“…Understanding the spread dynamics of infectious diseases is of utmost importance in the anticipation and control of their epidemics [ 42 ]. In this study, although the processes of diffusion of cholera epidemics from source areas are multidirectional, main likely routes of spread have emerged as preferential trajectories.…”

Cholera is endemic along the Great Lakes Region, in eastern Democratic Republic of the Congo (DRC). From these endemic areas, also under perpetual conflicts, outbreaks spread to other areas. However, the main routes of propagation remain unclear. This research aimed to explore the modalities and likely main routes of geographic spread of cholera from endemic areas in eastern DRC. We used historical reconstruction of major outbreak expansions of cholera since its introduction in eastern DRC, maps of distribution and spatiotemporal cluster detection analyses of cholera data from passive surveillance (2000–2017) to describe the spread dynamics of cholera from eastern DRC. Four modalities of geographic spread and their likely main routes from the source areas of epidemics to other areas were identified: in endemic eastern provinces, and in non-endemic provinces of eastern, central and western DRC. Using non-parametric statistics, we found that the higher the number of conflict events reported in eastern DRC, the greater the geographic spread of cholera across the country. The present study revealed that the dynamics of the spread of cholera follow a fairly well-defined spatial logic and can therefore be predicted.

“…Tal conexión ha producido lo que en geografía se ha denominado corrientemente como el proceso de difusión espacial, que se desencadena producto de la interacción y conexión entre personas, la cual se puede comprender como un fenómeno de propagación en el tiempo y espacio de una cosa especí ca, objetivo, institución, idea, etc., por medio de individuos, grupos o cualquier otra entidad potencial de acoger localmente lo anterior (Pumain y Saint-Julien, 2001). Por lo tanto, a medida que se incrementan las conexiones entre territorio debido a tales relaciones de intercambio, también aumenta el contacto entre habitantes y, por ende, tal proceso de difusión espacial, trayendo consigo no sólo la propagación de ideas, tecnología y otros, sino que también la propagación de virus en distintos periodos de la historia humana (Congdon, 2016;Saccomandi, 1997).…”

“…The spread of an infectious disease is an instance of spatiotemporal diffusion processes at work, in which the emergence of the disease moves across space and changes in extent over time [25]. Geographic information systems (GIS) offer a means to visualize, analyze and understand the distribution of infectious diseases over space and time, thereby revealing spatiotemporal trends, patterns and associations between the pathological factors and the geographic environments of the disease [26,27].…”

Middle East respiratory syndrome coronavirus (MERS-CoV) is a great public health concern globally. Although 83% of the globally confirmed cases have emerged in Saudi Arabia, the spatiotemporal clustering of MERS-CoV incidence has not been investigated. This study analysed the spatiotemporal patterns and clusters of laboratory-confirmed MERS-CoV cases reported in Saudi Arabia between June 2012 and March 2019. Temporal, seasonal, spatial and spatiotemporal cluster analyses were performed using Kulldorff’s spatial scan statistics to determine the time period and geographical areas with the highest MERS-CoV infection risk. A strongly significant temporal cluster for MERS-CoV infection risk was identified between April 5 and May 24, 2014. Most MERS-CoV infections occurred during the spring season (41.88%), with April and May showing significant seasonal clusters. Wadi Addawasir showed a high-risk spatial cluster for MERS-CoV infection. The most likely high-risk MERS-CoV annual spatiotemporal clusters were identified for a group of cities (n = 10) in Riyadh province between 2014 and 2016. A monthly spatiotemporal cluster included Jeddah, Makkah and Taif cities, with the most likely high-risk MERS-CoV infection cluster occurring between April and May 2014. Significant spatiotemporal clusters of MERS-CoV incidence were identified in Saudi Arabia. The findings are relevant to control the spread of the disease. This study provides preliminary risk assessments for the further investigation of the environmental risk factors associated with MERS-CoV clusters.

Spatiotemporal Frameworks for Infectious Disease Diffusion and Epidemiology

Abstract: Emerging infectious diseases, and the resurgence of previously controlled infectious disease (e.g., malaria, tuberculosis), are a major focus for public health concern, as well as providing challenges for establishing aetiology and transmission. [...]
