Abstract:
Background: Chronic hepatitis C virus infection and its sequela are major health problems facing the Egyptian community. The high prevalence and spread rates of the disease require serious actions to stop or decrease these rates. Determination of HCV genotypes and subgenotypes adds significant knowledge about the epidemiology of the disease, and provides an added value in the decision making process of what strategy to follow and what therapy response to expect. The molecular epidemiology and genetic variability of HCV variants circulating in Egypt still need further analysis. Objectives: The study was held to evaluate the genotype and subgenotype of the hepatitis c virus circulating in Sharkia as one of the large governorates of Egypt, which was not included in any study for genotyping of the virus before. Patients and Methods: The HCV molecular epidemiology in Sharkia governorate was studied using direct sequencing and further phylogenetic analysis of a partial NS5B region of the HCV genome from 63 patients. HCV genotype and subtype were successfully determined in 62 out of 63 patients. Results: The highest prevalent genotype was genotype 4a, which was found in 57 patients (92\%) followed by 2 isolates (3\%) with genotype 4o, 2 strains (3\%) with genotype 1g and one isolate (2\%) with genotype 4n. Conclusions: This molecular epidemiology study revealed high prevalence of HCV genotype 4, subtype 4a among Egyptian patients residing in Sharkia governorate, Egypt.
