The coronavirus disease 2019 (COVID-19) is caused by a new strain of coronavirus that spreads primarily by close contact. Although Nigeria adopted lockdown measures, no defined strategies were used in setting the distance threshold for these lockdowns. Hence, understanding the drivers of COVID-19 is pivotal to an informed decision for containment measures in the absence of vaccines. Spatial and temporal analyses are crucial drivers to apprehending the pattern of diseases over space and time. Thus, this study aimed to quantify the significance of distance to the temporal dynamics of COVID-19 cases in Nigeria using the Geographic Information System. Incremental spatial autocorrelation was used to analyze datasets of each month in ArcGIS. March, April, May, and June exhibited patterns with no significant peaks, while July and August exhibited patterns with two statistically significant peaks. The first and second peaks of July were 301,338.39 and 365,947.83 meters, respectively, while August was 301,338.39 and 336,128.09 meters, respectively. Therefore, a significant difference in the clustering of COVID-19 over distances between July and August was established. This indicated that progression in the spread of the virus increased the virus's spatial coverage while the distance of risk of exposure decreased. This study's findings could be utilized to establish maximum movement restriction areas to contain the spread of COVID-19.

Abstract-ICTThe finding of the study showed that one of IPAs ICTSP aim is to promote innovation in their organization since they are a dynamic and innovative organization. The research also revealed that even though IPA had experienced in ICTSP development and implementation, they were still facing several problems in developing and implementing ICTSP using existing methodologies. The problem is related to the level of easiness and completeness of methodology used and the comprehensiveness of blueprint produce to gain the requested budget from the sponsor. In addition, the research also suggested that there is a need to customize the existing ICTSP methodology to fulfill research institutes unique characteristics and to maximize ICTSP impact to promote innovation in the organization.Index Terms-Strategic information systems planning, ICT strategic planning, SISP methodology, research institutes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
