Ecological Barrier Deterioration Driven by Human Activities Poses Fatal Threats to Public Health due to Emerging Infectious Diseases

The coronavirus disease 2019(COVID-19)and concerns about several other pandemics in the 21st century have attracted extensive global attention.These emerging infectious diseases threaten global public health and raise urgent studies on unraveling the underlying mechanisms of their transmission from animals to humans.Although numerous works have intensively discussed the cross-species and endemic barriers to the occurrence and spread of emerging infectious diseases,both types of barriers play synergistic roles in wildlife habitats.Thus far,there is still a lack of a complete understanding of viral diffusion,migration,and transmission in ecosystems from a macro perspective.In this review,we conceptualize the ecological barrier that represents the combined effects of cross-species and endemic barriers for either the natural or intermediate hosts of viruses.We comprehensively discuss the key influential factors affecting the ecological barrier against viral transmission from virus hosts in their natural habitats into human society,including transmission routes,contact probability,contact frequency,and viral characteristics.Considering the significant impacts of human activities and global industrialization on the strength of the ecological barrier,ecological barrier deterioration driven by human activities is critically analyzed for potential mechanisms.Global climate change can trigger and expand the range of emerging infectious diseases,and human disturbances promote higher contact frequency and greater transmission possibility.In addition,globalization drives more transmission routes and produces new high-risk regions in city areas.This review aims to provide a new concept for and comprehensive evidence of the ecological barrier blocking the transmission and spread of emerging infectious diseases.It also offers new insights into potential strategies to protect the ecological barrier and reduce the wide-ranging risks of emerging infectious diseases to public health.

Advances in Acute Emerging Infectious Disease Symptom Monitoring

In recent years,the risk of acute emerging infectious diseases has increased significantly due to changes in environmental conditions and social factors,posing a serious threat to public health security and human health.The general susceptibility of the population and the unpredictability and increasing infectiousness of emerging infectious diseases reflect the inadequacy of the existing infectious disease surveillance system for timely detection and screening of emerging infectious diseases,often leading to a certain scale of epidemic outbreaks that seriously harm humans before being detected passively.This is a literature review on symptom surveillance of acute emerging infectious diseases at home and abroad,emphasizing on the subject matter and development of symptom surveillance of emerging infectious diseases,so as to provide a scientific basis for the establishment and improvement of symptom surveillance of acute emerging infectious diseases.

Integrating host biological and ecological variables to predict probability of haemosporidian infection in raptors

Variations in host traits that influence their exposure and susceptibility may impact probability of vector-transmitted diseases.Therefore,identifying the predictors of infection probability is necessary to understand the risk of disease outbreaks during expanding environmental perturbation.Here,we conducted a large survey based on microscopic examination and molecular analysis of haemosporidian parasite infection in raptors rescued at the Beijing Raptor Rescue Centre.Combining these data with biological and ecological variables of the raptors,we determined predictors that affect the probability of haemosporidian infection using generalized linear mixed models and multimodel inference.Our results showed that infection probability exhibited considerable variation across host species in raptors,and body mass,sex,and evolutionary history played relatively weaker roles in driving infection probability.Instead,activity pattern,age,geographic range size,migration distance,and nest type were important predictors of the probability of haemosporidian infection,and the role of each predictor differed in the three main haemosporidian genera(Plasmodium,Haemoproteus,and Leucocytozoon).This macro-ecological analysis will add to our understanding of host traits that influence the probability of avian haemosporidian infection and will help inform risk of emerging diseases.

Expert consensus on One Health for establishing an enhanced and integrated surveillance system for key infectious diseases

China has been continuously improving its monitoring methods and strategies to address key infectious diseases(KIDs).After the severe acute respiratory syndrome epidemic in 2003,China established a comprehensive report-ing system for infectious diseases(IDs)and public health emergencies.The relatively lagging warning thresholds,limited warning information,and outdated warning technology are insufficient to meet the needs of comprehensive monitoring for modern KIDs.Strengthening early monitoring and warning capabilities to enhance the public health system has become a top priority,with increasing demand for early warning thresholds,information,and tech-niques,thanks to constant innovation and development in molecular biology,bioinformatics,artificial intelligence,and other identification and analysis technologies.A panel of 31 experts has recommended a fourth-generation comprehensive surveillance system targeting KIDs(41 notifiable diseases and emerging IDs).The aim of this surveil-lance system is to systematically monitor the epidemiology and causal pathogens of KIDs in hosts such as humans,animals,and vectors,along with associated environmental pathogens.By integrating factors influencing epidemic spread and risk assessment,the surveillance system can serve to detect,predict,and provide early warnings for the occurrence,development,variation,and spread of known or novel KIDs.Moreover,we recommend comprehensive ID monitoring based on the fourth-generation surveillance system,along with a data-integrated monitoring and early warning platform and a consortium pathogen detection technology system.This series of considerations is based on systematic and comprehensive monitoring across multiple sectors,dimensions,factors,and pathogens that is sup-ported by data integration and connectivity.This expert consensus will provides an opportunity for collaboration in various fields and relies on interdisciplinary application to enhance comprehensive monitoring,prediction,and early warning capabilities for the next generation of ID surveillance.This expert consensus will serve as a reference for ID prevention and control as well as other related activities.

