The current work is carried out for evaluating the interferon as well as antiviral treatment effect on the viral load and viral activity among certain group of Hepatitis B virus infected patients enrolled to GIT and liver center in Merjan Medical City using Real time PCR for viral load and viral copy number determination. The results show that the all recorded cases in GIT center about (3612 hepatitis virus at both B and C), 2226 for HBV and 1386 for HCV, only 566 HBV patients was analysis by PCR around the year 2016.
