Opinion | A breath of hope

As we reflected on World TB Day 2026 last week, the air we share in South Africa remains heavy with a centuries-old, unforgiving pathogen. Tuberculosis (TB) is not just a leading cause of death in our country, it is a pervasive predator that continues to stalk our most vulnerable with devastating precision. Despite our collective exhaustion with epidemics and pandemics over the past few years, we cannot look away from this enduring crisis.

TB empties chairs at family dinner tables, it orphans vulnerable children and drains the vitality of our workforce, placing a massive, unyielding brake on our national prosperity. The economic shockwave of a TB diagnosis is profound. When a breadwinner falls ill, the physical decline is followed rapidly by a financial free fall.

The loss of income, compounded by the costs of endless clinic visits and the need for bolstered nutrition, often pulls entire households below the poverty line. Families are forced to sell off meagre assets or pull children out of school, perpetuating a generational cycle of debt and desperation. TB does not just infect lungs; it paralyses livelihoods.

Yet, as clinician scientists and infectious disease epidemiologists, we must emphasise that our story is not merely one of suffering. SA has long been a global pioneer in TB science and policy. We have consistently been among the first nations to adopt and fund evidence-based diagnostics, scaling up rapid molecular testing to detect drug resistance within hours, rather than the weeks or months it took a decade ago.

We have championed ground-breaking therapeutic regimens, bravely transitioning to all-oral, shorter courses for drug-resistant TB, removing the agony of months of daily injections. We have also rapidly expanded preventative therapies to protect those most at risk. On paper, our programmatic arsenal is the envy of the developing world, backed by some of the leading researchers in the world and by a strong researcher-policy interface.

Why, then, do so many people still succumb to a disease that has been curable for decades? The truth is that we suffer from a profound and deadly implementation failure. We possess world-class tools, but they fail to benefit those who need them most due to fractured health systems, clinic bottlenecks and a leaky care cascade.

We lose people at every step, from the community to the clinic, from diagnosis to treatment initiation, and from the first pill to the last. More fundamentally, we have failed to reflect adequately on what the persistence of TB truly represents: It is a symptom of a failing society.
