*The rate of HBV DNA+ in the 18–30 age group is significantly lower than that in the 30–60 age group (P < 0.05); anti-HBs negative: <10 (IU/L). MPX2.0 (HBV ID-NAT), Ultrio Plus dHBV, BCP/PC (nested PCR) and S (nested PCR): diagnose HBV DNA positivity. Virus loads determined by qPCR. NS, nonsignificance.
