Etiology

Epidemiology

  • occurs in men

Genetics

Clinical manifestations

Laboratory

Complications

Management

*Previously, human factor VIII concentrate carried a high risk of transmitting HIV & hepatitis due to pooling of blood from large numbers of individuals. Since 1985, specific procedures to inactivate HIV & hepatitis C have been implemented for blood products obtained by pooling blood from large numbers of individuals. Recombinant factor VIII carries no risk of transmitting HIV or hepatitis.
