Tuberculosis Costs the World $1.35 Trillion Annually
New research indicates tuberculosis drains 0.8% of the world’s economic potential annually, disproportionately affecting low- and middle-income countries.Tuberculosis (TB) is associated with an estimated $1.35 trillion in lost welfare globally, according to research presented at ATS 2026.The study found that TB eliminates approximately 0.8% of the world’s total economic potential annually, with losses concentrated in low- and middle-income countries.
RT’s Three Key Takeaways:
- Trillion-Dollar Impact: Tuberculosis resulted in an estimated $1.35 trillion in lost welfare globally in 2023, which accounts for 0.8% of the world’s total economic potential.
- Geographic Concentration: Economic losses are heavily concentrated in 22 countries, primarily within South Asia and sub-Saharan Africa, where the burden can exceed 2% of national welfare.
- Workforce Disruption: The disease primarily affects individuals during their most economically productive years, trapping families in poverty and hindering long-term national development.
Economic Burden and Human Suffering
The findings demonstrate that investments in public healthcare programs to control TB protect both lives and economic stability, said Hardik D Desai, MBBS, independent clinical and public health researcher at AB Plus Multispeciality Hospital.
“TB is still costing the world an enormous amount, both in human suffering and economic productivity,” said Desai in a news release.“Even in the modern era, it remains a disease that is silently draining national economies.”
To quantify the impact, researchers analyzed disability-adjusted life year (DALY) data and national gross domestic product (GDP) data from the World Bank.The analysis showed that just 22 countries represented 80% of the total global economic burden.“In some countries, TB-related losses represented more than 2% of national GDP-equivalent welfare, which is a staggering penalty for a largely preventable and treatable disease,” said Desai.
The study found that TB disproportionately affects people during their most economically productive years.This trend impacts workforce participation and national development while trapping families in poverty, said Desai in a news release.The results underscore the necessity for countries to fund initiatives like the World Health Organization (WHO) End TB Strategy and national programs to eliminate the disease.
“Too often, TB is framed only as a medical or infectious disease problem,” said Desai.“Our results show that it is also a major economic and equity issue.”
Researchers intend to conduct follow-up studies to examine how the economic burden varies across age groups, sexes, and socioeconomic settings.They also plan to use forecasting models to estimate how much economic loss can be prevented through TB prevention and treatment programs, and will eventually compare the impacts of TB with other major diseases.
