ABSTRACT
Many zoonotic diseases are found in wild animals and present a serious risk to human health, in particularly the virus carried by birds flying freely around the world is hard to control. There are three main bird migration routes which cover the most areas of China. It is important to investigate and fully understand the types of avian transmitted diseases in key areas on the bird migration routines and its impacts on both birds and human health. However, no literature is available in how about the risk of virus carried by migrating birds, and how to predict and reduce this risk of virus spreading to human being so far. In this paper, we first reviewed the main pathogen types carried by birds, including coronaviruses, influenza viruses, parasites, Newcastle disease virus (NDV), etc., and then discussed the spread risk of avian viruses to human being and animals in key areas of biosafety prevention. We also analyzed and discussed the risk of cross-spread of diseases among different bird species in nature reserves located on bird migration routes which provide sufficient food sources for migratory birds and attract numerous birds. Diseases transmitted by wild birds pose a serious threat to poultry farms, where high density of poultry may become avian influenza virus (AIV) reservoirs, cause a risk of avian influenza outbreaks. Airports are mostly built in suburban areas or remote areas with good ecological environment. There are important transit places for bird migration and densely populated areas, which have serious risk of disease transmission. Finally, this paper puts forward the following prevention suggestions from three aspects. First, establish and improve the monitoring and prediction mechanism of migratory birds, and use laser technology to prevent contact between wild birds and poultry. Second, examine and identify virus types carried by birds in their habitats and carry out vaccination. Third, protect the ecological environment of bird habitat, and keep wild birds in their natural habitat, so as to reduce the contact between wild birds and human and poultry, and thus reduce the risk of virus transmission.
ABSTRACT
Housing quality and affordability are well established as social determinants of health through direct and indirect mechanisms. Respiratory illnesses related to housing are nearly all the result of housing disrepair that allows intrusion into the home of environmental agents that are directly or indirectly associated with disease. Structural deficiencies such as leaks, cracks in the foundation or holes in the home's exterior can facilitate the presence of mould, which is causally linked to the development of asthma and is associated with exacerbation of asthma symptoms in children and adults. Indoor cleanliness can also contribute to the presence of mice and cockroaches. Proper ventilation can improve air quality, reducing exposure to PM, VOCs and infectious respiratory agents. Disparities in exposure to the housing conditions associated with respiratory disease are readily apparent across socioeconomic lines. Low-income families are less likely to be able to afford the costs of maintaining a home, which prevents them from making repairs that could improve respiratory health.Copyright © ERS 2023.
ABSTRACT
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from wildlife has raised concerns about spillover from humans to animals, the establishment of novel wildlife reservoirs, and the potential for future outbreaks caused by variants of wildlife origin. Norway rats (Rattus norvegicus) are abundant in urban areas and live in close proximity to humans, providing the opportunity for spillover of SARS-CoV-2. Evidence of SARS-CoV-2 infection and exposure has been reported in Norway rats. We investigated SARS-CoV-2 infection and exposure in Norway rats from Southern Ontario, Canada. From October 2019 to June 2021, 224 rats were submitted by collaborating pest control companies. The majority of samples were collected in Windsor (79.9%;n = 179), Hamilton (13.8%;n = 31), and the Greater Toronto Area (5.8%;n = 13). Overall, 50.0% (n = 112) were female and most rats were sexually mature (55.8%;n = 125). Notably, 202 samples were collected prior to the emergence of variants of concern (VOC) and 22 were collected while the Alpha variant (B.1.1.7) was the predominant circulating VOC in humans. Nasal turbinate (n = 164) and small intestinal (n = 213) tissue samples were analyzed for SARS-CoV-2 RNA by RT-PCR. Thoracic cavity fluid samples (n = 213) were tested for neutralizing antibodies using a surrogate virus neutralization test (sVNT) (GenScript cPass);confirmatory plaque reduction neutralization test (PRNT) was conducted on presumptive positive samples. We did not detect SARS-CoV-2 RNA in any samples tested. Two out of eleven samples positive on sVNT had neutralizing antibodies confirmed positive by PRNT (1 : 40 and 1 : 320 PRNT70);both were collected prior to the emergence of VOC. It is imperative that efforts to control and monitor SARS-CoV-2 include surveillance of rats and other relevant wildlife species as novel variants continue to emerge.
