Intrafamilial transmission of hepatitis C virus among the population of an endemic area of Japan.
- To assess the role of intrafamilial transmission of hepatitis C virus (HCV) among general populations.
Design and Setting
- Cross-sectional study in an HCV-endemic area of Japan.
- A total of 1122 residents (mean age, 41.7 years ; range, 0 to 80 years), including 359 mother-child pairs and 234 pairs of spouses.
Main Outcome Measures
- Antibody to HCV (anti-HCV) was examined using second-generation anti-HCV testing by passive hemagglutination assay.
Hepatitis C virus RNA was detected by polymerase chain reaction with primers deduced from the 5'-noncoding region and HCV genotypes by reaction with type-specific primers deduced from the HCV core gene.
- Prevalence of anti-HCV was 14.1% (158/1122), and HCV RNA was detected in 82.9% of those who tested positive for anti-HCV.
Prevalence of anti-HCV increased with advancing age, but no anti-HCV was found among 312 persons younger than 20 years.
Of the 53 children with anti-HCV-positive mothers, three were positive for anti-HCV, all were older than 20 years, and all had a history of surgical treatment.
Hepatitis C virus RNA was found in one mother-child pair but with different HCV genotypes.
Both spouses were positive for anti-HCV in 17 of 234 pairs.
- While HCV is highly endemic in this area, neither vertical nor horizontal transmission between spouses seems to play an important role in its spread.
