Here, we conducted metagenomic sequencing to elucidate the composition of microbial communities, ARGs, and examine the co-occurrence patterns between microbes and ARGs across various surfaces in the Shanghai rail transit system. Our findings revealed that bacterial genera such as <em>Rhodococcus, Cutibacterium</em>, and <em>Brevundimonas</em> dominated, originating either from human skin or environmental sources. Notably, the bacterial diversity varied according to the type of surface and specific stations. The principal co-ordinates analysis revealed substantial beta-diversity disparities among the examined surfaces. We identified a total of 1930 ARGs conferring resistance to 20 distinct antibiotic classes, including clinically significant ones such as Aminoglycoside, Streptogramin, Multidrug, and Tetracycline, which are associated with either single or multidrug resistance. Network analysis further revealed the co-occurrence relationships between microbial genera and ARGs. This study highlights that the microbial communities and ARGs in the rail transit system are sustained by a metapopulation of human and environmental generalists. These findings provide novel insights into the mechanisms underlying the risks associated with microbial exposure and suggest strategies to mitigate the spread of pathogenic microorganisms in megacity rail transit systems, thereby enhancing public health.</div></div>","PeriodicalId":73269,"journal":{"name":"Hygiene and environmental health advances","volume":"15 ","pages":"Article 100142"},"PeriodicalIF":2.7,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144842272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We systematically reviewed metrics from 31 studies across environmental, demographic, and socioeconomic dimensions. Our analysis reveals three main challenges: variations in indicator selection, classification, and processing; correlations between indicators and regional characteristics; and inter-metric correlations of conceptual redundancy and oversimplification. These discrepancies and deficiencies may affect the robustness of assessments and increase the difficulty of subsequent discussions, diminishing the policy relevance. Our review identifies and summarizes context-specific indicators, highlights issues of metric redundancy and oversimplification along with corresponding solutions, and establishes guidelines for metric selection.

In recent, the record-breaking environmental temperatures were observed all over the world, especially in the South Asia, Africa, and also in American countries. In Europe, over 70,000 additional deaths have been attributed to heat waves alone in 2022. This extreme climatic event has the implication to health risks and the potential rise in infectious diseases. This review establishes the multifaceted relationship between heat waves and infectious disease dynamics by the integration of existing literature and the emerging evidence from epidemiological, environmental, and laboratory studies. Heat waves create environments that favour the survival and propagation of various pathogens, including viruses, bacteria, protozoa, and fungi, thereby accelerate the speed of microbial biodiversity and evolutionary processes of microbes by progressively altering the ecosystem structures. Heat waves enhance the activity and distribution of insect vectors, leading to higher transmission rates of vector-borne sicknesses like dengue fever, chikungunya, malaria, Zika virus, Lyme disease and West Nile fever etc. Heatwave also could have the correlation to emerging antimicrobial resistance and pathogenic infections. Moreover, human behavioural changes during heat waves, may elevate the risk of food, air and waterborne diseases. However, the review provides a comprehensive understanding of how heat waves influence infectious disease dynamics. This review also emphasizes the need for interdisciplinary research, improved disease surveillance, and globally coordinated climate-health strategies to mitigate the risks.</div></div>","PeriodicalId":73269,"journal":{"name":"Hygiene and environmental health advances","volume":"15 ","pages":"Article 100135"},"PeriodicalIF":0.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144595588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
