Tuberculosis (TB) is a communicable disease considered serious. The time difference between obtaining test results from a patient and starting treatment increases the chance of transmitting tuberculosis. The purpose of this article was to verify the number of confirmed cases of tuberculosis in Brazil between 2015 and 2019 according to the notification region, age group, form of the disease and closure situation. For this, a qualitative and quantitative research was carried out. Quantitative data were taken from the IT department of the Brazilian Unified Health System (DATASUS)[7]. Regions of the country with the highest HDI seem to deal better with the transmission, treatment and cure of tuberculosis. The economically active population, with greater exposure to other people, are the most affected group due to the type of transmission. The pulmonary type of tuberculosis affects the largest number of people due to the form of airborne transmission and also the performance of the body’s immune system, with the fight being maintained at the cavity level. The high rate of success in the treatment (cure) reflects that there is a real possibility of combating the bacillus. Unfortunately, the abandonment rate demonstrates how bad a social imbalance can do to public health.
