Historical records evidenced of urban landscape changes, and environmental transitions brought by the improper growths and urban development’s of the urbanisation and industrialization in the developing countries, especially in India, significantly chaotic urban sprawl and industrial growths, and the development of its allied activities for the recent decades, invites new, emerging, re-emerging, and triggers the tropical infectious diseases including vector borne diseases (VBD) as well non-communicable diseases. Urban sprawl has a multiplier effect of growth of unplanned a crowded housing, and industrialization has an impact on the urban landscape with commercial and market development, and roads over large expanses of urban land while little concern for appropriate urban planning. The union government of India is launching to promote 100 mega smart city projects / metropolitan / urban agglomeration across the nation for betterment of the standard of living infrastructure facilities by 2030. The large scale urban landscape architectural changes, land use / land cover changes, environmental transitions, and micro climatic changes in the heart of the urban landscape, and its fringe areas on the consequence of built-up structures, construction of roads transport networks, drainages, commercial buildings, human dwellings, educational buildings, legal and medical health services, income tax professionals, small scale to large scale industries, etc., The census of India, reports highlighted that people mass movements / migration from rural to the urban, and small towns to mega cities are notably accelerating trends for the recent decades mainly for the purposes of occupation, education, trade and commerce, and professional services, generally reasons for male migration, and marriage is the absolute reason for female adults migration. The spatial and temporal aspects of malaria and dengue has been declining trends in rural settings, however, it has been accelerating trends in the urban settings due to the urban buoyant migrants. Urbanization and industrialization effect on urban landscape environment leads to breakdown of sanitations, water-borne diseases associated with inadequate  and unsafe drinking water supply, tendency to use metal, plastic, and mud pots water storage containers, discarded domestic waste misshapen to vector breeding habitats containers, urban heat island, garbage waste disposal, liquid waste from dwellings, and industries, air pollution (dust, pollen and spores suspended as particles, Sulphur Dioxide-SO2, nitrogen oxides-NO, Carbonate-CO3, depletion of Oxygen O2, Ozone-O3, Methane  Gas- CH₄, Lead- Pb,  Mercury- Hg etc.,), exonerated by the industries and urban transport emissions, modern transport / shipping goods and services, and collectively hazard to human health through erratic infectious diseases and vector borne diseases immediately.

Vector-borne diseases closely associated with the environment, such as leishmaniases, have been a usual argument about the deleterious impact of climate change on public health. From the biological point of view interaction of different variables has different and even conflicting effects on the survival of vectors and the probability transmission of pathogens. The results on ecoepidemiology of leishmaniasis in Argentina related to climate variables at different scales of space and time are presented. These studies showed that the changes in transmission due to change or increase in frequency and intensity of climatic instability were expressed through changes in the probability of vector-human reservoir effective contacts. These changes of contact in turn are modulated by both direct effects on the biology and ecology of the organisms involved, as by perceptions and changes in the behavior of the human communities at risk. Therefore, from the perspective of public health and state policy, and taking into account the current nonlinear increased velocity of climate change, we concluded that discussing the uncertainties of large-scale models will have lower impact than to develop-validate mitigation strategies to be operative at local level, and compatibles with sustainable development, conservation biodiversity, and respect for cultural diversity.

AbstractIn the era of emergence and re-emergence of vector-borne diseases, a high throughput trap-based insect monitoring is essential for the identification of invasive species, study of mosquito populations and risk assessment of disease outbreaks. Insect DNA metabarcoding technology has emerged as a highly promising methodology for unbiased and large-scale surveillance. Despite significant attempts to introduce DNA metabarcoding in mosquito or other insect surveillance qualitative and quantitative metabarcoding remains a challenge. In the present study, we have developed a methodology of in-tandem identification and quantification using cytochrome oxidase subunit I (COI) combined with a secondary multilocus identification and quantification involving three loci of 28S ribosomal DNA. The presented methodology was able to identify individual species in pools of mosquitoes with 95.94% accuracy and resolve with high accuracy (p = 1, χ2 = 2.55) mosquito population composition providing a technology capable of revolutionizing mosquito surveillance through metabarcoding. The methodology, given the respective dataset, has the potential to be applied to various small animal populations.

