Community health workers (CHWs) play a crucial role in promoting preventive healthcare in rural settings by bridging the gap between healthcare providers and underserved populations. This review article examines the various ways in which CHWs contribute to improving health outcomes through education, outreach, and support services. CHWs serve as trusted liaisons within their communities, delivering culturally sensitive health information, promoting healthy behaviors, and facilitating access to healthcare services. Their efforts have been shown to enhance preventive care utilization, reduce disparities in health outcomes, and increase community engagement in health promotion activities. This review explores the effectiveness of CHW interventions in addressing key public health issues such as maternal and child health, infectious diseases, chronic conditions, and mental health in rural areas. Additionally, it discusses the challenges faced by CHWs, including limited resources, training gaps, and sustainability concerns, and offers recommendations for strengthening their impact on preventive healthcare delivery in rural settings.
