{"doi":"10.21149/13980","title":"Cocirculation and replacement of SARS-CoV-2 variants in crowded settings and marginalized populations along the US-Mexico border","abstract":"OBJECTIVE: To interrogate the circulating SARS-CoV-2 lin-eages and recombinant variants in persons living in migrant shelters and persons who inject drugs (PWID). MATERIALS AND METHODS: We combined data from two studies with marginalized populations (migrants in shelters and persons who inject drugs) in Tijuana, Mexico. SARS-CoV-2 variants were identified on nasal swabs specimens and compared to publicly available genomes sampled in Mexico and California. RESULTS: All but 2 of the 10 lineages identified were predomi-nantly detected in North and Central America. Discrepan-cies between migrants and PWID can be explained by the temporal emergence and short time span of most of these lineages in the region. CONCLUSION: The results illustrate the temporo-spatial structure for SARS-CoV-2 lineage dispersal and the potential co-circulation of multiple lineages in high-risk populations with close social contacts. These conditions create the potential for recombination to take place in the California-Baja California border.","journal":"Salud Pública de México","year":2022,"id":287936,"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":0.6603,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":308875,"name":"Ietza Bojórquez","orcid":"0000-0003-1723-7269","position":1,"is_corresponding":false},{"id":910314,"name":"Jaime Sepúlveda","orcid":"0000-0001-5687-6464","position":2,"is_corresponding":false},{"id":516177,"name":"Alicia Vera","orcid":"0000-0002-8708-8169","position":3,"is_corresponding":false},{"id":409490,"name":"Gudelia Rangel","orcid":"0000-0003-3376-152X","position":4,"is_corresponding":false},{"id":383131,"name":"Britt Skaathun","orcid":"0000-0001-8780-3612","position":5,"is_corresponding":false},{"id":300754,"name":"Sanjay R.
