Rickettsial and leptospiral infections have been continuously increasing throughout the past decade in Yucatan, Mexico. Leptospirosis is a zoonotic disease caused by aerobic spirochetes, while rickettsiosis is an arthropod-borne disease. In 2020, 16% of all rickettsiosis cases and 10% of leptospirosis in the country originated in Yucatan. The objective of the present case report was to document an unusual case of probable coinfection with Rickettsia and Leptospira with emphasis on clinical manifestations and the epidemiological context that may orient future multidisciplinary measures. Here, we presented the case of a 12-year-old female whose mother had recently recovered from a rickettsial infection. The patient presented with fever and developed unspecific signs and symptoms of infection; however, her condition quickly deteriorated with gastrointestinal, hepatic, renal, and neurological dysfunction. After discounting rabies and identifying infection with Rickettsia and Leptospira, antibiotic treatment was indicated, but it was too late to prevent death. Simultaneous infections of Rickettsia and Leptospira may be considered in endemic regions when environmental, epidemiological, and clinical conditions converge.<\/jats:p>","DOI":"10.3390\/pathogens10080914","type":"journal-article","created":{"date-parts":[[2021,7,20]],"date-time":"2021-07-20T23:19:51Z","timestamp":1626823191000},"page":"914","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Clinical Manifestations in a Fatal Case of Probable Rickettsia and Leptospira Coinfection in Yucatan, Mexico"],"prefix":"10.3390","volume":"10","author":[{"given":"Karla R.","family":"Dzul-Rosado","sequence":"first","affiliation":[{"name":"Center for Regional Research, \u201cDr. Hideyo Noguchi\u201d Biomedical Unit, M\u00e9rida 97000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Fidelia","family":"Cardenas-Marrufo","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Universidad Aut\u00f3noma de Yucat\u00e1n, M\u00e9rida 97000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2437-320X","authenticated-orcid":false,"given":"Cesar","family":"Lugo-Caballero","sequence":"additional","affiliation":[{"name":"Center for Regional Research, \u201cDr. Hideyo Noguchi\u201d Biomedical Unit, M\u00e9rida 97000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1324-9097","authenticated-orcid":false,"given":"Alberto","family":"Alvarez-Baeza","sequence":"additional","affiliation":[{"name":"School of Medicine, Universidad Marista de M\u00e9rida, M\u00e9rida 97300, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0230-0731","authenticated-orcid":false,"given":"Nina","family":"Mendez-Dominguez","sequence":"additional","affiliation":[{"name":"School of Medicine, Universidad Marista de M\u00e9rida, M\u00e9rida 97300, Mexico"},{"name":"Hospital Regional de Alta Especialidad de la Pen\u00ednsula de Yucat\u00e1n, M\u00e9rida 97133, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,21]]},"reference":[{"key":"ref_1","unstructured":"Secretar\u00eda de Salud (2021, June 27).
