3 Deaths and 20 Cases of Spotted Fever Confirmed in Minas Gerais
The Minas Gerais State Health Secretariat (SES-MG) has confirmed three deaths and 20 cases of spotted fever in the state as of June 30, 2026. Two of the fatalities were residents of the Eastern Minas region, specifically from the cities of Córrego Novo and Mutum. Additionally, the city of Sabinópolis has one confirmed case, though no death has been reported there. Spotted fever is transmitted by the star tick (Amblyomma) and is considered one of the country's most lethal diseases. The SES-MG notes that the disease is present throughout Minas Gerais, with higher occurrences in the Central, Vale do Aço, Eastern, and Southeastern regions. The peak season for notifications typically falls between April and October, coinciding with the dry season. Prevention strategies include avoiding contact with star ticks, wearing light-colored, long clothing, using repellent, and thoroughly inspecting the body for ticks after visiting wooded or animal-populated areas. Ticks found on the skin should be promptly removed with tweezers. Historically, the disease disproportionately affects men aged 41 to 60, and the average fatality rate in Minas Gerais is approximately 30%.
This report details a public health concern regarding spotted fever in Minas Gerais, Brazil, highlighting confirmed cases and fatalities linked to tick-borne transmission. The data underscores the importance of vector control and public awareness campaigns, particularly during the dry season when tick activity is higher. The historical demographic data suggests a need for targeted prevention messaging towards middle-aged men who frequent areas where ticks are prevalent. Understanding the environmental and behavioral factors contributing to transmission is crucial for developing effective, long-term public health strategies that mitigate the disease's significant lethality rate and prevent future outbreaks.
