After Hopes of Eradication, the World’s Deadliest Infection is Creeping Back in the US With a Vengeance

After decades of progress that led many to believe tuberculosis (TB) could be eliminated, the world’s deadliest infectious disease is making a troubling comeback. Caused by the bacterium Mycobacterium tuberculosis, TB primarily affects the lungs and spreads through airborne droplets, sometimes remaining dormant in individuals before becoming active and life-threatening. While antibiotics introduced in the 1950s dramatically reduced deaths, early success led to complacency, including reduced public health funding, which may now be contributing to the disease’s resurgence.

Since 2021, TB cases have been rising steadily in the United States, the United Kingdom, and globally. The US has recorded consecutive annual increases over the past few years, including a notable outbreak in Kansas, while the UK has experienced its sharpest rise since surveillance began. Globally, the World Health Organization (WHO) reported that TB cases reached their highest recorded levels in 2024. Experts attribute part of this rebound to disruptions caused by the COVID-19 pandemic, which diverted healthcare resources and allowed other infectious diseases to regain ground.

Beyond pandemic effects, the resurgence is increasingly seen as a symptom of deeper systemic problems. TB is strongly linked to poverty, overcrowding, poor nutrition, and underfunded health systems – conditions that are worsening in many regions. Public health experts say that TB’s return is a warning sign of broader failures in disease prevention and global cooperation, emphasizing that in an interconnected world, neglecting infectious diseases anywhere poses risks everywhere.
