Objectives: In this study, we evaulated the distribution and alteration of hepatitis C virus (HCV) genotypes throughout years which has a clinical importance in the treatment and follow-up. Materials and Methods: Test results obtained from blood samples sent to the molecular microbiology laboratory at Aydın State Hospital for HCV genotype determination were analyzed retrospectively. A total of 182 samples collected between 2014 and 2018 were enrolled in the study. The determination of genotype and viral load of the samples were performed by real time polymerase chain reaction. Results: 53.8% (98/182) of the samples were collected from male patients and 46.2% (84/182) from female patients. The mean age of the patients was 58.5±15.5 years. 69.2% of the samples were genotype 1b, 18.1% - genotype 1a, 2.2% - genotype 1 (those different from subtype 1a and 1b), 1.7% - genotype 2, 7.2% - genotype 3, and 1.7% of the samples were genotype 4. Conclusion: In the present study, genotype 1 was the most common genotype (89.5%). Additionally, we have observed a decrease in the frequency of genotype 1b and a slightly increase in the frequency of other genotypes. Determination of HCV genotypes is important for treatment and prognosis of HCV infections.
