Viral infectious diseases,characterized by their intricate nature and wide-ranging diversity,pose substantial challenges in the domain of data management.The vast volume of data generated by these diseases,spanning from the molecular mechanisms within cells to large-scale epidemiological patterns,has surpassed the capabilities of traditional analytical methods.In the era of artificial intelligence(AI)and big data,there is an urgent necessity for the optimization of these analytical methods to more effectively handle and utilize the information.Despite the rapid accumulation of data associated with viral infections,the lack of a comprehensive framework for integrating,selecting,and analyzing these datasets has left numerous researchers uncertain about which data to select,how to access it,and how to utilize it most effectively in their research.This review endeavors to fill these gaps by exploring the multifaceted nature of viral infectious diseases and summarizing relevant data across multiple levels,from the molecular details of pathogens to broad epidemiological trends.The scope extends from the micro-scale to the macro-scale,encompassing pathogens,hosts,and vectors.In addition to data summarization,this review thoroughly investigates various dataset sources.It also traces the historical evolution of data collection in the field of viral infectious diseases,highlighting the progress achieved over time.Simultaneously,it evaluates the current limitations that impede data utilization.Furthermore,we propose strategies to surmount these challenges,focusing on the development and application of advanced computational techniques,AI-driven models,and enhanced data integration practices.By providing a comprehensive synthesis of existing knowledge,this review is designed to guide future research and contribute to more informed approaches in the surveillance,prevention,and control of viral infectious diseases,particularly within the context of the expanding big-data landscape. 展开更多

[Objective]To design and express a recombinant protein rMKIBV incorporating confirmed antigenic epitopes of infectious bronchitis virus(IBV)as a vaccine to provide comprehensive protection.Additionally,it explores the potential of polyclonal yolk antibodies(IgY)harvested from laying hens immunized with the rMKIBV vaccine in the prevention and control of IBV.[Methods]The antigenic epitope sequences of IBV,obtained from online databases,were compared with sequences of representative IBV strains from GenBank.Flexible peptides were designed to link all antigenic peptides.The constructed amino acid sequence was analyzed,reverse-translated,codon-optimized,and then inserted into the pET-28a(+)cloning vector.The recombinant vector was introduced into Escherichia coli for expression.The purified,desalted,and endotoxin-removed rMKIBV protein was used as a vaccine to immunize animals for investigation of its immunogenicity and ability to stimulate specific IgY production in laying hens.[Results]The retrieved IBV antigenic epitope sequences showed high similarity with the published N and S protein sequences of 22 representative IBV strains.The predicted isoelectric point and molecular weight of rMKIBV were 10.25 and 63.39 kDa,respectively.The secondary structure of rMKIBV included a high proportion of random coils,which suggested strong antigenicity.High-purity rMKIBV was obtained from E.coli transformed with the recombinant plasmid pET-28a-mkibv.This protein specifically bound to anti-His-tag antibodies,N protein antibodies,and S protein antibodies.The mice immunized with this protein showed increases in the spleen index(P<0.05),elevations in the levels of serum-specific IgG antibodies(P<0.01)and IFN-γ(P<0.05),and no significant change in the IL-2 level.Immunized laying hens successfully produced IgY in egg yolks,with specific IgY antibody levels significantly increasing.Moreover,the IgY antibody titer gradually rose after immunization,reaching the peak after about 50 days and then gradually declining to reach a stable level.[Conclusion]We successfully constructed and expressed the recombinant protein rMKIBV.The protein demonstrated good immunogenicity,stimulating specific antibody production in both mice and laying hens.Notably,the IgY extracted from the yolks of immunized laying hens offers a novel approach to IBV prevention and control.These findings hold significant scientific and practical value for the development of vaccines against IBV. 展开更多

