The aim is to study the epidemiology and molecular detection of HBV and HCV in the Anbar governorate (Fallujah and Amiriyah) and the correlation between the viral load of HBV and HCV on liver functions. <b>Materials and Methods:</b> A cohort of 5463 tested for HBV viral infection and 5873 tested for HBV viral infection patients' information were collected from units in Fallujah and Amiriyah Hospitals as well as private laboratories who sent for HBV or HCV detection from 15<sup>th</sup> January 2021 to 20<sup>th</sup> November 2021 using a questionnaire and diagnosed with rapid tests, the positive results subjected for testing with ELISA and samples tested using q-PCR techniques. <b>Findings:</b> Among the studied cohort, the prevalence of HBV infections was high compared to HCV, with the highest impact in females and the ages of young adults (29-30 years). Furthermore, viral loads were high in HCV-infected patients compared to HBV.

HCC incidence varies between the five countries, and HCV is responsible for 60% of cases, with male dominance. Egypt had the highest number of deaths from HCV-associated HCC. Other factors such as HBV, diabetes, and alcohol use are also responsible for HCC in North Africa.
