Impact of Flood Preparedness Education on Waterborne Disease Prevention Practices in Flood-Prone Communities in Nigeria

Abstract

Flooding is a recurring environmental and public health hazard in Nigeria, particularly in communities located near rivers, floodplains, coastal areas, and regions with inadequate drainage infrastructure. Flood events can contaminate drinking-water sources, damage sanitation facilities, disrupt healthcare services, and increase exposure to pathogens responsible for waterborne diseases such as cholera, typhoid fever, dysentery, and other diarrhoeal illnesses. Flood preparedness education refers to structured educational activities designed to improve individuals' knowledge and skills regarding flood risks, emergency preparedness, safe water management, sanitation, hygiene, and appropriate actions before, during, and after flood events. Waterborne disease prevention practices refer to behaviours adopted by individuals and households to reduce exposure to pathogens transmitted through contaminated water, food, and the environment. These practices include water treatment, safe water storage, hand hygiene, proper sanitation, food hygiene, avoidance of contaminated water, appropriate waste disposal, and timely healthcare seeking when symptoms of waterborne diseases occur. In flood-prone communities in Nigeria, inadequate knowledge of flood-related health risks and poor preparedness may increase vulnerability to outbreaks of waterborne diseases. Flood preparedness education may strengthen community knowledge, encourage preventive behaviours, improve household readiness, and reduce exposure to contaminated water and unsafe environmental conditions during and after flooding. Against this background, this study investigates the impact of flood preparedness education on waterborne disease prevention practices in flood-prone communities in Nigeria. The study is anchored on the Health Belief Model, Protection Motivation Theory, and Community Participation Theory. The Health Belief Model explains preventive health behaviours through individuals' perceptions of susceptibility to disease, severity of health consequences, benefits of preventive actions, perceived barriers, and cues to action. Protection Motivation Theory explains how awareness of environmental threats and individuals' perceptions of their ability to cope with those threats influence protective behaviours. Community Participation Theory emphasizes the involvement of community members, leaders, health workers, and local organizations in identifying risks and implementing appropriate community-level health interventions. Collectively, these theoretical perspectives provide a suitable framework for explaining how flood preparedness education may influence waterborne disease prevention practices in flood-prone communities. The study will adopt a quantitative quasi-experimental research design. Selected residents from flood-prone communities will participate in a structured flood preparedness education programme and will be assessed before and after the intervention. A multistage sampling technique will be employed to select states, local government areas, flood-prone communities, households, and eligible adult participants. Flood preparedness education will cover flood-related health risks, safe drinking-water practices, household water treatment, safe water storage, sanitation and hygiene during floods, food safety, waste management, environmental cleanliness, avoidance of contaminated floodwater, recognition of symptoms of waterborne diseases, early healthcare seeking, emergency preparedness, and appropriate post-flood hygiene practices. Waterborne disease prevention practices will be assessed using indicators such as household water treatment, boiling or appropriate disinfection of drinking water, use of safe water sources, safe storage of drinking water, handwashing with soap or appropriate alternatives, food hygiene, sanitary toilet use, proper waste disposal, avoidance of contaminated floodwater, environmental cleaning, and timely healthcare seeking for suspected waterborne disease symptoms. Pre-intervention and post-intervention assessments will be compared to determine changes in preventive practices. 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 impact of flood preparedness education on waterborne disease 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 flood preparedness education has a significant positive impact on waterborne disease prevention practices in flood-prone communities in Nigeria. Community members who receive structured flood preparedness 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 awareness of the relationship between flooding, contaminated water, poor sanitation, and waterborne disease transmission and encourage households to treat and safely store drinking water, maintain appropriate hygiene, avoid contaminated water, and seek timely healthcare when symptoms occur. The intervention may also strengthen household preparedness for maintaining safe water and sanitation during periods when normal community services are disrupted by flooding. Conversely, limited knowledge and poor preparedness may increase exposure to contaminated water and unsafe environmental conditions. However, education alone may not fully determine prevention practices because access to safe water, sanitation facilities, household resources, flood severity, availability of water-treatment materials, environmental infrastructure, healthcare access, and emergency assistance may also influence household behaviour. Therefore, flood preparedness education should be accompanied by improvements in water, sanitation, hygiene, and emergency-response infrastructure. The study is expected to contribute to the literature on flood preparedness education, waterborne disease prevention, environmental health, disaster preparedness, health education, community health, epidemiology, and public health in Nigeria by providing empirical evidence on the role of health education in reducing disease risks associated with flooding. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Environment, National Emergency Management Agency, state emergency management agencies, state ministries of health, local government authorities, environmental health departments, primary healthcare agencies, community health workers, development partners, humanitarian organizations, and policymakers regarding strategies for reducing waterborne disease risks in flood-prone communities. The study will also provide evidence-based recommendations for strengthening flood-related health education, developing community preparedness programmes, improving household water-treatment practices, promoting safe water storage, strengthening sanitation and hygiene interventions, improving access to emergency water and sanitation supplies, strengthening community disease surveillance, and integrating public health education into flood preparedness and disaster-response programmes across Nigeria.