Climate and weather significantly influence the duration,timing,and intensity of disease outbreaks,reshaping the global landscape of infectious diseases.Rising temperatures and shifts in precipitation patterns driven by climate change can directly impact the survival and reproduction of pathogens and vector organisms.Moreover,climate change is expected to exacerbate extreme weather events,including floods and droughts,which can disrupt infrastructure and increase the risk of waterand foodborne diseases.There are potential shifts in the temporal and spatial patterns of infectious disease transmission owing to climate change.Furthermore,climate change may alter the epidemiology of vaccine-preventable diseases.These climatic variations not only affect the ecological characteristics of pathogens and vectors but also indirectly influence human behaviors and socioeconomic conditions,further amplifying disease transmission risks.Addressing this challenge requires an interdisciplinary collaboration and comprehensive public health strategies.This review aims to synthesize the current evidence on the impact of climate change on climate-sensitive infectious diseases and elucidate the underlying mechanisms and transmission pathways.Additionally,we explored adaptive policy strategies to mitigate the public health burden of infectious diseases in the context of climate change,offering insights for global health governance and disease control efforts. 展开更多

Folate(FA)is an essential micronutrient of vitamin B group for growth,development,and reproduction through participating in the nucleotide synthesis and methyl donation reactions.The changes of FA level have been linked to dietary insufficiency(e.g.,poor diet,etc.)malabsorption(e.g.,FA-associated gene mutation,etc.),increased demand(e.g.,pregnancy,etc).or medication(e.g.,antifolates drugs),or bad habits(e.g.,smoking,alcoholism,etc.).Recently,epidemiological data showed that the levels of the host FA typically changed in patients with infectious diseases.Interactions between pathogens,including bacteria,parasites and viruses,and their hosts are complex,in particular,pathogenic infection-mediated changes of the host FA levels can affect the utilization and uptake of limited FA resources of the host.Therefore,FA supplementation or the use of antifolate agents may be a potential antimicrobial strategy for managing infectious diseases.Furthermore,given that the gut microbiota is a primary source of FA in the human body,the association between gut microbiota and pathogenic infections warrants investigation.To date,little is known about how FA status and its biochemistry function affect the course of infectious diseases.In this review,we focus on the roles of FA in the interaction between the host and microbe,and briefly discuss the potential of FA and antifolates agents in the treatment of infectious diseases. 展开更多

Leontopodium alpinum is a traditional alpine medicinal plant,is extensively used in Tibetan and Mongolian medicine.Its applicability in managing febrile epidemics and respiratory conditions requires deeper study,especially given the recurring threat of infectious diseases.This study uses bibliometric analysis to examine the current state and trends in Leontopodium alpinum research,integrates scattered information,and suggests pathways for subsequent investigation.This study retrieved Chinese literature from the China National Knowledge Infrastructure(CNKI)platform and international literature from the Web of Science(WoS),with data collection finalized by March 2025.CiteSpace 6.3.R1 and VOSviewer 1.6.20 were used to visually analyze publication trends,keyword co-occurrence,and author collaboration networks.The analysis has found that Chinese publications rose markedly after 2003 but declined after 2019,focusing largely on chemical components–such as chlorogenic acid and volatile oils–and pharmacological activities.International output,though smaller,grew steadily,with an emphasis on compositional analysis and antioxidant effects.Keyword clustering revealed that both Chinese and global research expanded from foundational taxonomy to chemical constituents,bioactivity,and environmental adaptation.Core author and institutional analyses identified Liaoning University of Traditional Chinese Medicine and the University of Chinese Academy of Sciences as domestic leaders,while the University of Innsbruck(Austria)played a leading international role.In conclusion,this study offers the first systematic summary of research and publishing trends for Leontopodium alpinum,while also identifying key knowledge gaps.Future studies should prioritize multi-omics approaches to clarify the mechanisms of its bioactive compounds and advance clinical application.Due to its notable efficacy against febrile epidemics and respiratory diseases,expanded research is strongly recommended–particularly in light of rising infectious disease risks where this species could serve an essential role. 展开更多

Extracellular vesicles(EVs)have arisen as potential therapeutic tools in managing infectious diseases because EVs can regulate cell-to-cell signaling,function as drug transport mechanisms,and influence immune reactions.They are obtained from a myriad of sources,such as plants,humans,and animal cells.EVs like exosomes and ectosomes can be utilized in their native form as therapeutics or engineered to encompass antimicrobials,vaccines,and oligonucleotides of interest with a targeted delivery strategy.An in-depth understanding of host-pathogen dynamics provides a solid foundation for exploiting its full potential in therapeutics against infectious diseases.This review mainly offers an extensive summary of EVs,comprising their various origins,formations,and pathogen relationships.It further provides insights into the various techniques utilized in isolating and engineering these vesicles to target infectious diseases and how challenges involving large-scale production and cargo loading efficiency should be addressed for clinical application.Finally,preclinical and clinical implementations of EVs derived from animals,plants,and microorganisms are elucidated,stressing their promise for designing innovative antimicrobial approaches. 展开更多

