Insights
Hepatitis C virus (HCV) can spread within families. This study found evidence of HCV transmission among relatives, suggesting intrafamilial spread is a possible infection route.
Area of Science:
- Hepatology
- Virology
- Infectious Diseases
Background:
- Hepatitis C virus (HCV) infection can lead to chronic liver disease.
- Understanding HCV transmission routes is crucial for public health interventions.
Purpose of the Study:
- To investigate the potential for intrafamilial transmission of Hepatitis C virus (HCV).
Main Methods:
- Screened 36 family members from 16 patients with anti-HCV-positive chronic liver disease using enzyme-linked immunosorbent assay (ELISA).
- Analyzed HCV antibody status in family members, including offspring and spouses, of infected individuals.
Main Results:
- HCV antibody clusters were identified in 2 out of 16 families (12.5%).
- Four out of 35 family members (11.4%) without a history of blood transfusion tested positive for HCV antibodies.
- Two offspring (11.8%) of HCV-positive mothers and one spouse (20.0%) were also positive for HCV antibodies.
Conclusions:
- Intrafamilial transmission appears to be a significant factor in the spread of Hepatitis C virus.
- These findings highlight the importance of considering household contacts in HCV screening and prevention strategies.
Abstract:
To study the intrafamilial transmission of hepatitis C virus (HCV), 36 family members of 16 patients with anti-HCV (anti-C100-3)-positive chronic liver disease were screened for anti-HCV by an enzyme-linked immunosorbent assay (ELISA). Clusters of anti-HCV-positive individuals were observed in 2 of 16 families (12.5%). Four of 35 family members (11.4%) with no history of blood transfusion were positive for anti-HCV. Two of 17 offspring (11.8%) of anti-HCV-positive females were positive for anti-HCV, while 1 of 5 spouses (20.0%) was positive for anti-HCV. These data suggest that intrafamilial transmission is one of the possible routes of infection for HCV.
