Abstract
Background
Tuberculosis, characterized by the World Health Organization as a global health emergency, is a disease of global impact.
Objective
To investigate a series of tuberculosis cases during 17 years in Ouro Preto, Minas Gerais, Brazil, considering the historic relationship between mining and the disease.
Method
Data was obtained through the city's system of tuberculosis notifications, plus active search through medical records, and compared to the amount of notified cases present in the System of Information of Notifications Complications. For trend analysis, polynomial regression models were used for the historic series.
Results
The average age was 40.3 ± 16.4 years old. Men showed 2.23 times more cases and chances (odds ratio) of 2.07 times higher for negative outcomes. The most observed form was lung (85%) and HIV serology was performed in only 16.3% of the logs. The main observed outcome was a cure (70%) and negative outcomes accounted for 20.2% of the logs. The average incidence rate was 29.76 and 16.23 cases/100 thousand inhabitants in the city and district zones, respectively.
Conclusion
Despite the historical relationship between mining and tuberculosis in the municipality, it is observed that the same still presents worrying vulnerabilities about disease surveillance, temporal series analysis suggested a decline in the proportion of cases cured between 2009 and 2015.
