The virus has been shown to transmit among WTD, and across species in both directions (deer-to-humans and humans-to-deer). Cross-species transmission requires infectious contact between WTD and humans, the form and frequency of which is poorly understood. The aim of this cross-sectional survey was to understand the frequency and type of contact between the general public in the state of Illinois and WTD, and to identify human populations at highest risk for such contact. An online survey was distributed using convenience sampling from list serves, social media, and community partners or extension liaisons. Questions addressed frequency and distance of contact with WTD, encompassing live animals and bodily fluids. Standard and ordinal logistic regression were used to identify factors associated with contact. An overall risk score was calculated, and linear regression was used to identify factors associated with risk. We found that hunters and those who have deer feeding on their property are more likely to report contact with deer, and that people reporting a larger lot size and living in counties with higher proportions of potential deer habitat are more likely to report deer feeding on their property. These results will better identify people with a high likelihood of WTD contact for messaging and further research. Our survey did not distinguish between contact with live and dead WTD, thus the findings are most relevant to deer-to-human cross-species transmission than the human-to-deer direction.</p>","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":"147-160"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 1980s, researchers in the Amazon have reported recurrent local disappearances of WLP populations. Although such disappearances impact the species conservation and the food security of rural societies, no studies have drawn consistent conclusions about the causes of these population collapses. However, it has recently been proposed that the overabundance of this species before its decline would be related to infectious disease outbreaks. In the current study, we aimed to determine the circulation (occurrence and exposure) of viruses relevant to swine health in CP and WLP populations, namely classical swine fever virus (CSFV), Aujeszky's disease virus (ADV), swine vesicular disease virus (SVDV), and porcine circoviruses (PCV). The study was conducted in two areas of the northeastern Peruvian Amazon: the Yavarí-Mirín River basin (2008 -2020), where WLPs experienced extreme population fluctuations, and the Pucacuro National Reserve (2012-2014), where no WLP disappearances have been reported. Since WLP is not easily found during population declines, we also sampled CP as an indicator of virus circulation in the area as they are likely to be susceptible to the same pathogens. CSFV and ADV antibodies were detected in both peccary species and both areas. Diseases caused by CSFV and ADV have the potential to act as ultimate causes of population collapse, especially in large WLP populations where overabundance could increase the rate of pathogen transmission. Our results were inconclusive in establishing whether or not these viruses drove the WLP population to collapse, but their potential role warrants deeper investigation, expanding the geographical coverage of studies on infectious diseases in peccaries.</p>","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":"69-78"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11890321/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142973116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interactions between pastoralists and national parks, as well as the subsequent impacts, remain insufficiently understood in Afar. Two structured questionnaire surveys were conducted in 2021, including 300 pastoralist households in seven woredas of Afar, and 58 staff from three national parks (Awash, Alidegi and Yangudi Rassa).
