Background of the Study
Cholera is an acute diarrheal disease caused by the bacterium Vibrio cholerae, often linked to poor sanitation, contaminated water sources, and inadequate public health interventions (WHO, 2024). Nigeria has experienced recurrent cholera outbreaks, particularly in states with poor water supply and sanitation infrastructure, such as Taraba State (NCDC, 2024). Cholera outbreaks in the state have been seasonal, with spikes occurring during the rainy season due to flooding and water contamination (Usman et al., 2024).
Despite government and international efforts to control cholera outbreaks through vaccination, sanitation improvements, and emergency response, the disease continues to pose a significant public health challenge in Taraba State (Bello & Okonkwo, 2024). The persistence of these outbreaks suggests underlying socio-environmental and epidemiological factors that need further investigation. Understanding the epidemiological trends of cholera in Taraba State will help identify risk factors, assess the effectiveness of existing interventions, and develop strategies for better disease prevention and control.
Statement of the Problem
Cholera remains a recurrent public health issue in Taraba State, with outbreaks resulting in high morbidity and mortality rates (NCDC, 2024). Despite various intervention programs, the persistence of the disease suggests a gap in understanding its epidemiology, risk factors, and seasonal patterns (WHO, 2024).
Poor access to clean water, inadequate waste disposal systems, and low public health awareness have been identified as major contributors to cholera outbreaks in Nigeria (Bello & Okonkwo, 2024). However, specific data on the epidemiological trends in Taraba State remain limited, making it difficult to implement targeted interventions (Usman et al., 2024). This study seeks to examine the epidemiological trends of cholera outbreaks in Taraba State, identify high-risk areas, and evaluate the effectiveness of cholera control measures.
Objectives of the Study
1. To analyze the epidemiological trends of cholera outbreaks in Taraba State from 2020 to 2025.
2. To identify the socio-environmental factors contributing to recurrent cholera outbreaks in Taraba State.
3. To assess the effectiveness of current cholera prevention and control measures in the state.
Research Questions
1. What are the epidemiological trends of cholera outbreaks in Taraba State between 2020 and 2025?
2. What socio-environmental factors contribute to the persistence of cholera in Taraba State?
3. How effective are current cholera prevention and control measures in Taraba State?
Research Hypotheses
1. There is a significant seasonal variation in cholera outbreaks in Taraba State.
2. Socio-environmental factors such as poor sanitation and contaminated water significantly contribute to cholera outbreaks.
3. Existing cholera prevention and control measures have not significantly reduced the incidence of cholera in Taraba State.
Scope and Limitations of the Study
This study will focus on cholera outbreak data from 2020 to 2025 in Taraba State, examining epidemiological patterns, environmental factors, and control measures. Limitations may include data gaps due to underreporting, variations in healthcare response, and challenges in accessing remote communities.
