A comprehensive meta-analysis is necessary to assess the current status of the global H9 outbreak. In this research, a literature review and meta-analysis are presented on the surveillance studies of the H9 subtype of avian influenza in wild birds worldwide up to 2024. <b><i>Methods:</i></b> A comprehensive search strategy was employed, utilizing the China Science and Technology Journal Database, China National Knowledge Infrastructure, PubMed, Google Scholar, and Scientific Direct databases. The exclusion criteria for this study included duplicate studies, reviews, other host studies, as well as research with inconsistent or insufficient data. An analysis was conducted on data obtained from a total of 31 publications. The rate-conversion analyses were conducted using a random-effects model in the \"meta\" package of the \"R\" software, with the PFT method implemented. <b><i>Results:</i></b> In the meta-analysis, the prevalence of wild bird H9 avian influenza virus (AIV) was found to be 0.02% (193 out of 365,972). Statistically significant higher prevalences of wild bird influenza A virus were observed in Norway and South Africa (0.87%, 21/2417 and 0.44%, 10/1155, respectively) in comparison with other regions. Within the <i>Anseriformes</i> family, the prevalence rate was much greater (0.17%, 80 out of 90,014) compared with other species. In addition, we performed subgroup analyses that included geographical variables. These assessments showed a higher prevalence of H9 in wild birds in cold regions (0.08%, 30/100,691). <b><i>Conclusion:</i></b> In summary, our results suggest that the occurrence of H9 AIV in avian populations differs among different geographical areas and species. Therefore, it is necessary to conduct further surveillance on the prevalence of AIV in wild birds to guide the creation of strong and efficient regulatory strategies targeted at eradicating the transmission of AIV across different species.</p>","PeriodicalId":23683,"journal":{"name":"Vector borne and zoonotic diseases","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143812510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Viral shedding from bats is an essential prerequisite to bat-to-human viral transmission and understanding the timing and intensity of viral shedding from bats is critical to mitigate spillover risks.

We conducted a comprehensive review of longitudinal studies on bat viruses with spillover potential to synthesize patterns of seasonal viral shedding and explore associated risk factors. <b><i>Methods:</i></b> We extracted data from 60 reviewed articles and obtained 1085 longitudinal sampling events.

However, the southwestern U.S. presents particular challenges due to diverse tick fauna and varied ecologies. <b><i>Methods:</i></b> From 2021 to 2022, we conducted a partner-based tick surveillance program in Arizona and California to assess the presence of <i>Rickettsia</i> spp. pathogens and species composition of tick vectors. <b><i>Results:</i></b> A total of 913 ticks was collected, comprising in descending abundance <i>Rhipicephalus sanguineus</i>, <i>Dermacentor similis</i>, <i>Ixodes pacificus (I. pacificus)</i>, <i>Argas sp</i>., <i>Otobius megnini,</i> and <i>Haemaphysalis leporispalustris</i>. Arizona submitted predominantly brown dog ticks (90.05% of all ticks from Arizona), while California showed greater tick species richness with five species identified. No <i>Rickettsia rickettsii</i> was detected, but a variety of other <i>Rickettsia</i> spp. was found in ticks from both Arizona and California and included <i>Rickettsia rhipicephali (R. rhipicephali)</i>, Rickettsia <i>massiliae</i>, and <i>Rickettsia monacensis</i>-like rickettsial agents of <i>I. pacificus</i>, and two rickettsial organisms that were not identified to species: one <i>Rickettsia montanensis</i> or <i>Rickettsia raoultii</i>-like, and the other most similar to <i>Candidatus Rickettsia tarasevichiae (R.</i> tarasevichiae). <b><i>Conclusion:</i></b> This research contributes to our understanding of tickborne diseases in the southwestern U.S., and emphasizes the need for targeted surveillance and intervention initiatives in a region with complex relationships among ticks, hosts, and <i>Rickettsia</i> species. In particular, the finding of an apparently novel pairing of an unknown <i>Argas</i> sp. tick and <i>R. tarasevichiae</i>-like organism suggests that argasid species are an important target for future research. In addition, the results-both tick species submitted and resulting <i>Rickettsia</i> spp. identified-highlights the strengths and potential biases associated with a partner-based sampling method for tick surveillance.</p>","PeriodicalId":23683,"journal":{"name":"Vector borne and zoonotic diseases","volume":" ","pages":"240-249"},"PeriodicalIF":1.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143558195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
