Health is a fundamental right intricately linked to geographical factors, as evidenced in the health geography literature. The application of information systems (GISs) plays pivotal role mapping diseases and evaluating healthcare accessibility acknowledged by World Organisation solution for enhancing system resilience achieving universal coverage. This study focuses on perspectives provide insights into evolving GIS addressing challenges shaping strategies research within India. primary objective was analyse utilisation GISs studies specifically three thematic areas: disease surveillance, risk assessment, access. databases were searched using sixteen keywords peer-reviewed articles published during 2000–2022. A systematic literature survey conducted, drawing from available PubMed, Web Science Scopus databases. Out 162 search results, 58 selected review after rounds eliminations based predefined specific criteria. conducted following PRISMA guidelines two questions. reveals extensive use since its inception, with particular prominence decision-making tool aftermath COVID-19 outbreak. analysis scientific focused access Indian context demonstrates effectiveness managing planning resources services. has proven be an indispensable instrument understanding spatial patterns optimising interventions. underscores critical research, particularly context. versatile applications highlight strategies, contributing more resilient accessible India beyond.

Infectious diseases are a global public health problem that poses threat to human society. Since the 1970s, constantly mutated new infectious viruses have been quietly attacking humanity, and at least one type of disease is discovered every year. Therefore, early warning will greatly reduce socio-economic harm diseases. This study based on data COVID-19 epidemic in China (except Macau Taiwan Province) from 2020 2022. Firstly, we used ArcGIS software analyze spatial agglomeration pattern number patients various regions through autocorrelation analysis, local center gravity trajectory migration algorithm other statistical tools; In addition, areas with serious requiring special attention were screened out. Then, autoregressive integrated moving average model (ARIMA), extreme learning machine (ELM), support vector regression (SVR), wavelet neural network (Wavelet), recurrent (RNN) long short-term memory (LSTM) predict Guangdong Province, China; And prediction performance each was compared accuracy indicators. Finally, multi fusion stacking technology proposed address poor generalization ability single models prediction; Furthermore, radial basis function (RBF) as two-level meta learner fuse above models, particle swarm optimization (PSO) optimize RBF parameters error. The experimental results show better than dataset. order apply diseases, applied dataset AIDS pulmonary tuberculosis (PTB) cases, verified wide applicability our

Abstract The global COVID‐19 outbreak severely hampered the growth of economy, prompting implementation strictest prevention policies in China. Establishing a significant relationship between changes nighttime light and lockdowns from geospatial perspective is essential. In remote sensing, we evaluated spatiotemporal dynamic effects city on human activity intensity Zhengzhou region. Prior to outbreak, region maintained trend, even under regular control measures. However, following October 2022 lockdown, experienced substantial decrease. central area Zhengzhou, decreased by at least 18% compared pre‐lockdown levels, while sub‐center, decrease was around 14%. areas where most were primarily within 15 km radius, concentrated 5 radius. These both statistical data underscored impact lockdown economic activities

COVID-19 has been the most widespread and far-reaching public health emergency since beginning of 21st century. The Chinese lockdown comprehensive strict in world. Based on Shanghai outbreak 2022, we analyzed heterogeneous impact human activities urban economy using monthly nighttime light data. We found that Yangtze River Delta is very obvious. number counties Shanghai, Jiangsu, Zhejiang Anhui showing a downward trend MNLR (Mean Nighttime Light Radiation) 100%, 97%, 99% 85%, respectively. Before COVID-19, proportion with was 19%, 67%, 22% 33%, Although some also decreased 2019, scope intensity far less than 2022. Under regular containment (2020 2021), showed significant increase (MNLR change > 0). According to NLRI (Nighttime Radiation Influence), significantly affected surrounding provinces (Average < Jiangsu province other Shanghai.

The spatial distribution of the COVID-19 infection rate in city Palma (Balearic Islands) is analyzed from geolocation positive cases by census tract and its relationship with socioeconomic variables evaluated. Data on infections have been provided Health Service Ministry Consumption Government Balearic Islands. study combines several methods analysis: autocorrelation, calculation Gini index least squares regression, weighted geographical regression. results show that pandemic comprised five waves March 2020-March 2022 period, corresponding to months April 2020, August December July 2021, January 2022. Each wave shows a particular pattern, however, second third higher levels concentration. In this sense, wave, affecting peripheral neighborhoods eastern part city. confirms imbalances first pandemic. addition, regression models indicate most significant prediction are average income, percentage children under 18 years age, size household, single-person households. economic had clear influence pattern distribution.

Abstract It is so far unclear how the COVID-19 winter waves started and what should be done to prevent possible future waves. In this study, we deciphered dynamic course of a wave in 2021 Saxony, state Eastern Germany neighbouring Czech Republic Poland. The study was carried out through integration multiple virus genomic epidemiology approaches track transmission chains, identify emerging variants investigate changes clusters. For identified local interest, functional evaluations were performed. Multiple long-lasting community clusters have been acting as driving force for 2021. Analysis courses two representative indicated similar pattern. However, cluster caused by locally occurring new Delta variant AY.36.1 showed distinct pattern, analyses revealed replication advantage it. This that starting since early autumn imported or all contributed development wave. information achieved might help pandemic prevention.

Abstract In winter 2020 and 2021 many countries worldwide experienced a COVID-19 pandemic wave which led to severe burdens on healthcare systems huge economic losses. Yet, it remains unclear how the waves started debates are ongoing about actions necessary prevent future waves. this study we deciphered dynamic course of in Saxony, state Eastern Germany neighboring Czech Republic Poland. The information achieved might help prevention. Saxony was investigated through integration multiple virus genomic epidemiology approaches functional evaluations locally circulating variants. Through international collaborations, performed analysis weekly base with samples from also one neighbor region Republic. Phylogeny analyses were used track transmission chains, monitor genetic changes identify emerging Phylodynamic have been applied clusters. For identified local variants interest, active viruses isolated performed. Genomic studies revealed long-lasting community clusters acting as major driving forces for 2021. Analysis courses two representative indicated similar changes. first 6-8 weeks, relevant variant mainly small among young middle-aged people; after eight ratio people aged above 60 years infected population markedly increased, got more widely spread distant regions. On other hand, cluster caused by occurring showed different pattern. It geographically distributed within six being since beginning cluster, indicating higher risk escalating burdens. This displayed relative growth advantage compared co-circulating Delta sub-lineages. Functional replication advantage, but no immune evasion ability. that starting between August October imported well all contributed development Saxony. particular, derived certain stressed systems.
