Background of the Study
Typhoid fever, caused by Salmonella typhi, is a significant public health issue in Nigeria, particularly in states with inadequate water sanitation and hygiene (WHO, 2024). The disease is primarily transmitted through contaminated water and food, with poor sanitation being a major risk factor (UNICEF, 2024). Plateau State, located in central Nigeria, has a high burden of typhoid fever, largely due to inconsistent access to clean water and improper waste disposal practices (Ogbonna & Musa, 2024).
Water quality plays a crucial role in typhoid fever transmission. In many parts of Plateau State, residents rely on unprotected wells, rivers, and boreholes for drinking water, increasing the risk of infection (NCDC, 2024). Limited access to proper sanitation facilities and inadequate public health infrastructure further exacerbate the situation. According to a recent survey, many communities in Plateau State lack adequate water treatment systems, leading to frequent outbreaks of waterborne diseases, including typhoid fever (Ahmed et al., 2024).
Despite government initiatives to improve water supply and sanitation, typhoid fever remains a persistent health challenge. Understanding the relationship between water quality and typhoid prevalence is essential for developing effective intervention strategies. This study aims to evaluate the burden of typhoid fever in Plateau State in relation to water quality, assessing the impact of contaminated water on disease prevalence.
Statement of the Problem
Typhoid fever continues to pose a serious health threat in Plateau State, with high morbidity and mortality rates, particularly in rural communities (WHO, 2024). The major contributing factor to the high burden of typhoid is the poor quality of drinking water, which exposes residents to Salmonella typhi infection. Many households depend on untreated water sources, while inadequate sanitation infrastructure worsens the spread of the disease (UNICEF, 2024).
Despite various interventions to improve water supply and hygiene practices, typhoid fever outbreaks remain frequent. The effectiveness of existing water sanitation programs in reducing typhoid prevalence in Plateau State is unclear due to limited region-specific research. This study seeks to address this knowledge gap by evaluating the relationship between water quality and typhoid fever prevalence, providing evidence-based recommendations for improving water safety and reducing disease burden.
Objectives of the Study
1. To assess the prevalence of typhoid fever in Plateau State.
2. To analyze the relationship between water quality and typhoid infection rates.
3. To evaluate the effectiveness of water sanitation interventions in reducing typhoid fever.
Research Questions
1. What is the prevalence of typhoid fever in Plateau State?
2. How does water quality affect the incidence of typhoid fever in Plateau State?
3. How effective are current water sanitation interventions in controlling typhoid outbreaks?
Research Hypotheses
1. Poor water quality is significantly associated with high typhoid fever prevalence in Plateau State.
2. Communities that rely on untreated water sources have a higher incidence of typhoid fever.
3. Improved water sanitation measures will lead to a reduction in typhoid fever cases in Plateau State.
Scope and Limitations of the Study
This study will focus on selected communities in Plateau State with varying access to clean water. It will assess typhoid fever prevalence and examine the impact of water quality on disease transmission. Limitations may include reliance on self-reported data and potential challenges in accessing remote areas for water testing.
