In July 2023, while walking in a wooded area near Caraguatatuba on the northern coast of S\u00e3o Paulo, a 37-year-old man and his dog were bitten by bont ticks of the species Amblyomma ovale<\/em>, which carried the bacterium Rickettsia parkeri<\/em>. Six days later, the man developed flu-like symptoms and a red lesion on his ankle where he had been bitten. Over the following days, the lesion worsened. When he first visited a healthcare center, he was advised only to take an anti-inflammatory drug. Nearly a month later, having seen no improvement, he returned and was prescribed another medication, which again had no effect. Only on the third visit did laboratory tests reveal abnormalities consistent with Rickettsia<\/em> infection, but he still did not receive a definitive diagnosis. Antibiotic treatment then resolved the symptoms. The case, confirmed through molecular analysis by researchers from the University of S\u00e3o Paulo (USP) and the S\u00e3o Paulo State Health Department (SES-SP), was recorded as the first recorded instance of spotted fever caused by R. parkeri<\/em> on the coast of S\u00e3o Paulo. It was the sixth recorded case of the disease in Brazil. The dog exposed to the same ticks remained asymptomatic and did not require treatment (Zoonotic Diseases<\/em><\/a>, September 15).<\/p>\n","protected":false},"excerpt":{"rendered":"First case of spotted fever confirmed on the coast of S\u00e3o Paulo","protected":false},"author":475,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[229,260],"coauthors":[785],"class_list":["post-576791","post","type-post","status-publish","format-standard","hentry","category-notes","tag-epidemiology","tag-public-health"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/576791","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=576791"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/576791\/revisions"}],"predecessor-version":[{"id":576801,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/576791\/revisions\/576801"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=576791"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=576791"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=576791"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=576791"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
