14 de jun. de 2023 · Brazil has recorded 49 cases of Rocky Mountain spotted fever this year, as per figures from the Ministry of Health updated Tuesday (Jun. 13). Of these, six were fatal.
The main clinical signs and symptoms are fever, severe headache, rashes and myalgia. It is considered difficult to diagnose and underreported. The study aims to descriptively analyze the epidemiology of cases of Rocky Mountain spotted fever in Brazil from 2010 to 2021.
Although the number of confirmed cases of spotted fever has been declining in Brazil since 2005, the mortality rate (20% to 30%) is still high in comparison to other countries. This high mortality rate is closely related to the difficulty in making the diagnosis and starting the correct treatment.

Spotted fever (SF) is an infection caused by gram-negative, obligate intracellular bacteria of the genusRickettsia. The main agent of SF in Brazil is Rickettsia rickettsii. Nevertheless, other species of Rickettsiaassociated or not to SF clinical cases have been registered in several regions of the country [11. Spolidorio MG, Labruna MB, Mantovani ...
A descriptive epidemiological study was performed based on cases of spotted fever notified by investigation forms (IF) available in SINAN between 2007 and 2015. The database was accessed on March 14th, 2016. Duplicate or inconsistent information (out of the case definition proposed by the MH) were excluded from the analysis. Cases were considered s...
Between 2007 and 2015, 17,117 suspected cases of spotted fever were reported and 1,245 were confirmed in 12 states: São Paulo (n= 550, 44.2 %), Santa Catarina (n= 276, 22.2 %), Minas Gerais (n= 104, 8.5 %), Rio de Janeiro (n= 90, 7.2 %), Espírito Santo (n= 32, 2.5 %), Paraná (n= 25, 2.0 %), Ceará (n= 11, 0.9 %), Rio Grande do Sul (n= 9, 0.7 %), Goi...
An increase in the number of suspected cases of SF was observed between 2007 and 2015; however, the number of confirmed cases presented low variation. High case-fatality rates were registered in southeastern Brazil. South and Southeast regions had the highest incidence rates, with most cases being reported in São Paulo and Santa Catarina, a finding...
The results showed expansion of suspected cases of spotted fever and high case-fatality rates, which could be related to diagnostic difficulties and lack of prompt treatment. These factors may be limitations of the SF Epidemiological Surveillance System in Brazil, hence improvement of notification and investigation are crucial for to reduce morbidi...
