The impacts of tuberculosis (TB) are usually discussed in terms of public health and human suffering. Now, new research presented at the 2026 ATS International Conference shows that TB is also driving a massive global economic crisis.
Researchers found that TB wipes out an estimated 0.8 percent of the world’s total economic potential every year. This burden is not distributed equally, with losses concentrated overwhelmingly in low- and middle-income countries, especially in South Asia and sub-Saharan Africa, the study showed. The findings demonstrate that investments in public health programs to control TB don’t just save lives but also protect economic stability and productivity, said author Hardik D. Desai, MBBS, independent clinical and public health researcher at AB Plus Multispeciality Hospital in Ahmedabad, Gujarat, India.
“TB is still costing the world an enormous amount, both in human suffering and economic productivity,” he said. “Even in the modern era, it remains a disease that is silently draining national economies.”
For the study, researchers analyzed disability-adjusted life year (DALY) data for TB and national gross domestic product data (GDP) from the World Bank.
Staggering penalty
They found that, in 2023 alone, TB was associated with an estimated $1.35 trillion in lost welfare globally. Just 22 countries represented 80 percent of this total burden.
“In some countries, TB-related losses represented more than 2 percent of national GDP-equivalent welfare, which is a staggering penalty for a largely preventable and treatable disease,” Dr. Desai said.
The concentration of economic impacts suggests that targeted, strategic interventions in the most affected regions could have enormous global benefits, he said.
Economically productive years
A key finding was that TB disproportionately affects people during their most economically productive years. This traps families in poverty and it impacts workforce participation, household income, and long-term national development, he added.
The study underscores the need for countries to commit financially to initiatives like the World Health Organization’s End TB Strategy and national programs to eliminate TB, Dr. Desai said.
“These findings are important because they change how TB should be discussed at the policy level,” he said. “Too often, TB is framed only as a medical or infectious disease problem. Our results show that it is also a major economic and equity issue.”
Researchers plan to follow up with studies examining how the economic burden of TB varies across age groups, sexes, and socioeconomic settings. They also plan to follow up with forecasting models to estimate how much economic loss could be prevented by TB prevention and treatment programs. Finally, the researchers will compare the economic impacts of TB with other major diseases.
