Tuberculosis: An Ongoing Global Threat.

Tuberculosis (TB) remains one of the world's most urgent public health challenges, with a substantial global burden that continues to affect millions annually. According to the World Health Organization (WHO) Global Tuberculosis Report 2024, approximately 10.6 million people developed TB in 2023, resulting in 1.6 million deaths. The highest incidence rates persist in low- and middle-income countries, where socioeconomic determinants such as poverty, malnutrition, overcrowded living conditions, and limited access to quality healthcare exacerbate disease transmission and worsen outcomes. The emergence and spread of drug-resistant TB, including multidrug-resistant (MDR-TB), extensively drug-resistant (XDR-TB), and totally drug-resistant (TDR-TB) strains, pose significant challenges to effective treatment and control, contributing to increased mortality and healthcare costs. The coronavirus disease-2019 (COVID-19) pandemic has further disrupted TB services worldwide, causing declines in case detection, delayed diagnoses, and interruptions in treatment, thereby reversing years of progress. Despite the availability of effective vaccines and treatment regimens, gaps in awareness, funding, healthcare infrastructure, and social determinants of health hinder global elimination efforts. Coordinated, multisectoral strategies are essential to address this complex epidemic, improving diagnostic capacity, expanding access to comprehensive treatment, combating stigma, addressing socioeconomic barriers, and investing in research for novel prevention and therapeutic tools. These efforts are critical to achieving the WHO's End TB Strategy targets and ultimately eliminating TB as a public health threat.
