This study aimed to determine exposure to the Spotted Fever Group (SFG) and Typhus Group (TG) in human serum samples suspected of tick-borne diseases (TBD) between 2015 and 2022. A total of 620 samples were analysed using indirect immunofluorescence assay (IFA) to detect IgG antibodies against SFG (<jats:italic>Rickettsia rickettsii<\/jats:italic>) and TG (<jats:italic>Rickettsia typhi<\/jats:italic>), considering a titer of \u226564 as positive. Results showed that 103 samples (17%) were positive for <jats:italic>R. rickettsii<\/jats:italic> and 145 (24%) for <jats:italic>R. typhi<\/jats:italic>, while 256 (41%) and 229 (37%) were negative, respectively. There was a cross-reaction in 244 samples (39%). Individuals with contact with vectors, such as ticks, showed significant exposure to fleas (p\u00a0=\u00a00.0010). The study suggests a high prevalence of rickettsiosis and recommends prospective studies to assess the disease burden and strengthen surveillance and prevention in Yucat\u00e1n, considering factors like temperature and ecological changes.<\/jats:p>","DOI":"10.1017\/s0950268824001894","type":"journal-article","created":{"date-parts":[[2025,1,7]],"date-time":"2025-01-07T21:27:43Z","timestamp":1736285263000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":3,"title":["SFG and TG seropositivity in Humans suspected of TBD in Yucatan, Mexico"],"prefix":"10.1017","volume":"153","author":[{"given":"Karla Rossanet","family":"Dzul Rosado","sequence":"first","affiliation":[{"name":"Universidad Aut\u00f3noma de Yucatan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos Aaron","family":"Pe\u00f1a Bates","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Enfermedades Respiratorias Ismael Cos\u00edo Villegas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin Ra\u00fal","family":"Tello","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Yucatan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henry R.","family":"Noh-Pech","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Yucatan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando I.","family":"Puerto","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Yucatan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6918-1917","authenticated-orcid":false,"given":"Oghenekaro","family":"Omodior","sequence":"additional","affiliation":[{"name":"West Virginia University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,1,8]]},"reference":[{"key":"S0950268824001894_r12","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268819001390"},{"key":"S0950268824001894_r8","article-title":"Suspected and confirmed vector-borne Rickettsioses of North America associated with human diseases","volume":"3","author":"Yoshimizu","year":"2018","journal-title":"Tropical Medicine and Infectious Disease"},{"key":"S0950268824001894_r6","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0010354"},{"key":"S0950268824001894_r25","doi-asserted-by":"publisher","DOI":"10.1111\/zph.12714"},{"key":"S0950268824001894_r24","doi-asserted-by":"publisher","DOI":"10.3390\/pathogens11111351"},{"key":"S0950268824001894_r27","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0005892"},{"key":"S0950268824001894_r31","doi-asserted-by":"publisher","DOI":"10.3390\/tropicalmed5020064"},{"key":"S0950268824001894_r13","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.32.4.949-954.1994"},{"key":"S0950268824001894_r28","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.18-0029"},{"key":"S0950268824001894_r32","unstructured":"32.
