Geospatial modeling and analysis of COVID-19 prevalence in Lagos state Nigeria

The impact of COVID-19 pandemic has spatial dimensions which when properly interpreted could lead to better understanding of different characteristics of the pandemic. Thus, the impact of COVID-19 can be mapped for spatial analysis of its attributes. From health science, the research needs include the ability to cross variables of different kinds to interpret the COVID-19 phenomenon, its spatial analysis and spatiotemporal dimensions, its geographical impact on decision-making and everyday life, and predictive modelling of the evolution of the disease. For these reasons, this research aimed at geospatial modelling and analysis of COVID-19 prevalence in Lagos State Nigeria with a view to determine the spread and distribution pattern of COVID-19 as well as its hotspots in Lagos State Nigeria. Its objectives are to: identify and model the spatial distribution of COVID-19 in Lagos State and map the prevalence of COVID-19 in Lagos State. The methodology involved the analysis of the spatial distribution of COVID-19 between 2020 and 2022 and COVID-19 prevalence analysis. Results indicate a substantial surge in confirmed COVID-19 cases, rising from 21,717 to 56,596 during the study period. Alimosho and Eti-Osa LGAs emerged as the most affected regions, reporting the highest total confirmed cases. Additionally, confirmed deaths increased from 4,090 in 2020 to 9,874 in 2022, with Eti-Osa consistently reporting the highest number of fatalities, followed by Ikorodu and Surulere. Assessing the prevalence of confirmed cases and deaths across different LGAs, Eti-Osa consistently exhibited the highest prevalence, indicating a significant proportion of cases and deaths relative to its population.


Introduction
The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has had a profound and far-reaching impact on public health, economies, and societies worldwide.As the pandemic continues to evolve, the importance of understanding its spatial dynamics becomes increasingly evident.Geospatial modeling and analysis have emerged as powerful tools for studying the spread of COVID-19, enabling researchers to investigate the distribution, transmission, and determinants of the virus within specific geographic regions.This research paper focuses on Lagos State, Nigeria, a densely populated and economically significant area, and aims to provide a comprehensive geospatial analysis of COVID-19 prevalence within the state.Lagos State, Nigeria's economic hub and most populous region, presents a unique and complex landscape for the study of COVID-19.Its demographic diversity, urbanization, and transportation networks make it susceptible to disease spread.Lagos State serves as a microcosm of the challenges and opportunities associated with managing a pandemic in a rapidly urbanizing African context.Understanding the spatial dynamics of COVID-19 within Lagos State is essential for effective public health responses, resource allocation, and future pandemic preparedness.
The application of geospatial modeling and analysis techniques to the study of COVID-19 is rooted in a robust and multidisciplinary research tradition.This approach integrates data from various sources, including clinical, epidemiological, environmental, and sociodemographic datasets, and leverages geographic information systems (GIS), remote sensing, and spatial statistics to provide insights into disease transmission, patterns, and risk factors.This research paper builds upon the extensive body of literature that highlights the significance of geospatial analysis in the context of COVID-19 research.The utilization of geospatial data for epidemiological modeling and surveillance has become increasingly relevant (Lau et al., 2020;Tatem, 2020).Moreover, several studies have demonstrated the effectiveness of spatial analysis in understanding the spread of COVID-19 (Li et al., 2020;Pullan et al., 2020).
In the context of Lagos State, there is a growing body of work that recognizes the potential benefits of geospatial analysis in combating COVID-19.Studies have explored the application of geospatial tools for contact tracing, assessing the impact of interventions, and identifying high-risk areas (Adeleke et al., 2020;Ogunlade et al., 2021).Lagos State, with its unique challenges, provides an ideal setting to further investigate the utility of geospatial modeling in understanding COVID-19 transmission.

Study Area
The study area, Lagos State is located between Longitudes 2° 40 E and 4° 15 E and Latitudes 6° 15 N and 6° 45 N, The State took off as an administrative entity on April 11, 1968.However, with the creation of the Federal Capital Territory of Abuja in 1976, Lagos ceased to be the capital of the State.Nevertheless, Lagos remains the nation's economic and the dominant vegetation of the State is the swamp forest of the fresh water and mangrove swamp forests, both of which are influenced by the double rainfall pattern of the state, which makes the environment a wetland region.Generally, the State has two climatic seasons: Dry [November-March] and Wet [April-October].The drainage system of the State is characterized by a maze of lagoons and waterways, which constitutes about 22% or 787 sq.km.[75.755 hectares] of the State's territory.The major water bodies are the Lagos and Lekki Lagoons, Yewa, Ogun, Oshun, and Kweme Rivers.Others are Ologe Lagoon, Kuramo Waters, and Badagry, Five Cowries and Omu Creeks respectively.
