This systematic review aims to map and synthesize existing evidence on RSV epidemiology and genotypic distribution across the FSU. Published studies from eLIBRARY and PubMed databases queried for RSV prevalence data, together with public health surveillance datasets, were used to summarize RSV prevalence research across eight FSU countries. Random-effects meta-analysis across age strata showed high prevalence in children before 6 (21%) and a progressive decline with age, which is in agreement with global data. Prevalence estimates showed a high degree of variability partially explained by study scope and clinical presentation. We observed COVID-19-related seasonal disruptions of RSV seasonality, followed by gradual post-pandemic stabilization. Genotypic data reflects global trends with two cosmopolitan clades, A.D and B.D, and their descendants, dominating in the region. The review is limited by uneven geographical and temporal coverage, and scarce data on adults. The review provides the first integrated summary of RSV epidemiology across the FSU and underscores the need for expanded regional surveillance and genomic reporting.<\/jats:p>","DOI":"10.3390\/v18010126","type":"journal-article","created":{"date-parts":[[2026,1,19]],"date-time":"2026-01-19T11:35:27Z","timestamp":1768822527000},"page":"126","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Respiratory Syncytial Virus Prevalence and Genotypic Distribution in the Countries of the Former Soviet Union: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2806-5933","authenticated-orcid":false,"given":"Denis E.","family":"Maslov","sequence":"first","affiliation":[{"name":"Faculty of Natural Sciences, Novosibirsk State University, Pirogov 2, Novosibirsk 630090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3797-7731","authenticated-orcid":false,"given":"Ivan D.","family":"Osipov","sequence":"additional","affiliation":[{"name":"Faculty of Natural Sciences, Novosibirsk State University, Pirogov 2, Novosibirsk 630090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7293-6815","authenticated-orcid":false,"given":"Daria S.","family":"Zabelina","sequence":"additional","affiliation":[{"name":"Faculty of Natural Sciences, Novosibirsk State University, Pirogov 2, Novosibirsk 630090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9983-9939","authenticated-orcid":false,"given":"Anastasia A.","family":"Pak","sequence":"additional","affiliation":[{"name":"Faculty of Natural Sciences, Novosibirsk State University, Pirogov 2, Novosibirsk 630090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7786-2464","authenticated-orcid":false,"given":"Sergey V.","family":"Netesov","sequence":"additional","affiliation":[{"name":"Faculty of Natural Sciences, Novosibirsk State University, Pirogov 2, Novosibirsk 630090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"281","DOI":"10.1093\/oxfordjournals.aje.a119901","article-title":"Recovery From Infants With Respiratory Illness of a Virus Related to Chimpanzee Coryza Agent (CCA)","volume":"66","author":"Chanock","year":"1957","journal-title":"Am.
