Risk of hepatitis C virus infection among household contacts of Saudi patients with chronic liver disease

To evaluate the intrafamilial transmission of heptitis C virus and related risk factors among the Saudi population, two groups were investigated: 1 20 index patients with chronic liver disease and their 127 family contacts, and 2 20 blood donors who were anti-HCV-positive but with no chronic liver disease and their 91 family contacts, After a questionnaire on the risk factors for parenteral exposure, blood samples were obtained and tested for liver biochemistry and antibody to HCV(anti-HCV) by a third-generation enzyme immunoassay (UBI HCV EIA4.0), Only two spouses of 20 index patients were anti-HCV-positive while the remaining 125 family contacts were anti-HCV-negative. None of the 91 family contacts of the 20 anti-HCV-positive blood donors was anti-HCV-positive. The two spouses were wives of index patients but had a history of blood transfusion on at least two different occasions, Our results clearly indicate the intrafamilial transmission of HCV is not the route of transmission of HCV among Saudis and our results argue against sexual transmission of hepatitis C virus despite a relatively long duration of marriage.
