{"doi":"10.3390/pathogens13060488","title":"Expanding Understanding of Urban Rift Valley Fever Risk and Associated Vector Ecology at Slaughterhouses in Kisumu, Kenya","abstract":"Rift Valley fever virus (RVFV) is an adaptable arbovirus that can be transmitted by a wide variety of arthropods. Widespread urban transmission of RVFV has not yet occurred, but peri-urban outbreaks of RVFV have recently been documented in East Africa. We previously reported low-level exposure in urban communities and highlighted the risk of introduction via live animal influx. We deployed a slaughtered animal testing framework in response to an early warning system at two urban slaughterhouses and tested animals entering the meat value chain for anti-RVFV IgG and IgM antibodies. We simultaneously trapped mosquitoes for RVFV and bloodmeal testing. Out of 923 animals tested, an 8.5% IgG seroprevalence was identified but no evidence of recent livestock exposure was detected. Mosquito species abundance varied greatly by slaughterhouse site, which explained 52% of the variance in blood meals. We captured many Culex spp., a known RVFV amplifying vector, at one of the sites (p < 0.001), and this species had the most diverse blood meals. No mosquito pools tested positive for RVFV antigen using a rapid VecTOR test. These results expand understanding of potential RVF urban disease ecology, and highlight that slaughterhouses are key locations for future surveillance, modelling, and monitoring efforts.","journal":"Pathogens","year":2024,"id":468226,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9521,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1156835,"name":"Kevin Owuor","orcid":"0000-0003-0712-3209","position":1,"is_corresponding":false},{"id":351773,"name":"Bryson Ndenga","orcid":"0000-0002-8445-2885","position":2,"is_corresponding":false},{"id":1301027,"name":"Sammy Wambua","orcid":"0000-0002-3041-2714","position":3,"is_corresponding":false},{"id":1301393,"name":"Christabel Achieng Winter","orcid":null,"position":4,"is_corresponding":false},{"id":1301394,"name":"Salome Chemutai","orcid":null,"position":5,"is_corresponding":false},{"id":1301395,"name":"Rodney Omukuti","orcid":null,"position":6,"is_corresponding":false},{"id":1301396,"name":"Daniel Arabu","orcid":null,"position":7,"is_corresponding":false},{"id":1301397,"name":"Irene Miring’u","orcid":null,"position":8,"is_corresponding":false},{"id":553537,"name":"William C.