ABSTRACT
The COVID-19 pandemic has highlighted the importance of incorporating nature-based solutions in urban design, in order to create sustainable and resilient cities. Inspired by these events, the present study aims at exploring the mental health benefits of nature exposure during the outbreak. Secondarily, we investigate changes in use patterns towards urban green spaces (UGS) and urban blue spaces (UBS) and whether extreme conditions, such as these of a lockdown, can lead to an increase in people's appreciation of urban nature. Through an online survey, we observed that the pandemic resulted in a decrease in the frequency of visitation to UGS/UBS (p < 0.001). Significant differences were found for exercise (p < 0.001) and socialization (p < 0.05) as main drivers for visiting urban nature pre- and post-lockdown. Accordingly, visitation rates for forests (p < 0.05), playgrounds (p < 0.001), and the sea (p < 0.001) differed significantly when comparing the two periods. In people's perception, UGS/UBS are important for the urban fabric (89%). Our structural equation model indicated that nature exposure had a beneficial effect on participants' mental health (p < 0.001). Pathways that explain the relationship between nature exposure and post- lockdown value were nature relatedness, motivation, and perceived importance of UGS/UBS. No mediation could be extracted for nature exposure and mental health. Our findings show the positive association between nature exposure and mental health improvement, especially in times of crisis, as well as a shift in the "value domain” towards urban nature.
ABSTRACT
The world has witnessed the largest single disruption to social wellbeing since the first known case of coronavirus disease 2019 (COVID-19) was reported in China in December 2019. In Malaysia, the government implemented the Movement Control Order (MCO) on 18 March 2020 in response to the COVID-19 pandemic. Thus, this paper highlights how the Malaysian government responded to COVID-19 in comparison with some Asian countries; and what has and has not worked for the MCO imposed by the government. The paper adopts a review approach that is supported by findings from both grey and academic literature. The findings reveal that the COVID-19 pandemic has significant impacts on the society's wellbeing in Malaysia, the most severe of which are negative mental health and job unemployment. On the other hand, COVID-19 has sparked a surge of volunteering in society. This paper presumably and hopefully represents a frontier review with more empirical research to be conducted to investigate the extent of the social impact of COVID-19, the outcomes of which are a call for re-envisioning of social policies in Malaysia. To the best knowledge of the authors, little empirical research has been conducted to explore the social-wellbeing implications of COVID-19 in Malaysia. By reflecting on the various scenarios-both detrimental and beneficial in the context of the COVID-19 pandemic, the paper identifies potential avenues for relevant research in the social wellbeing realm.
ABSTRACT
Coinfection caused by bacteria, parasites, or viruses complicates almost all feline panleukopenia virus (FPV) infections. Pathogens that colonize the gastrointestinal tract, Clostridium perfingens, Clostridium piliforme, Cryptosporidium spp, Giardia spp, Tritrichomonas fetus, canine parvovirus type 2,Salmonella sp., feline coronavirus, feline bocavirus, and feline astrovirus were isolated in the presence of FPV infection. Complex mechanisms between viruses, bacteria, protozoa, and hosts contribute to the pathogenesis and severity of coinfection. Prompt and accurate diagnosis, vaccination precautions, and appropriate treatment play important roles in reducing morbidity and mortality. This article outlines the etiology, pathogenesis, diagnosis, prevention, and treatment that can help veterinarians and pet owners improve their knowledge of managing the diseases.
ABSTRACT
This annual report summarizes the results of the 2021-2022 National Fruit Fly Surveillance Programme (NFFSP) in New Zealand. The report shows that despite the challenges posed by the Covid-19 pandemic, the programme was successful in meeting its objectives. A total of 139 individual trap runs were used to service the 7878 Lynfield traps in use, with no new traps established but several relocated to improve coverage. From the 2587 trap-run submissions, a total of 8183 vials were submitted, and no exotic fruit flies were detected. Thirteen samples collected in fruit-fly traps were categorized as "specimens of interest," while 9 specimens were submitted by trappers as passive surveillance samples. All lure batches tested during the season met the required standard, and field checks were made to ensure that all lures sent to trappers had been calibrated within the last 12 months. The report concludes that the trapping network was effective in supporting New Zealand's claims of area freedom.
