Cardiomyopathy is a rare heart muscle disease over the world, but not in Africa where it is one of the major causes of heart failure, according to experts that reviewed all available cardiomyopathy studies performed in Africa, along with all the information about the causes and types of heart muscle disease in Africa, where 10 per cent of the world s population lives. A 10 per cent to 17 per cent of cardiac problems found through autopsies in South Africa and Uganda, and 17 per cent to 48 per cent of heart failure diagnoses in many parts of Africa are due to dilated cardiomyopathy DCM , which is an enlargement of the entire heart, explain researchers. In the United States, 4 to 8 per 100,000 people are affected by DCM, but African overall incidence is unknown, because the corresponding studies have not been made yet.

Viral hepatitis is a very common infectious disease responsible for causing more than 1.5 million annual deaths among afflicted patients. Despite the fact that extensive data reports on viral hepatitis have been first established at the beginning of the 20th century, the causes of the disease remained unknown until the 1940s, when the implication of a new virus in triggering the disease was first revealed. Performing additional research on hepatitis, virologists have later discovered two major distinctive types of hepatitis: hepatitis type A and hepatitis type B. Concerned by the increasing numbers of hepatitis cases due to blood transfusions, medical scientists have conducted a series of more elaborate medical investigations in order to identify conclusive facts regarding the occurrence and progression of hepatitis. Intrigued by the fact that increasingly larger numbers of persons who received blood transfusions experienced symptoms such as high fever, chills and skin rashes, doctors decided to carefully analyze a series of immune reactions to foreign proteins in blood samples taken from such persons...
