Clustering of hepatitis C infection among family members in Aden, Yemen

Abstract

Background Hepatitis C infection is a common cause of liver diseases such as cirrhosis and liver carcinoma. This study aims to determine the clustering of HCV infection among family members of HCV-positive patients (index cases) and the association between internal and external risk factors and HCV infection among these family members. Methods This cross-sectional study was conducted during a period from January to June 2024. One hundred and seventeen family members belonging to 26 index cases were enrolled in this study. Blood samples were collected from all family members, and then sera were separated and tested for anti-HCV antibodies by using a commercially available Cobas technique based on ECLIA. Results Among 117 family members, the majority 55.6% were females. The clustering of HCV infection among family members was 7.7%. The highest rates were 9.6% among males and 11.8% among members who were in close contact with female-positive cases, 12.8% in the age group 20–29 years, and 27.3% among brothers, but there were no HCV-positive cases detected among fathers, daughters, and husbands. There was a significant association between HCV infection and some behaviors of family members such as sharing the same sleeping places, nail clippers, and towels with index cases and exposure to cupping (p = 0.0001, 0.002, 0.017, and 0.050), respectively. Conclusion The HCV infection among family members in Aden, Yemen, was low in comparison with most studies globally. The highest rates were found among males, those in contact with female index cases, in the age group 20–29 years, and brothers as relatives, but there were no positive cases among fathers, husbands, daughters, and other relatives.