ABSTRACT
Background: Coronavirus disease 2019 (COVID-19) is a rapidly spreading global emergency, causing significant damage to the global economy and health care. Knowledge and awareness are crucial elements in stimulating self-imposed preventive measures. Objectives: We evaluated the knowledge and awareness about COVID-19 and the practice of hygiene measures to prevent the spread of coronavirus disease. Methods: A prospective observational study was conducted in Karachi, Pakistan, between March 01 and March 25, 2020, using a non-probability consecutive sampling technique. All individuals aged 18 years or above were included in the study. The individuals who had no formal education were excluded from the study. A self-reported questionnaire assessing knowledge, awareness, and practices was distributed among the participants. Results: The mean age +or- SD of the study population was 29.11 +or- 7.8 years. In our study, 424 (98.6%) participants knew that a virus causes COVID-19, and most were knowledgeable about the disease's transmission mode. Higher education status and the medical profession were associated with the better practice of preventive measures. Conclusions: We recommend that knowledge about COVID-19 and preventive measures be spread across the country via electronic media.
ABSTRACT
The exposure patterns of pest control and disinfection workers have changed after the coronavirus disease 2019 (COVID-19) outbreak, but the health risks of chemical exposure have not been assessed. We identified these workers' chemical exposure patterns and risks before and after the COVID-19 outbreak. We used data conducted between 2018 (pre-pandemic) and 2021 (post-pandemic) from three-year cross-sectional surveys on pest control and disinfection workers. Inhalation and dermal exposure concentrations were estimated using equations based on a biocidal product risk assessment model from the Korean National Institute of Environmental Research. The non-carcinogenic and carcinogenic risks of chemicals were calculated using the United States Environmental Protection Agency risk assessment model. We found that the annual work frequency (50th percentile) of foggers using disinfectants increased the most among all the work types, from 140 uses/year to 176 uses/year after the COVID-19 outbreak. Moreover, all chemicals' non-carcinogenic and carcinogenic risks increased regardless of exposure routes. In the worst scenario (95th percentile), the margin of exposure for citric acid, benzethonium chloride, benzyl-C12-16-alkyldimethyl chlorides, and sodium chlorite of inhalation exposure, and isopropyl alcohol and benzyl-C12-16-alkyldimethyl chlorides of dermal exposure were acceptable (>100) before the COVID-19 outbreak but became unacceptable (<100) after the COVID-19 outbreak. Carcinogenic risks of dichlorvos from inhalation and dermal exposure were above acceptable levels (>10−6) before and after the COVID-19 outbreak but comparatively high after the COVID-19 outbreak. Additionally, significantly more workers experienced health symptoms after the COVID-19 outbreak (p<0.05), with the most common being muscle lethargy (31%), skin/face stinging (28.7%), and breath shortness/neck pain (24.1%).

ABSTRACT
Drawing on a synthesis of the recent empirical literature, we show that since its first report in 2016, fall armyworm has continued to spread rapidly posing severe threats to the food security of smallholders in Sub-Saharan Africa. Fall armyworm impacts have been more pronounced during 2020 due to Coronavirus Disease-2019 (COVID-19) restrictions that hampered labor availability and smallholder access to crop protection inputs. The agricultural system's vulnerability to COVID-19 underscores the need for a recovery effort that focuses on building back better for smallholder communities to overcome the impacts of the pandemic, and build resilience against similar threats in the future. Institutional strengthening, linkages to input and output markets, and microcredit support will address immediate production challenges in the wake of COVID-19. Enhancing the technical capacities of smallholders and regional collaboration for multirisk monitoring and early warning will inform coordinated actions for the sustainable management of fall armyworm and other emerging risks. © 2023 The Author(s)
ABSTRACT
This report describes the impact of the SARS-CoV-2 pandemic on the productive and economic aspects of livestock and aquaculture production in Italy, including farm management, labour, income, marketing and consumption of animal products (meat, fish, eggs, milk and dairy products), consumer behaviour, food safety, agrotourism and disease control.
