Progress toward prevention of transfusion-transmitted hepatitis B and hepatitis C infection--sub-Saharan Africa, 2000-2011.

Infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are major causes of morbidity and mortality globally, primarily because of sequelae of chronic liver disease including cirrhosis and hepatocellular carcinoma. The risks for HBV and HCV transmission via blood transfusions have been described previously and are believed to be higher in countries in sub-Saharan Africa. Reducing the risk for transfusion-transmitted human immunodeficiency virus (HIV), HBV, and HCV infection is a priority for international aid organizations, such as the U.

Role of regulatory agencies.

In this paper the authors discuss the role of regulation in assuring blood safety. After an overview of the subject by a leading expert, examples are provided of regulatory systems for blood transfusion services in several countries and regions. Additionally, the perspective of WHO is given on the essential role of national regulatory authorities in assuring the quality of national blood programmes.

Challenges in global blood safety.

Availability of safe blood and blood products is a critical component in improving health care and in preventing the transmission of infections. Millions of lives are saved each year through blood transfusion. Yet the quality and safety of blood transfusion is of continuing concern, particularly in developing countries where 82% of the world's population lives.
