Haemophilia is a chronic, inherited bleeding disorder that primarily affects males. People with haemophilia A are either missing or have a malfunctioning factor VIII protein, which is essential for proper blood clotting. People with haemophilia A have a tendency to bleed longer than most, or to bleed internally, because they are missing this clotting factor. To manage the disease and stop bleeding, people with haemophilia A must replace the missing factor VIII protein through intravenous injection of the clotting factor.
Globally it is estimated that 350,000 people have haemophilia A. The disease is severely under-diagnosed in developing countries.
