Impact of COVID-19 on Social, Economic, and Health Interventions for Tuberculosis and Leprosy

Introduction: The COVID-19 pandemic disrupted social interactions, family dynamics, and economic stability, disproportionately affecting vulnerable populations. Tuberculosis and leprosy perpetuate poverty and, once manifested, hinder socioeconomic development due to their high potential for disability. Methodology: This study analyzed the impact of the COVID-19 pandemic using DATASUS health data and assessed the influence of socioeconomic interventions (SAGICAD data) on tuberculosis and leprosy case notifications in Brazil. A correlation analysis was performed between regional diagnoses and variables such as Bolsa Família (a national social welfare program), BCG vaccination coverage, and COVID-19 immunization rates, applying Pearson’s correlation test. Results: No significant correlations were found between COVID-19 vaccination rates and tuberculosis/leprosy diagnoses. However, a strong negative correlation (<i>p</i> < 0.05) was observed between BCG (Bacillus Calmette–Guérin) vaccination coverage and leprosy incidence in the Northern region. The findings also suggest that social assistance programs such as Bolsa Família play a pivotal role in preventing infectious diseases in vulnerable areas. Conclusions: Understanding the complex interplay between socioeconomic determinants and public health outcomes is essential for guiding future research and informing health policies, including potential revisions to social programs and vaccination protocols.
