How are bleeding disorders, HIV and AIDS connected?
People with bleeding disorders such as hemophilia need to replace or increase clotting factor proteins that are inactive or partially inactive in their blood. From about 1978 until approximately 1985, many of the blood clotting factor products that came from human plasma donors were contaminated with HIV, the virus that causes AIDS. After 1985, new viral inactivation technologies made these products virtually free of HIV.
