This led to synchronous epidemics across the region associated mainly with the Asian lineage, which eventually subsided. Resurgent outbreaks have been recorded since, principally in South America, largely driven by the East-Central-South-African (ECSA) lineage. In 2025, more than 300,000 CHIKV suspected cases were reported in Brazil and Cuba.\n                      <\/jats:p>\n                    <\/jats:sec>\n                    <jats:sec>\n                      <jats:title>Case Summary<\/jats:title>\n                      <jats:p>In November 2025, a healthy adult male traveling from Cuba arrived in Merida, Mexico, and shortly after presented febrile symptoms consistent with an arboviral infection. CHIKV infection was diagnosed by RT-qPCR. Though the infection was mild, the patient developed a rash on the abdomen and neck that persisted for up to a month, with further inflammation of the joints of the left leg. Phylogenetic analysis of the viral genome indicated placement within the ECSA lineage, clustering with other contemporaneous virus genomes sampled from Brazil that belong to a recently described clade II within the country, in which viral genomes from Cuba also cluster.<\/jats:p>\n                    <\/jats:sec>\n                    <jats:sec>\n                      <jats:title>Conclusion<\/jats:title>\n                      <jats:p>We identify a travel-associated ECSA lineage CHIKV case in Mexico. This viral lineage has not previously been detected in the country. This finding highlights the risk for subsequent local transmission and is consistent with reports of the presence of this lineage in Cuba. Ten years since the last CHIKV epidemic in Mexico, strengthened surveillance is required to anticipate potential local outbreaks within the region.<\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1128\/asmcr.00035-26","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T13:00:09Z","timestamp":1784638809000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Detection and genomic characterization of a travel-associated ECSA lineage chikungunya virus infection in Mexico"],"prefix":"10.1128","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-5792-6960","authenticated-orcid":true,"given":"Daniel","family":"Canul Canul","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/032p1n739","id-type":"ROR","asserted-by":"publisher"}],"name":"Universidad Aut\u00f3noma de Yucat\u00e1n, Centro de Investigaciones Regionales Dr. Hideyo Noguchi","place":["Merida, Mexico"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7161-541X","authenticated-orcid":true,"given":"K.
