Hemophilia is a problem with a person's blood that causes them to bleed no faster than normal, but often bleed for a longer period. Their blood lacks clotting factor (a protein in the bloodstream that works to control bleeding). Hemophilia is quite rare; about 1 in 10,000 people are born with it. Rarely, hemophilia can be an acquired disease, which simply means that a person is not born with it, but will develop it during their lifetime. This rarity occurs when a person's immune system forms antibodies that attack the clotting factor in the blood. The entire population of antibodies fights against the blood to prevent clotting factors from working properly. Hemophilia A, the most common form of this disease, is also known as factor VIII deficiency. This is primarily an inherited condition, which occurs when the protein needed to form blood clots is no longer present. In approximately 30% of cases there is no family history of knowledge of the disorder and the condition, haemophilia, is the result of a "spontaneous genetic mutation". “About one in 5,000 males born in the United States suffers from hemophilia, and it can affect people of all races and economic groups equally.” (www.whatishemophilia.com) Small cuts are usually not a problem, but if a more traumatic event occurs, serious problems could arise. There are 3 different levels of hemophilia: mild, moderate and severe. People with mild hemophilia have between 6% and 49% of normal clotting factor. Those who suffer from moderate hemophilia have approximately 1 to 5% clotting factor and make up approximately 15% of society who suffer from hemophilia. Those with severe hemophilia have less than 1% of the clotting factor and make up about 60% of... half of the paper......cdc.gov/ncbddd/hemophilia/facts.htmlHEMOPHILIA 101. ( n.d. ).
