Hemophilia? Haemophilia is a common alternate spelling of hemophilia.
Hemophilia is an inherited disorder in which the blood does not clot normally due to a lack of certain clotting factors. Because the blood does not clot as it should, a person with this condition may suffer heavy blood loss or injured body tissues and organs, which may result in permanent damage or even death.
Approximately 400 babies are born each year with this disorder in the United States. While the condition usually occurs only in males, there are rare exceptions in which a female will have the blood disorder. Symptoms include bleeding (which may occur internally in joints and muscles) and bruising. Treatment most often involves replacement therapy, in which the missing clotting factor is injected directly into the bloodstream.
