Introduction:
Tuberculosis is an infectious disease of major public health concern. Although most studies focus on health care professionals, other economic sectors may also present conditions that favor transmission and illness.
Objectives:
To analyze the occurrence of work-related social security benefits granted for tuberculosis in Brazil and to review scientific evidence on economic activities and occupations associated with increased risk of infection, excluding health care professionals.
Methods:
This ecological study used publicly available data from the Brazilian National Institute of Social Security. Work-related temporary disability benefits (B91) granted from 2022 to 2024 and linked to codes A15 to A19 of the International Classification of Diseases, 10th revision, were included. Results were described according to the number of benefits and the corresponding codes of the National Classification of Economic Activities. In parallel, a narrative literature review was conducted using PubMed and SciELO databases, including primary studies in Portuguese and English involving workers from different productive sectors.
Results:
A total of 115 B91 benefits due to tuberculosis were granted in 2022, 123 in 2023, and 65 in 2024. The literature identified increased tuberculosis risk among workers in cleaning, laundry, baking, construction, waste collection, sewage, textile manufacturing, and mining, associated with factors such as inadequate ventilation, silica exposure, unsanitary conditions, and social vulnerability.
Conclusions:
Work-related tuberculosis extends beyond the health care sector, affecting multiple productive sectors. Recognizing these exposures is essential to guide surveillance, inspection, and prevention measures aimed at reducing occupational tuberculosis.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