Surveillance and response strategies for zoonotic diseases:a comprehensive review

Out of all emerging infectious diseases, approximately 75% are of zoonotic origin, with their source often traced back to animals. The emergence of zoonoses is driven by a complex interplay between anthropogenic, genetic, ecological, socioeconomic, and climatic factors. This intricate web of influences poses significant challenges for the prediction and prevention of zoonotic outbreaks. Effective coordination and collaboration among the animal, human, and environmental health sectors are essential for proactively addressing major zoonotic diseases. Despite advancements in surveillance and diagnostic practices, the emergence of zoonoses continues to be a pressing global concern. Therefore, prioritizing zoonotic disease surveillance is of paramount importance as part of a comprehensive disease prevention and containment strategy. Furthermore, evaluating existing surveillance systems provides insights into the challenges faced, which can be mitigated through implementation of One Health principles involving relevant stakeholders. To initiate multisectoral partnerships, it is crucial to identify the priorities and core themes of surveillance systems with equitable inputs from various sectors. Strengthening surveillance, promoting data sharing, enhancing laboratory testing capabilities, and fostering joint outbreak responses in both the human and animal health sectors will establish the necessary infrastructure to effectively prevent, predict, detect, and respond to emerging health threats, thereby reinforcing global health security. This review assesses existing surveillance approaches by offering an overview of global agencies engaged in monitoring zoonoses and outlines the essential components required at the human–animal–environment interface for designing comprehensive surveillance networks. Additionally, it discusses the key steps necessary for executing effective zoonotic disease surveillance through a One Health approach, while highlighting the key challenges encountered in establishing such a robust surveillance system.

Landscape of emerging and re-emerging infectious diseases in China： impact of ecology, climate, and behavior

For the past several decades, the infectious disease profile in China has been shifting with rapid developments in social and economic aspects, environment, quality of food, water, housing, and public health infrastructure. Notably, 5 notifiable infectious diseases have been almost eradicated, and the incidence of 18 additional notifiable infectious diseases has been significantly reduced. Unexpectedly, the incidence of over 10 notifiable infectious diseases, including HIV, brucellosis, syphilis, and dengue fever, has been increasing. Nevertheless, frequent infectious disease outbreaks/events have been reported almost every year, and imported infectious diseases have increased since 2015. New pathogens and over 100 new genotypes or serotypes of known pathogens have been identified. Some infectious diseases seem to be exacerbated by various factors, including rapid urbanization, large numbers of migrant workers, changes in climate, ecology, and policies, such as returning farmland to forests. This review summarizes the current experiences and lessons from China in managing emerging and re-emerging infectious diseases, especially the effects of ecology, climate, and behavior, which should have merits in helping other countries to control and prevent infectious diseases.

Need of surveillance response systems to combat Ebola outbreaks and other emerging infectious diseases in African countries

There is growing concern in Sub-Saharan Africa about the spread of the Ebola virus disease(EVD),formerly known as Ebola haemorrhagic fever,and the public health burden that it ensues.Since 1976,there have been 885,343 suspected and laboratory confirmed cases of EVD and the disease has claimed 2,512 cases and 932 fatality in West Africa.There are certain requirements that must be met when responding to EVD outbreaks and this process could incur certain challenges.For the purposes of this paper,five have been identified:(i)the deficiency in the development and implementation of surveillance response systems against Ebola and others infectious disease outbreaks in Africa;(ii)the lack of education and knowledge resulting in an EVD outbreak triggering panic,anxiety,psychosocial trauma,isolation and dignity impounding,stigmatisation,community ostracism and resistance to associated socio-ecological and public health consequences;(iii)limited financial resources,human technical capacity and weak community and national health system operational plans for prevention and control responses,practices and management;(iv)inadequate leadership and coordination;and(v)the lack of development of new strategies,tools and approaches,such as improved diagnostics and novel therapies including vaccines which can assist in preventing,controlling and containing Ebola outbreaks as well as the spread of the disease.Hence,there is an urgent need to develop and implement an active early warning alert and surveillance response system for outbreak response and control of emerging infectious diseases.Understanding the unending risks of transmission dynamics and resurgence is essential in implementing rapid effective response interventions tailored to specific local settings and contexts.Therefore,the following actions are recommended:(i)national and regional inter-sectorial and trans-disciplinary surveillance response systems that include early warnings,as well as critical human resources development,must be quickly adopted by allied ministries and organisations in African countries in epidemic and pandemic responses;(ii)harnessing all stakeholders commitment and advocacy in sustained funding,collaboration,communication and networking including community participation to enhance a coordinated responses,as well as tracking and prompt case management to combat challenges;(iii)more research and development in new drug discovery and vaccines;and(iv)understanding the involvement of global health to promote the establishment of public health surveillance response systems with functions of early warning,as well as monitoring and evaluation in upholding research-action programmes and innovative interventions.
