What the future holds for the global fight against tuberculosis
Accelerating diagnosis through digital and point‑of‑care technologies
Next‑generation rapid tests are moving from the lab to the clinic floor. Mobile‑ready molecular platforms can now deliver results in under an hour, cutting the diagnostic gap that still leaves millions untreated. Countries that have piloted handheld GeneXpert devices report a 30% increase in confirmed cases within the first six months.
New drug regimens promise shorter, safer treatment for drug‑resistant TB
Emerging all‑oral regimens are trimming treatment length from 18‑24 months to as few as six months, while maintaining high cure rates. Clinical trials of novel diarylquinolines show success rates above 80% even for extensively drug‑resistant TB (XDR‑TB).
Vaccine breakthroughs could rewrite the TB narrative
With 18 candidates in clinical evaluation, the pipeline is at its most robust in two decades. The latest Phase 3 trials of a recombinant protein vaccine have demonstrated a 50% reduction in infection among adolescents, a milestone that could shift TB from a chronic threat to a preventable disease.

Social protection: the missing link to sustainable impact
Evidence shows that linking TB care with cash transfers, nutrition support, and housing assistance cuts default rates by up to 40%. Nations such as Mongolia have reached 94% coverage of social protection for TB patients, illustrating the power of multisectoral collaboration.

Financing the future: closing the funding gap
Global financing must climb from the current quarter‑of‑target level to meet the US$22 billion annual goal by 2027. Innovative financing mechanisms—such as blended finance, health bonds, and results‑based aid—are already being tested in high‑burden countries.
Policymakers are urged to adopt domestic resource mobilisation strategies that align TB funding with broader health‑security budgets, ensuring resilience against future donor fluctuations.
Key trends to watch in the next decade
- Widespread use of AI‑driven diagnostics in primary care.
- Standardisation of ultra‑short drug regimens for MDR‑TB.
- Regulatory approval of at least one highly effective TB vaccine.
- Scale‑up of cash‑plus‑care models that integrate health and social services.
- Growth of public‑private partnerships that unlock new financing streams.
Frequently Asked Questions
- How soon could a new TB vaccine be available?
- Phase 3 trials are already showing efficacy; widespread rollout could begin within the next 5‑7 years pending regulatory approval.
- What is the most effective way to reduce drug‑resistant TB?
- Rapid molecular testing combined with short, all‑oral treatment regimens dramatically cuts transmission and improves cure rates.
- Why is social protection crucial for TB control?
- Financial and nutritional support address the underlying determinants of disease, keeping patients in care and preventing relapse.
- Can private sector investment replace declining donor funding?
- Private capital can complement public resources, especially through innovative financing models, but sustained political commitment remains essential.
- What role does digital health play in TB elimination?
- Digital tools streamline case notification, treatment monitoring, and patient engagement, leading to higher success rates.
