Background of the Study
Population density plays a crucial role in the spread and transmission of infectious diseases. In regions with higher population densities, the likelihood of disease transmission increases due to close human contact, limited access to healthcare, and insufficient public health infrastructure (Oluwaseun et al., 2024). Katsina State, located in northern Nigeria, has witnessed rapid population growth in urban areas, particularly in cities like Katsina and Daura. This population surge, compounded by inadequate health facilities and poor sanitation, has exacerbated the spread of infectious diseases such as cholera, malaria, tuberculosis, and respiratory infections (Ibrahim & Bello, 2025).
Infectious diseases are a significant public health issue in Katsina State, and the relationship between population density and the spread of these diseases needs thorough examination. High population density often results in overcrowding, limited personal space, and increased human interaction, all of which contribute to the rapid transmission of diseases, particularly those that are airborne or waterborne (Bello & Alhaji, 2023). Furthermore, inadequate waste management, poor water supply, and limited vaccination coverage in densely populated areas further increase the vulnerability of residents to infectious diseases (Ola & Mohammed, 2024).
This study aims to investigate the statistical correlation between population density and the spread of infectious diseases in Katsina State, providing evidence to inform policy decisions. A better understanding of this relationship can help public health authorities design more effective interventions to reduce the incidence of infectious diseases in urban areas with high population density.
Statement of the Problem
Despite the increasing population density in Katsina State, the correlation between population density and the spread of infectious diseases has not been extensively studied. This lack of research hinders the ability to understand how population density impacts public health, particularly in densely populated urban areas. There is a need to investigate the link between population density and disease spread to develop targeted interventions for controlling infections in high-risk areas.

Scope and Limitations of the Study
This study will focus on the correlation between population density and the spread of infectious diseases in urban areas of Katsina State. It will include data from health records, demographic information, and public health intervention reports. Limitations include possible inaccuracies in the data due to incomplete health records and challenges in controlling all variables that may influence disease transmission.
