This paper examines how infrastructural facilities provision has affected the urban development of Akure, Nigeria. The study adopts the survey research design (SRD) method to investigate the nexus with the aid of a structured questionnaire on sampled households, as well as personal interviews, observations and photos to narrate the existing situation. The average number of households in Akure was estimated at 95,232, of which 1 per cent (representing 952 households) were systematically sampled. Findings reveal unguided expansion in the growth of the city and uneven distribution of facilities across the city zones. The irregular population influx and increased urban sprawl experienced in the city has been attributed to the massive provision of infrastructural facilities in the recent past at the expense of rural contiguous settlements. Meanwhile, this uneven distribution of infrastructural facilities has significantly affected their functionality, as well as security, housing and transport systems within the city. To mitigate this, the study suggests a corresponding increase in the provision of facilities in the city and in the hinterlands to curb the incessant rural influx into the city. Also, as the city expands, the facilities need to be increased and maintained for maximum utilisation and functionality. [ABSTRACT FROM AUTHOR]

The global population influx during the COVID-19 pandemic poses significant challenges to public health, making the prevention and control of infectious diseases a pressing concern. This paper aims to examine the impact of population influx on the spread of infectious diseases, with a specific emphasis on the mediating role of air pollution in this process. A theoretical analysis is conducted to explore the relationship between population influx, air pollution, and infectious diseases. Additionally, we establish a series of econometric models and employ various empirical tests and analytical techniques, including mediation effect test, threshold effect test, and systematic GMM test, to evaluate our hypotheses. The results indicate that: (1) Population influx directly and indirectly impacts infectious diseases. Specifically, population influx not only directly elevates the risk of infectious diseases, but also indirectly increases the incidence rate of infectious diseases by intensifying air pollution. (2) The impact of population inflow on infectious diseases exhibits regional heterogeneity. Compared to central and western China, the eastern regions exhibit a significantly higher risk of infectious diseases, exceeding the national average. (3) External factors influence the relationship between population influx and infectious diseases differently. Personal income and medical resources both help mitigate the risk of infectious diseases due to population influx, with medical resources having a more substantial effect. Contrary to expectations, abundant educational resources have not reduced the risk, instead, they have exacerbated the risk associated with population influx. This paper provides a scientific basis for formulating effective strategies for the prevention and control of infectious diseases.
