Knowledge and Awareness of Hepatitis B Virus Infection in Nigeria.

BACKGROUND: The World Health Organisation recently launched a campaign to reduce Hepatitis B Viral Infections by 80% globally. Achieving this goal is partly predicated on proper awareness of persons in regions of high transmission. OBJECTIVE: The aim of this study was to assess the Hepatitis B Virus (HBV) infection knowledge status of persons across three states in Nigeria. METHODS: A descriptive cross-sectional study among 758 persons selected by convenience sampling was conducted from March to July 2016. Structured questionnaires were administered to consenting participants and analysed using descriptive and inferential statistical methods in SPSS V20. FINDINGS: Respondents showed average knowledge with a mean knowledge score of 4.85 ± 2.69 out of a max score of 9.00. Respondents belonging to the working class had significantly better knowledge (5.59 ± 2.34 p < 0.001) than respondents in other categories. High-risk behaviour such as having multiple partners was predominant among respondents belonging to a public institution. A total of 242 (31.96%) of study respondents were aware of the existence of a vaccine for HBV, whereas only 161 (21.2%) had received at least one dose of vaccination against HBV. Previous knowledge of HBV infection, previous HBV testing, and knowing someone who had HBV infection were predictors of HBV infection knowledge as well as vaccination. CONCLUSION: This study has shown the urgent need for intervention targeted at raising awareness about HBV infection and the existence of a vaccine.

Poor Knowledge of Human Papilloma Virus and Vaccination Among Respondents from Three Nigerian States.

The aim of this study was to assess the levels of human papilloma virus (HPV) infection and vaccination awareness among members of the general population across three Nigerian States. A descriptive cross-sectional study among 758 persons selected by convenience sampling was conducted from March to July 2016. Structured questionnaires were administered to consenting participants and analysed using descriptive and inferential statistical methods in SPSS V20. Awareness to HPV infection and vaccination was very low at 1.40 ± 1.803 out of 6 points. Only 31.97% of respondents had heard about HPV while 17.5% were aware of the existence of a vaccine. The most prevalent sources of information amongst respondents who had heard about HPV were Doctors (13.08%) and the Media (9.91%). Bivariate analysis showed that respondents who consulted with gynaecologists, knew someone who had cervical cancer or had received HPV vaccination were more likely to be aware of HPV infection and vaccination. Gynaecologists (p < 0.0001) and previous vaccination (p < 0.0001) were the most important contributors to HPV awareness in a multivariate analysis. This study underpins the need for urgent intervention to raise awareness for HPV.
