In Brazil, spotted fever and brucellosis are two zoonoses of increasing epidemiological importance and which have a significant impact on Brazilian public health. Spotted fever, if not treated properly, can have a high fatality rate and brucellosis is characterized by high incidence and low lethality. Rocky Mountain spotted fever is an acute infectious disease caused by the bacterium Rickettsia ricketssi, which is transmitted by the bite of an infected tick to humans. In the country, the main vectors are Amblyoma ticks, cajennense, aureolatum and dubitatum species. Brucellosis is an occupational disease and is on the Ministry of Health's list of work-related diseases. Caused by bacteria of the genus Brucella, it is transmitted to humans through direct or indirect contact with infected animals or consumption of contaminated animal products. Unpasteurized milk and dairy products are an important source of contamination. This study aims to analyze reported cases of spotted fever, hospitalizations and deaths due to brucellosis in Brazil from 2012 to 2022. Of the confirmed cases of spotted fever, 70.8% were male, with the most affected age group being 40 to 59 years old, followed by 20 to 29 years old. The number of hospitalizations recorded for brucellosis was 221, with the majority being male and the most affected age group being 20 to 39 years old. During the period studied, eight deaths caused by brucellosis were recorded, four of which were male and four female. The age group of 60 years or more presented 6 deaths. The data analyzed were collected from the Notifiable Diseases Information System (SINAN), Hospital Admissions System (SIH) and Mortality Information System (SIM). The results obtained contribute to demonstrating the epidemiological profile of spotted fever cases, hospitalizations and deaths caused by brucellosis in the country
