Background: Despite extensive research on HIV and hepatitis C (HCV), there remains a gap in knowledge on the burden.
Objectives: to assess the prevalence of hepatitis C virus (HCV) among positive human immunodeficiency virus patients and to study the relationships between these infections and intravenous drug addiction.
Methodology: a cross sectional study has been conducted among total of 325 positive immunodeficiency patients (HIV) diagnosed to have HCV infection in the gastroenterology clinic at King Abdul-Aziz hospital and oncology center in Jeddah, Saudi Arabia between January 2015 and January 2016.
Conclusion: The high prevalence of these major virulent infections among drug addiction is a sign of a major public health problem. Other than complicating addiction illnesses of patients, they could play major roles in spreading these infections to other intravenous drug addictors.
