[The global importance of tuberculosis].

Area of Science:

• Public Health
• Infectious Diseases
• Epidemiology

Context:

• Tuberculosis (TB) prevalence has significantly decreased in industrialized nations due to chemotherapy advancements.
• However, TB remains a critical public health issue in resource-limited countries, exacerbated by HIV co-infection in sub-Saharan Africa.
• Global estimates indicate over 9 million new TB cases annually, with significant challenges in drug access.

Purpose:

• To highlight the contrasting global burden of tuberculosis.
• To underscore the challenges posed by drug-resistant TB strains in low-income settings.
• To emphasize the need for international support in healthcare infrastructure and medication access.

Summary:

• Tuberculosis mortality has dramatically reduced in industrialized countries since the 1950s chemotherapy introduction.
• Indigenous elderly populations and immigrants from high-prevalence regions now represent the majority of TB cases in developed nations.
• Resource-constrained countries face ongoing TB challenges, with sub-Saharan Africa experiencing increased incidence due to HIV, and drug shortages fostering resistance.

Impact:

• The findings underscore the persistent global health threat of tuberculosis, particularly in vulnerable populations and low-resource settings.
• Addressing TB requires international collaboration to bolster healthcare systems and guarantee uninterrupted access to essential antituberculosis and antiretroviral drugs.
• Combating drug-resistant tuberculosis strains necessitates improved drug supply chains and treatment accessibility worldwide.
