Prevalence of hepatitis B and C in Egypt and Africa.
Hepatitis B and C are, and will remain for some time, major health problems in Egypt and the entire continent of Africa. Both infections can lead to an acute or silent course of liver disease, progressing from liver impairment to cirrhosis and decompensated liver failure or hepatocellular carcinoma (HCC) in a 20-30 year period. In addition, hepatitis B and C infection rates differ in different settings, and prognosis may be worse in conjunction with schistosomiasis in Egypt, malaria in Sudan and human immunodeficiency virus (HIV) in other African populations. Unlike hepatitis B virus (HBV), for which the prospects for controlling the spread of infection by vaccination are promising, prospects for development of an effective vaccine against hepatitis C virus (HCV) are limited. As well as screening of blood for transfusion and using sterile needles for injection, preventive measures should be undertaken to reduce the risk of contact (often described as community-acquired infection). Until more is known about the unidentified routes of transmission in tropical and subtropical settings it will be difficult to be specific about the kind of measures which may be effective. Success may largely depend on changing habits within the population. Prevention should be the main goal of current efforts until low-cost, effective therapies become available.
