New CDC Report: Drug-resistant TB will rise if we don’t stop spreadA new CDC study provides compelling evidence that drug-resistant tuberculosis (TB) is set to rise over the next two decades in countries with some of the world's highest TB burdens. The study also suggests that person-to-person transmission, rather than inadequate treatment, will likely play an increasingly larger role in the spread of the disease in the future.
Drug-resistant TB is a major problem worldwide—and on track to get even worse.
In addition to infecting two billion people worldwide, TB can also become drug-resistant, which means the drugs we rely on to treat the disease are no longer effective. Drug-resistant TB is found in every country in the world and can kill millions if left unchecked or undiagnosed.
Using a complex mathematical model that brings together the best available data from multiple sources, the new CDC study, published in The Lancet Infectious Diseases, reports:
- The proportion of new drug-resistant TB cases in four key high-burden countries will increase substantially by 2040, unless there are major changes in the global response.
- Acquired drug resistance, or resistance due to inadequate TB treatment, will cause fewer cases over time.
- Person-to-person transmission, rather than inadequate or ineffective treatment, is likely to play an increasingly larger role in the transmission of drug-resistant TB over time.
The paper underlines the importance of working together to:
- Strengthen infection control measures and intensify contact tracing to stop transmission from person to person.
- Focus on stopping spread of TB in households, health centers, and communities.
- Develop more effective diagnostic tests to rapidly and accurately detect drug-resistant TB.
CDC is on the frontlines to combat resistant TB at home and abroad.