AbstractBackgroundVector-borne diseases remain major causes of human morbidity and mortality. It is increasingly recognized that the community of microbes inhabiting arthropods can strongly affect their vector competence, but the role of the tick microbiome in Borrelia transmission – the cause of Lyme disease – remains unclear.ResultsHere, we use a large-scale experiment to clarify the reciprocal interactions between Borrelia afzelii and the microbiome of Ixodes ricinus, its primary vector. In contrast to other reports, we find that depletion of the bacterial microbiome in larval ticks has no effect on their subsequent acquisition of B. afzelii during blood feeding on infected mice. Rather, exposure to B. afzelii-infected hosts drives pervasive changes to the tick microbiome, decreasing overall bacterial abundance, shifting bacterial community composition, and increasing bacterial diversity. These effects appear to be independent of the acquisition of B. afzelii by ticks, suggesting they are mediated by physiological or immunological aspects of B. afzelii infection in the rodent host.ConclusionsManipulation of the microbiome of I. ricinus larvae had no effect on their ability to acquire B. afzelii. In contrast, B. afzelii infection in the mouse had dramatic effects on the composition of the gut microbiome in I. ricinus nymphs. Our study demonstrates that vector-borne infections in the vertebrate host shape the microbiome of the arthropod vector.

Objectives. This scoping review aimed to support a landscape analysis to identify lessons learned about intersectoral collaborations (ISCs) by describing their existing models in the context of dengue, malaria and yellow fever. Methods. A scoping review following the methodology of Joanna Briggs Institute was performed using the following inclusion criteria: studies involving humans; studies discussing intersectoral collaborations, malaria/dengue/yellow fever, and prevention or control at any level; and studies in countries endemic for the aforementioned diseases. Studies were screened using Covidence, while data were extracted using NVivo. Results. Of the 7,535 records retrieved, 69 were included in the qualitative analysis. Most ISCs were initiated by multilateral organizations and ministries of health, and none by communities. Strategies included advocacy, health education, research, public health measures, resource mobilization, service delivery and training; mostly employed on a community level. Monitoring and evaluation were mostly formative, ongoing, and participatory. Gaps included administrative and policy barriers, resource shortages, and inadequate research and training. Conclusions. Multiple models of ISC exist in the literature. There is a need to develop a comprehensive framework for an effective and sustainable multisectoral approach for the prevention and control of VBDs ensuring adequate resources, active stakeholders, and strategies that span the entire socio-ecological spectrum.

Climate change is impacting human health and straining heavily burdened health services everywhere. Recognition of the linkages between climate change and health systems, such as shifts in vector-borne diseases and decreased access to services, is growing, yet many countries are still struggling both to mainstream, or integrate, climate adaptation into their health plans and to implement activities on the ground. This paper shares case studies from Fiji, Ghana, and Benin, three countries making progress with mainstreaming climate change adaptation into planning and implementation in health systems. The authors outline the enabling factors, challenges and lessons learned across these three countries, followed by recommendations to mainstream climate adaptation and build climate resilience in the health sector.

Purpose The SUpport PRogram (SUPR) study was carried out in the context of a private academic partnership and is the first study to evaluate the long-term effects of a communication program (SUPR) for older hearing aid users and their communication partners on a large scale in a hearing aid dispensing setting. The purpose of this research note is to reflect on the lessons that we learned during the different development, implementation, and evaluation phases of the SUPR project. Procedure This research note describes the procedures that were followed during the different phases of the SUPR project and provides a critical discussion to describe the strengths and weaknesses of the approach taken. Conclusion This research note might provide researchers and intervention developers with useful insights as to how aural rehabilitation interventions, such as the SUPR, can be developed by incorporating the needs of the different stakeholders, evaluated by using a robust research design (including a large sample size and a longer term follow-up assessment), and implemented widely by collaborating with a private partner (hearing aid dispensing practice chain).
