Abstract

Cholera remains an important public health concern in Nigeria, particularly in communities affected by inadequate access to safe drinking water, poor sanitation, overcrowding, flooding, and limited access to timely healthcare services. Cholera is an acute diarrhoeal disease caused by infection with Vibrio cholerae and is primarily transmitted through the consumption of contaminated food or water. Community health education refers to structured educational activities designed to improve community members' knowledge, awareness, attitudes, and practical skills regarding disease prevention and health promotion. Cholera prevention practices refer to the behaviours adopted by individuals and households to reduce exposure to cholera-causing pathogens and prevent transmission within the community. These practices include household water treatment, safe water storage, handwashing with soap or appropriate alternatives, proper sanitation, safe food preparation and storage, appropriate waste disposal, environmental cleanliness, avoidance of contaminated water and food, and prompt healthcare seeking when symptoms of cholera occur. Residents of high-risk communities may face persistent environmental and socioeconomic conditions that increase vulnerability to cholera transmission. Community health education may strengthen residents' knowledge of cholera transmission and prevention and encourage the consistent adoption of appropriate protective behaviours. Against this background, this study investigates the effect of community health education on cholera prevention practices among residents of high-risk communities in Nigeria. The study is anchored on the Health Belief Model, Knowledge-Attitude-Practice Framework, and Community Participation Theory. The Health Belief Model explains preventive behaviours through perceptions of disease susceptibility, severity of disease consequences, benefits of preventive actions, perceived barriers, and cues to action. The Knowledge-Attitude-Practice Framework provides a basis for understanding how health education can improve knowledge and influence health-related practices. Community Participation Theory emphasizes the involvement of community members, local leaders, community health workers, and other stakeholders in identifying health risks and implementing appropriate community health interventions. Collectively, these theoretical perspectives provide a suitable framework for explaining how community health education may influence cholera prevention practices among residents of high-risk communities. The study will adopt a quantitative quasi-experimental research design. Residents of selected high-risk communities will participate in a structured community health education programme and will be assessed before and after the intervention. A multistage sampling technique will be employed to select states, local government areas, high-risk communities, households, and eligible adult residents. The health education intervention will cover cholera transmission, signs and symptoms, safe drinking-water practices, household water treatment, safe water storage, hand hygiene, sanitation, food hygiene, environmental cleanliness, proper waste disposal, avoidance of contaminated food and water, early recognition of suspected cholera cases, appropriate healthcare seeking, and measures for reducing household transmission. Community health education exposure will be assessed using indicators such as participation in health education sessions, frequency of sessions, duration of education, exposure to health messages, practical demonstrations, and access to educational materials. Cholera prevention practices will be assessed using indicators such as household water treatment, safe water storage, handwashing practices, sanitation and toilet use, food hygiene, waste disposal, environmental cleaning, avoidance of unsafe water sources, and timely healthcare seeking for suspected cholera symptoms. Where feasible, observational checklists will be used to complement self-reported practices and assess household water-storage, sanitation, and hygiene conditions. Descriptive statistics will be used to summarize participants' characteristics, baseline knowledge, and prevention practices. Inferential statistical techniques, including paired-sample tests, chi-square tests, correlation analysis, and regression analysis, will be used to determine the effect of community health education on cholera prevention practices. Diagnostic tests will also be conducted to assess the reliability of the research instrument and the robustness of the findings. The study is expected to find that community health education has a significant positive effect on cholera prevention practices among residents of high-risk communities in Nigeria. Residents exposed to structured health education are expected to demonstrate improved adoption of safe water, sanitation, hygiene, food-safety, and environmental health practices compared with their baseline practices. Education is expected to improve residents' understanding of how cholera is transmitted and strengthen their ability to identify practical measures for reducing exposure to contaminated water and food. Practical demonstrations of household water treatment, safe water storage, proper handwashing, and environmental sanitation are expected to improve the adoption of recommended preventive behaviours. The intervention may also encourage earlier healthcare seeking among individuals who develop symptoms consistent with cholera. Conversely, limited health education may contribute to inadequate knowledge and inconsistent adoption of recommended prevention practices. However, health education alone may not fully determine cholera prevention practices because access to safe water, sanitation facilities, household income, environmental conditions, availability of water-treatment materials, healthcare accessibility, and community infrastructure may also influence behaviour. Therefore, community health education should be accompanied by improvements in water, sanitation, and hygiene infrastructure. The study is expected to contribute to the literature on community health education, cholera prevention, environmental health, water sanitation and hygiene, epidemiology, health promotion, community health, and disease prevention in Nigeria by providing empirical evidence on the role of health education in reducing cholera-related risks in high-risk communities. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Nigeria Centre for Disease Control and Prevention, National Primary Health Care Development Agency, state ministries of health, local government health authorities, environmental health departments, primary healthcare centres, community health workers, traditional and community leaders, humanitarian organizations, development partners, and policymakers regarding strategies for preventing cholera transmission. The study will also provide evidence-based recommendations for strengthening community health education programmes, expanding household water-treatment education, promoting safe water storage, improving hand hygiene and sanitation practices, strengthening community disease surveillance, improving early healthcare seeking, and integrating health education with water, sanitation, and hygiene interventions in high-risk communities across Nigeria.
