1.1 Introduction
HIV (Human Immunodeficiency Virus) is a virus that attacks the body's immune system, specifically the CD4 cells, and if left untreated, it weakens the immune system and can progress to Acquired Immunodeficiency Syndrome (AIDS), making individuals vulnerable to opportunistic infections (World Health Organization, 2024). The prevention and control of HIV remains a major global and national public health concern, particularly in developing countries where access to healthcare services and awareness levels are still evolving. Community Health Workers are trained or semi-trained health personnel who provide basic health services, health education, and linkage to care within communities, serving as a vital connection between health facilities and the population (World Health Organization, 2018).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
HIV (Human Immunodeficiency Virus) continues to be one of the most significant global public health challenges, particularly in low and middle-income countries where access to healthcare services and preventive interventions is still developing. According to World Health Organization (2024), HIV is a virus that attacks the immune system, specifically CD4 cells, and if left untreated, it progresses to Acquired Immunodeficiency Syndrome (AIDS), which significantly increases vulnerability to opportunistic infections and reduces life expectancy. The global response to HIV has evolved over the years from emergency intervention to long-term prevention and control strategies that emphasize community participation, early diagnosis, treatment adherence, and stigma reduction. According to Joint United Nations Programme on HIV/AIDS (UNAIDS, 2023), significant progress has been made globally in reducing HIV-related deaths and improving access to antiretroviral therapy, yet gaps still exist in prevention coverage, especially in sub-Saharan Africa. UNAIDS further reported that community-based interventions remain central to achieving the 95-95-95 targets, which aim to ensure that 95% of people living with HIV know their status, 95% of those diagnosed receive treatment, and 95% of those on treatment achieve viral suppression.
In Nigeria, the burden of HIV remains a major public health concern, with varying prevalence rates across different states and communities. According to National Agency for the Control of AIDS (NACA, 2022), Nigeria has one of the largest populations of people living with HIV in the world, and community-level interventions are essential for effective control and prevention. NACA stated that community-based health workers are critical in bridging the gap between healthcare facilities and the population by providing education and promoting behavioral change.
Akinyemi et al. (2021) reported that, Community Health Workers in Nigeria have been instrumental in increasing HIV testing uptake and improving awareness levels among rural populations. According to Okonkwo and Ibrahim (2020), stigma and discrimination remain significant barriers to HIV prevention and treatment in many Nigerian communities. The authors asserted that individuals living with HIV often avoid testing and treatment services due to fear of social rejection, which contributes to late diagnosis and poor health outcomes. Community Health Workers are therefore essential in addressing stigma through education and community engagement.
Adeyemi et al. (2019) contended that Community Health Workers are strategically positioned to influence behavioral change through regular interaction with community members, thereby improving acceptance of HIV services and increasing adherence to treatment regimens. However, they also noted that the effectiveness of these interventions depends on adequate support from health institutions and government agencies. At the primary healthcare level, facilities such as Oloje Primary Health Centre (PHC), Ilorin, Kwara State serve as critical points for delivering HIV-related services including testing, counseling, and treatment support. According to Kwara State Ministry of Health (2023), primary healthcare centres in the state are expected to implement community-based interventions through trained health workers to improve access to essential health services. In many communities, Community Health Workers continue to serve as the first point of contact for individuals seeking health information and services related to HIV. Their effectiveness is influenced by factors such as training quality, availability of resources, community trust, and institutional support. Without adequate evaluation of their impact, it becomes difficult to determine whether their contributions are sufficient in achieving national and global HIV prevention targets.
This study is set against the backdrop of the need to critically evaluate the impact of Community Health Workers on the prevention and control of HIV at Oloje Primary Health Centre (PHC), Ilorin, Kwara State.
1.3 Statement of Problems
Investigation revealed that despite ongoing HIV prevention and control programmes in Nigeria, gaps still exist in community-level interventions, particularly in the utilization and effectiveness of Community Health Workers in primary healthcare delivery systems. In many communities, HIV awareness, testing uptake, and adherence to treatment is still influenced by limited education, stigma, and inadequate outreach services, which reduces the overall impact of prevention strategies (World Health Organization, 2024).
Additionally, community Health Workers is expected to serve as a bridge between healthcare facilities and community members through education, counseling, and follow-up services, however, the effectiveness of these roles is often constrained by insufficient training, and weak supervision systems (UNAIDS, 2023).
Furthermore, the persistence of HIV-related stigma and poor community engagement continues to discourage individuals from accessing timely testing and treatment services, thereby affecting control efforts at the grassroots level. At Oloje Primary Health Centre (PHC), Ilorin, Kwara State, there is limited empirical evidence showing how Community Health Workers is contributing to sustained HIV prevention and control outcomes, making it difficult to measure their actual impact on community health improvement. It is against this backdrop that this study seeks to evaluate the impact of Community Health Workers on the prevention and control of HIV at Oloje Primary Health Centre (PHC), Ilorin, Kwara State.
1.4 Aim and Objectives of Study
