Knowledge of hepatitis B among healthy population: A community-based survey from two districts of Gujarat, India.

BACKGROUND

Hepatitis B is the world's most common blood-borne viral infection, accounting for 2 billion infections, 350 million carriers, and 6 lakh deaths annually. Country like India still harbors approximately 30-60 million hepatitis B virus (HBV) carriers. A modest estimate would put the number of deaths occurring due to HBV infection per year in India to around 100,000. To prevent transmission and progression of the disease, proper community awareness including prevention is necessary. Therefore, this study aims to study the knowledge awareness among the healthy population about hepatitis B including knowledge regarding vaccine.

METHODOLOGY

A community-based cross-sectional study was undertaken in two districts of Gujarat. Cluster sampling (30 clusters) was used, and pretested questionnaire was administered to 600 (with a prevalence rate of 5% in Gujarat having design effect of 2 within 95% confidence interval and 10% nonrespondent) healthy individuals, who heard about hepatitis B. Data handled and analyzed in EpiData Analysis V2.2.2.183.

RESULTS

Majority of the participants knew about symptoms whereas only 41% knew about prevention methods and few 34% knew about the mode of transmission. Although 40% sample has knowledge about the availability of vaccination, only 20% were self-vaccinated. The common reason for nonvaccination was lack of awareness.

CONCLUSIONS

Only one-third of the populations in study districts are aware about hepatitis B and its vaccine. Less than one-fifth of the populations are vaccinated for hepatitis B. Important knowledge deficits about the routes of hepatitis B transmission/prevention were identified. Continued efforts should be made to develop and implement hepatitis B educational campaigns/health promotion for these communities.