ABSTRACT
The possession of exotic animals as pets is a social practice that has become more visible in Mexico in recent years, so it is interesting to understand its environmental and social implications and those related to human health. The present study aims to identify the main species of exotic animals kept as pets and the zoonotic diseases reported in these species. We analyzed official figures of seizures of exotic fauna in Mexico and reviewed specialized literature on zoonotic diseases documented in Mexico in these species. We identified zoonoses in species of fauna that can be acquired legally and illegally in the country, reported in environments in which animals coexist with other species and are in direct contact with people, which represents an important factor in the spread and propensity of this type of disease. We conclude that the sanitary regulation of wildlife markets, the monitoring and studying microorganisms associated with wildlife are valuable strategies to prevent the emergence of zoonoses.
ABSTRACT
It is reported that networks developed through the ACIAR Pacific Plant Biosecurity Partnership programme continue to help strengthen capacity in the prevention of the spread of pests and disease in crops throughout the Pacific region, despite COVID-19 disrupting the programme. Participants from 9 Pacific countries have developed their skills, networks and capacity to facilitate trade and prevent the spread of disease. Relationships and resources created through the programme continue to provide support for information-sharing around plant pests and diseases.
ABSTRACT
SARS-CoV-2 was first identified in humans in December 2019 and has since affected almost 68 million people causing over 1.5 million deaths worldwide. Animal-to-human and animal-to-animal transmission has been documented within farmed minks in several countries. SARS-CoV-2 has been identified in a farmed mink population in a number of countries. Some of the affected farms reported also workers SARS-CoV-2 infection and it is hypothesized that the mink farms were infected through human-mink transmission proving SARS-CoV-2 capability of reverse zoonosis. This Tripartite Risk Assessment, as a joint effort under the GLEWS+ initiative, completed with the Food and Agriculture Organization (FAO), the World Health Organization (WHO), and the World Organisation for Animal Health (OIE), evaluates the risk of introduction and spread of SARS-CoV-2 within fur farming systems as well as whether farmed fur animals could play a significant role in the spread of SARS-CoV-2 to humans via spillover. Additionally, using a One Health approach, the Tripartite evaluated the risk of the escaped minks leading to the establishment of a viral reservoir in susceptible wildlife populations. This work provides guidance to Members on this newly emerging threat.
ABSTRACT
This Annual Report provides in-depth information, key facts and figures from the global plant health community of the International Plant Protection Convention (IPPC) during the International Year of Plant Health (IYPH) 2020. The report highlights the efforts of the IPPC in promoting and implementing plant protection measures, including the development and implementation of international standards for phytosanitary measures (ISPMs), which are guidelines for countries to follow in order to prevent the spread of plant pests. The report also discusses the challenges faced by the IPPC in the face of the COVID-19 pandemic, including the need to ensure the continuity of essential plant protection activities while taking into account public health and safety measures. Overall, the report emphasizes the importance of plant protection in ensuring global food security, trade, and biodiversity conservation, and the need for continued collaboration and coordination among countries and stakeholders to achieve these goals.
ABSTRACT
Rodent pests can have major social, economic, and environmental impacts. Their management, therefore, represents a complex socio-ecological problem involving a network of stakeholders from across different sectors, with diverging and sometimes competing interests. Failure to incorporate stakeholder interests can result in ineffective or unsustainable management programmes, with unintended negative consequences for people and nature.Participatory approaches to decision-making have been proposed as suitable strategies to tackle complex problems, yet, these processes are often considered too difficult, costly, or time-consuming to implement.To facilitate a participatory approach to rodent control in Madagascar, we identified and mapped key stakeholders and developed a multisector framework for guiding rodent management programmes based on current literature and expert recommendations. We then carried out interviews and focus groups with stakeholders and end-users to validate the final framework.The final framework unifies stakeholder interests around the dimensions of People, Resources, Knowledge and Power. Combined application of the stakeholder map and framework provides decision-makers with the tools to identify stakeholder interests;to explore areas of conflict, as well as areas of agreement;and to ensure that these are addressed within the design of control programmes. As an assessment tool, the framework can also be used to evaluate the responsiveness of programmes to the needs of different stakeholders and assess whether objectives are being reached.We recommend the application of the stakeholder map and framework to encourage and strengthen participatory approaches aimed at rodent pest control. Due to the inclusive and interdisciplinary nature of the framework, it can be applied to address numerous complex social, environmental, and economic issues across scales, sectors, and systems.Read the free Plain Language Summary for this article on the Journal blog.
