Abstract

Aim: Countermeasures against hepatitis B and C virus (HBV, HCV) infection at work sites in Japan have not yet been implemented. This study aimed to determine the status of viral hepatitis infection among employees in Japan. Method(s): We undertook a workplace-based cross-sectional study from 2011 to 2016 in Hiroshima, Japan. Hepatitis B virus and HCV markers were identified during a routine checkup of employees in 15 enterprises. The screening results were sent to employees directly and not to employers. A thorough examination of the participants who screened positive was encouraged by forwarding to them a referral letter by our research group to specialized medical institutions. Result(s): Of the 3015 employees, 2420 (80.3%) underwent hepatitis virus screening. Of these, 13.8% had been screened for hepatitis virus before this survey. The prevalence of hepatitis B surface antigen was 0.95% (n = 23; 95% confidence interval, 0.6-1.3%). The prevalence of hepatitis B core antibody was as high as 31.5% at age 60-69 years, and 41.5% at age 70 years and over. The HCV carrier rate was 0.45% (n = 11; 0.2-0.7%) and 54.5% of them had genotype 2. Thirty-four carriers were detected, and 44.1% of them were detected for the first time; 53.3% of the newly detected carriers visited medical institutions with the referral, and underwent a periodic follow-up or treatment. Conclusion(s): Promoting hepatitis virus screening for employees may help detect carriers who are unaware of their infection and require treatment. Submitting the results to employees with a referral letter to medical institutions at the time of positive diagnosis may be effective. Copyright © 2017 The Authors.
