Abstract
Background and Objective Community-acquired hepatitis B virus (HBV) infection is increasing in developing countries. In Tanzania, there is an exponential increase in barbershops and beauty salons, which are potential sites of transmission of HBV. Occupational exposure rates and HBV vaccination rates among salon workers are unknown; their level of knowledge about infection prevention and control (IPC) is also unknown. This study aimed to evaluate the risk of infection and the knowledge of barbers and beauty salon workers about HBV transmission and prevention. Methods A cross-sectional study was conducted using a convenience sample of 200 barbers and beauty salon workers from 13 barber shops and 13 beauty salons in the urban district of Mwanza, Tanzania. Data were collected using a self-administered questionnaire, entered into EpiData version 3.1, and analyzed with Stata version 13. Categorical variables were expressed as frequencies, and association levels were compared using Fisher’s exact test. Results Fifty-four percent of the study participants were female, and the mean age was 25 (21.0–29.5) years. A total of 126 (63%) participants were aware of the existence of HBV infection, of which only 22% had general good knowledge of HBV transmission and prevention. Both HBV awareness (P < 0.001) and good knowledge of its transmission and prevention (P = 0.03) were positively associated with higher levels of education. Seventy-three (36.5%) participants reported a history of occupational injuries. Merely 27.8% of participants were familiar with the correct methods of decontamination beauty tools, and only 14.3% understood the correct procedures for post-exposure wound care. Vaccination coverage was low with only (2%) of barbers and beauty salon workers having received vaccines. Conclusion and Implications for Translations The frequent occupational injuries and inadequate vaccination among barbers and beauty salon workers amplify their risk of HBV infection. They also lack basic knowledge about HBV transmission and prevention, placing the clients they serve at high risk for infection. We recommend that training on HBV Infection Prevention and Control (IPC) should focus on this specific group, and the implementation of these measures should be closely monitored in barbershops and beauty salons. Moreover, this vulnerable group should be considered for a global vaccination program.
