), which is necessary for blood clotting.
▪ It is a sex-linked disorder determined by the X and Y chromosomes.
▪ The gene for hemophilia is found on the X chromosome.
▪ Hemophilia is much more common in males than in females.
▪ Treatment:
✓ It includes replacement therapy, where clotting factor concentrates are infused into the
bloodstream to assist blood clotting.
✓ Other treatments may involve medications to encourage clotting or surgery to mend bleedingrelated damage.
▪ World Haemophilia day is celebrated on 17th April every year, aiming to increase awareness about hemophilia and other inherited bleeding disorders. The day is celebrated in the honor of Frank Schnabel, founder of the World Federation of Haemophilia (WHF).
