This desk review synthesized 60 years of data (1957\u20132025) using a structured, multidatabase search across four domains: disease, genotype\/lineage, geographic spread, and temporal context. Data were stratified into three periods: Period I (1957\u20131980), Period II (1981\u20132000), and Period III (2001\u20132025). Results indicate that Period I saw the identification of serotypes O, A, and C, though serotype C has not been detected after 1983. Period II was marked by the continued circulation of serotypes O and A, and the first emergence of Serotype SAT 2 near the Kenya\u2013Ethiopia border, which temporarily disappeared until its major re\u2010emergence in 2007. Period III is characterized by a significant intensification and modernization of FMD virus (FMDV) outbreak investigation that provided more granular data on viral activity in the country. The period saw four major endemic serotypes O, A, SAT 2, and SAT 1, SAT one being confirmed for the first time during this period, circulate simultaneously and covering the entire country. Molecular analyses revealed a heterogeneous landscape: serotype O is dominated the serotype distribution in the country by its O\/EA\u20103 and O\/EA\u20104 topotypes, while serotype A involving complex lineages (Africa G\u2010I, G\u2010IV, and G\u2010VII) follows in serotype O and precedes serotype SAT 2 in distribution. Notably, serotype SAT 2 has historically comprised four topotypes (IV, VII, XIII, and XIV), with the recent dominance of the re\u2010emergent SAT 2\/XIV topotype. The global biosecurity threat posed by FMDV SAT 2 topotype XIV stems from its unprecedented transcontinental dissemination into immunologically naive regions, rather than inherent lethality. This expansion highlights the complex evolutionary dynamics of the virus and the vulnerability of current surveillance system. The global dissemination of emerging lineages, such as SAT 2 topotype XIV, underscores the complex evolutionary dynamics and environmental plasticity inherent across all FMDV serotypes. The rapid shift of these viruses into nonendemic territories highlights critical vulnerabilities in existing biosecurity. Ultimately, these dynamics necessitate a shift toward adaptive, multiserotype surveillance and integrated control frameworks to address the continuous antigenic evolution and geographical expansion of the virus. Advancing Ethiopia along the progressive control pathway (PCP\u2010FMD) is critically contingent upon evaluating the protective efficacy of current trivalent vaccines against rapidly evolving field strains. Immediate intervention is required to address diverged genotypes that jeopardize both national herd health and international market access.<\/jats:p>","DOI":"10.1155\/tbed\/6349383","type":"journal-article","created":{"date-parts":[[2026,9,26]],"date-time":"2026-09-26T12:24:57Z","timestamp":1790425497000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evolutionary and Spatiotemporal Dynamics of Foot\u2010and\u2010Mouth Disease Virus in Ethiopia (1957\u20132025): A Molecular Perspective on Serotype Persistence and Emergence"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1792-9954","authenticated-orcid":false,"given":"Daniel","family":"Gizaw","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1949-5317","authenticated-orcid":false,"given":"Fentahun","family":"Wondmnew","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9846-0301","authenticated-orcid":false,"given":"Fasil","family":"Aklilu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7605-5433","authenticated-orcid":false,"given":"Getnet Abie","family":"Mokonnen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Henning","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Berhanu","family":"Admasu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Badi","family":"Maulidi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wudu","family":"Temesgen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jef.","family":"Hammond","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,26]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"crossref","first-page":"1079","DOI":"10.1111\/tbed.12507","article-title":"Foot-and-Mouth Disease Impact on Smallholders\u2014What Do We Know, What Don\u2019t We Know and How Can We Find Out More?","volume":"64","author":"Knight-Jones T.
