In this study we report five fatal cases of BSF in employees of an animal shelter in an urban area in the municipality of Rio de Janeiro in southeast Brazil after a natural disaster on 11 January 2011. Four of the cases occurred from 27 January to 11 April 2011, while the fifth fatal case was identified in April 2012. Three cases were confirmed by molecular analysis and two by epidemiological linkage. An investigation of BSF was performed in the animal shelter, and blood samples were collected from 115 employees and 117 randomly selected dogs. The presence of high levels (1024\u20134096) of antibodies against spotted fever group rickettsiae was found in three (2\u00b76%) employees and 114 (97\u00b75%) dogs. These findings emphasize the need to consider BSF as a possible cause of undifferentiated febrile illness, especially dengue and leptospirosis, in patients occupationally exposed to dogs heavily infested by ticks, mainly working at kennels and animal shelters that have inadequate space for the animals housed and frequently providing an environment conducive to exposure to pathogens such as<jats:italic>R. rickettsii<\/jats:italic>.<\/jats:p>","DOI":"10.1017\/s0950268814003161","type":"journal-article","created":{"date-parts":[[2014,12,8]],"date-time":"2014-12-08T07:50:04Z","timestamp":1418025004000},"page":"2446-2450","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":11,"title":["A cluster of<i>Rickettsia rickettsii<\/i>infection at an animal shelter in an urban area of Brazil"],"prefix":"10.1017","volume":"143","author":[{"given":"T.","family":"ROZENTAL","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
