Background: Over the years, incidences of dengue fever (DF) and hemorrhagic (DHF) reported in Vietnam have been on rise. Therefore, objective study is to investigate use a Geographic Information System (GIS) infectiou disease mapping. Methods: Histogram Getis Ord’s statistic will be employed analyze spatial distribution DHF. More specifically, histogram firstly used statistic-based autocorrelation analysis then applied detect hotspots Spatial DHF hotspot mapped with help GIS. Finally, August 2023 Ho Chi Minh city discussed. Results: it was found that total 3 1 coldspot successfully detected. Three incidence were identified most dense intense city's residential zoning districts west south including District 4 (11 cases/100,000 people), Binh Chanh (16 Can Gio (5 people). Whereas, also detected Tan Phu (24 district center. Conclusions: Findings this confirm effectiveness GIS infectious mapping incidence.

This took into account not only aspects but also COVID-19-related outcomes (infections deaths) allowing discern potential influencing role per type outcome. A total 112 scientific articles were selected, reviewed categorized according subject area, aim, country/region study, considered variables, spatial temporal units analysis, methodologies, main findings. Our showed features may have played a determining uneven geography COVID-19; for instance, certain agreement was found regarding direct relationship between urbanization degree infections.

Methods Generalized additive models were used map risk from March 2020 February 2021 in Orange County (OC), California. We geocoded analyzed 221,843 OC census tracts within a Poisson framework while smoothing over tract centroids.

At the end of year 2019, a virus named SARS-CoV-2 induced coronavirus disease, which is very contagious and quickly spread around world. This new infectious disease called COVID-19. Numerous areas, such as economy, social services, education, healthcare system, have suffered grave consequences from invasion this deadly virus. Thus, thorough understanding COVID-19 required in order to deal with outbreak before it becomes an disaster. In research, daily reported cases 92 sub-districts Johor state, Malaysia, well population size associated each sub-district, are used study propagation across space time Johor.

Understanding development incidence spatiotemporal patterns at neighborhood level is crucial for local authorities identify high-risk areas develop tailored mitigation strategies. However, analyses are scarce mostly limited specific phases pandemic. aim this study was explore scale an intra-urban setting over several (March 2020–December 2021). We used reported case data from department district Berlin-Neukölln, Germany, additional socio-demographic data, text documents materials on implemented measures. examined time context measures other with particular focus age groups. maps spatial scan statistics reveal changing patterns. Our results show that factors may influenced incidence. In particular, far-reaching contact reduction showed substantial impact Neukölln. observed group-specific effects: school closures had effect younger population (< 18 years), whereas start vaccination campaign primarily among elderly (> 65 years). analysis revealed were heterogeneously distributed across district. location also changed phases. study, existing studies supplemented our investigation course underlying processes small long period time. findings provide insights authorities, community planners, policymakers about level.

During the SARS-CoV-2 pandemic, governments and public health authorities collected massive amounts of data on daily confirmed positive cases incidence rates. These sets provide relevant information to develop a scientific understanding pandemic’s spatiotemporal dynamics. At same time, there is lack comprehensive approaches describe classify patterns underlying dynamics COVID-19 across regions over time. This seriously constrains potential benefits for understand disease that would allow better risk communication strategies improved assessment mitigation policies efficacy. Within this context, we propose an exploratory statistical tool combines functional analysis with unsupervised learning algorithms extract meaningful about main mainland Portugal. We focus timeframe spanning from August 2020 March 2022, considering at municipality level. First, temporal evolution by as function outline variability using principal component analysis. Then, municipalities are classified according their similarities through hierarchical clustering adapted spatially correlated data. Our findings reveal disparities in between northern coastal versus those southern hinterland. also distinguish effects occurring during 2020–2021 period 2021–2022 autumn-winter seasons.

Abstract Low socio-economic status is associated with higher SARS-CoV-2 incidences. In this paper we study whether a result of differences in (1) the frequency, (2) intensity, and/or (3) duration local outbreaks depending on housing situations. So far, there not clear evidence which three factors dominates. Using small-scale data from neighborhoods German city Essen and flexible estimation approach does require prior knowledge about specific transmission characteristics SARS-CoV-2, behavioral responses or other potential model parameters, find for last hypotheses. Outbreaks do happen more often less well-off areas are severe (in terms number cases), but they longer. This indicates that gradient infection levels at least parts sustained spread infections worse conditions after suggests case an epidemic allocating scarce resources containment measures to poor might have greatest benefit.

Preemptive wait-listing of deceased donor kidney transplant (DDKT) candidates before maintenance dialysis increases the likelihood transplantation and improves outcomes among patients. Previous studies have identified substantial disparities in rates preemptive listing, but a gap exists examining geographic sources disparities, particularly for sub-regional units. Identifying small area hot spots where delayed listing is prevalent may more effectively inform both health policy regionally appropriate interventions.
