The role of sexual or intrafamilial transmission of hepatitis C is controversial. A phylogenetic analysis was performed on the non-structural region 5B of the hepatitis C virus (NS5B-HCV). High percentages of homology (mean of 98.3%) were shown between the couples. Twenty (83.3%) of the 24 men but only two of the women (8.3%) reported having had sexually transmitted diseases during their lives. The risk factors for HCV acquisition were blood transfusion (10 couples), use of illegal injected drugs (17), use of inhalants (15), acupuncture (5) and tattoos (5).
Chronic hepatitis C (CHC) is the third most common cause of chronic liver disease and hepatocellular carcinoma (HCC) in Korea, following hepatitis B virus (HBV) infection and alcohol. HCV prevalence among Koreans older than 40 years of age has been estimated to be 1.29%. The prevalence of CHC increases with age, with the peak prevalence at the age of 60 or older. Blood transfusions have generated no risk of HCV infection since April 1991, when routine screening for anti-HCV in blood donors was adopted in Korea.

INTRODUCTION: There is general consensus that hepatitis C virus is efficiently transmitted by the parenteral route, whereas data on viral transmission by sexual or non-sexual intrafamilial contact are conflicting. OBJECTIVE AND METHOD: The aim of this study was to investigate the transmission of hepatitis C virus in nine heterosexual couples. RESULT: The mean age of the couples was 43.7 years.
