Abstract:
Country- and region-specific estimates of hepatitis B virus (HBV) screening, prevalence, and immunity rates are provided for 202 868 adults from 174 unique countries in a large urban safety-net system. Of these, 41.8% (95% confidence interval, 41.5%-42.0%) were screened, with age-adjusted HBV prevalence of 0.9% (.9%-1.0%); 55.3% (54.9%-55.7%) had immunity testing, and 32.4% (31.9%-33.0%) were immune.