Governments worldwide have implemented non-pharmaceutical interventions(NPIs)to control the spread of coronavirus disease 2019(COVID-19),and it is crucial to accurately assess the effectiveness of such measures.Many studies have quantified the risk of infection transmission and used simulations to compare the risk before and after the implementation of NPIs to judge policies’effectiveness.However,the choice of metric used to quantify the risk can lead to different conclusions regarding the effectiveness of a policy.In this study,we analyze the correlation between different transmission-risk metrics,pedestrian environments,and types of infectious diseases using simulation-generated data.Our findings reveal conflicting results among five different metric types in specific environments.More specifically,we observe that,when the randomness of pedestrian trajectories in indoor spaces is low,the closeness centrality exhibits a higher correlation coefficient with infection-based metrics than with contact-based metrics.Furthermore,even within the same pedestrian environment,the likelihood of discrepancies between infection-based metrics and other metrics increases for infectious diseases with low transmission rates.These results highlight the variability in the measured effectiveness of NPIs depending on the chosen metric.To evaluate NPIs accurately,facility managers should consider the type of facility and infectious disease and not solely rely on a single metric.This study provides a simulation model as a tool for future research and improves the reliability of pedestrian-simulation-based NPI effectiveness analysis methods. 展开更多

Ligularia jaluensis is an important medicinal and ornamental plant in China.However,the viruses capable of infecting Ligularia jaluensis remains unknown.Here,we identified a novel carlavirus,tentatively named ligularia jaluensis carlavirus(LJCV),as well as a known iris severe mosaic virus(ISMV),in L.jaluensis plants displaying chlorosis and yellow ring spot symptoms,using RNA-seq analysis.The LJCV genome consists of an 8497 nt positive-sense,single-stranded RNA[excluding the poly(A)tail],and contains six open reading frames(ORFs).Phylogenetic analyses based on the fulllength genome and RNA-dependent RNA polymerase(RdRp)amino acid(aa)sequences revealed that LJCV clusters within an evolutionary branch alongside known viruses in the Carlavirus genus.The RdRp protein encoded by ORF1 of LJCV shared 45.38%–67.41%identity with the corresponding proteins of eight closely related carlaviruses.ORFs 2–4 constitute the triple gene block(TGB),with TGBp1 and TGBp3 localized in the endoplasmic reticulum(ER),while TGBp2 is localized at plasmodesmata(PD)and facilitates viral intercellular movement,as demonstrated by its ability to complement the potato virus X with movement-deficient mutant(PVX-Δp25-GFP).Additionally,ORF6 encodes a cysteine-rich protein(CRP)that is localized in the chloroplast and functions as a viral pathogenicity factor,inducing severe viral symptoms in the heterologous PVX expression system.Furthermore,we successfully constructed an infectious cDNA clone of LJCV,and found that it can infect Nicotiana benthamiana plants through mechanical inoculation or agrobacterium-mediated infiltration of the LJCV infectious clone.These findings enhance our understanding of the characteristics and host range of carlaviruses,as well as the viruses capable of infecting L.jaluensis. 展开更多

Infectious bronchitis(IB),a highly contagious acute respiratory disease affecting avian species,poses significant challenges to poultry production.The causative agent,infectious bronchitis virus(IBV),exhibits a high mutation rate,leading to limited cross-protection by existing vaccines.This necessitates the development of novel vaccines.This study,based on preliminary investigations conducted by our research team,identified six potential strains(PYG QX1,ZQF QX2,FQH QX3,LYZ QX4,XXX QX5,and CSL strains)for vaccine development.Previous pathogenicity test and serum cross-neutralization experiments conducted in this study have demonstrated that the FQH QX3 strain exhibited the weakest pathogenicity and the broadest spectrum of serum neutralization,while the CSL strain showed the highest pathogenicity and was the most challenging to neutralize,posing the greatest difficulty in prevention and control.Subsequently,we constructed and rescued recombinant vaccine candidates,H120-FQH QX3,and H120-CSL,expressing the S1 and N proteins of the FQH QX3 and CSL strains,respectively.Immunization protection experiments indicated that the H120-CSL recombinant vaccine candidate exhibited the most effective immune protection,making it a promising candidate for further study and evaluation as a recombinant vaccine.The S1 and N genes of the CSL strain demonstrated strong immunogenicity,making them potential candidate antigen genes for future vaccine development. 展开更多

