Abstract:
Tuberculosis (TB) remains a significant global health concern, causing 1.5 million deaths annually. We conducted an ecological analysis to examine TB prevalence in Brazil from 2018 to 2022, focusing on its relationship with the Human Development Index (HDI) and its inequality-adjusted version HDI (IHDI). We determined significant correlation between HDI and TB prevalence for the period of 2018-2021 (P = 0.044 in 2018, P = 0.041 in 2019, P = 0.044 in 2020, and P = 0.043 in 2021). However, an unexpected rise in TB cases in 2022, despite an increase in HDI, disrupted this trend (P = 0.12), indicating additional influencing factors. The IHDI showed correlation with TB prevalence, underscoring the importance of addressing socio-economic inequalities. These findings suggest the need for targeted interventions, particularly for vulnerable populations.

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...
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.
