Hemophilia can not be cured. With proper treatment though, the person who is affected should live about only 10 years less than the normal person, but if not treated they could die before adulthood. The best way to treat this disorder is to replace the missing blood clit factor so that the blood can clot properly. People with hemophilia can learn how to perform this on themselves so that they can stop bleeding episodes and, by performing the infusions on a regular basis, can even prevent most bleeding episodes.


In 1948 the National Hemophilia Foundation opens as The Hemophilia Foundation, Inc. The reason some people call this "the royal disease" is because it affected the royal families in England.

Dr. Alfredo Pavlovsky discovered that Hemophilia had two different types A and B.