The relationship between genetics and infectious diseases is important in shaping our understanding of disease susceptibility,progression,and treatment.Recent research shows the impact of genetic variations,such as heme-oxygenase promoter length,on diseases like malaria and sepsis,revealing both protective and inconclusive effects.Studies on vaccine responses highlight genetic markers like human leukocyte antigens,emphasizing the potential for personalized immunization strategies.The ongoing battle against drug-resistant tuberculosis(TB)illustrates the complexity of genomic variants in predicting resistance,highlighting the need for integrated diagnostic tools.Additionally,genome-wide association studies reveal antibiotic resistance mechanisms in bacterial genomes,while host genetic polymorphisms,such as those in solute carrier family 11 member 1 and vitamin D receptor,demonstrate their role in TB susceptibility.Advanced techniques like metagenomic next-generation sequencing promise detailed pathogen detection but face challenges in cost and accessibility.A case report involving a highly virulent Mycobacterium TB strain with the pks1 gene further highlights the need for genetic insights in understanding disease severity and developing targeted interventions.This evolving landscape emphasizes the role of genetics in infectious diseases,while also addressing the need for standardized studies and accessible technologies. 展开更多

Rapid and accurate detection of infectious virus particles, not just viral nucleic acid, is essential to avoid unnecessary quarantine and effectively control the spread of viral diseases such as coronavirus disease 2019 (COVID-19), severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS). Real-time quantitative polymerase chain reaction (RT-qPCR) was the most widely used detection technique during the COVID-19 outbreak. However, it cannot discriminate between intact infectious viruses and surface-distorted, non-infectious virus particles or naked viral RNA. In this study, we present a strategy for the specific detection of infectious coronaviruses by combining viral receptor capture and reverse transcription loop-mediated isothermal amplification (RT-LAMP). We successfully applied this strategy to detect infectious virus particles of the SARS-CoV-2 surrogate virus and the human coronavirus NL63 (HCoV-NL63). Virus particles were first captured on ELISA plates coated with the recombinant human angiotensin-converting enzyme 2 (hACE2) receptor. Viral RNA was then extracted from the particles and detected by RT-LAMP using virus-specific primers. In our experimental setting, the proposed method had a minimum detection limit (LOD) of 90 PFU/mL, sensitivity of 96.2%, and specificity of 100%. Our study provides a proof-of-concept that viral receptor capture combined with RT-LAMP can differentiate infectious coronaviruses from non-infectious virions or naked viral RNA. This paves the way for this virus detection strategy to become a mainstream tool for the management, prevention and control of epidemic coronavirus diseases. 展开更多

Objective:To explore the effect of applying safety culture construction in nursing management of infectious disease areas.Methods:During the one-year period from January 2024 to December 2024,patients admitted to the infectious disease area of our hospital were randomly selected for the study.92 patients were divided into two groups using a computerized double-blind method for intervention.The control group received routine nursing management,while the observation group applied safety culture construction management.The effects of nursing management in the two groups were studied and compared.Results:Before management,the nursing management quality scores of the two groups were evaluated,showing little difference in various scores,and the difference was not statistically significant(P>0.05).Through the implementation of nursing management,the scores of the two groups were significantly improved,and the observation group had significantly higher scores compared to the control group(P<0.05).Compared to the incidence of nursing risk events,the observation group(6.52%)was significantly lower than the control group(30.43%),and there was a significant difference between the two groups(P<0.05).The observation group had significantly higher satisfaction scores for nursing skills,health education,service attitude,and professionalism compared to the control group,indicating patient satisfaction with safety culture construction(P<0.05).Conclusion:Applying safety culture construction in nursing management of infectious disease areas has a preventive effect on nursing risk events and is beneficial for improving patients’risk cognition level. 展开更多
