In the remote regions of Yogyakarta, Java, tuberculosis (TB) is a silent killer. Healthcare is hard to come by, and often, when clinics do exist, they are unstaffed. This leads to undiagnosed patients spreading the disease, resulting in alarming rates of transmission and death.

What You Need to Know About Tuberculosis

TB, an airborne infection caused by Mycobacterium tuberculosis, can linger in the air for hours. While it primarily attacks the lungs, it can also affect vital organs like the kidneys. The World Health Organization urges proactive screening in high-risk areas, but many communities lack access to traditional diagnostic methods.

Antonia Saktiawati, a clinical scientist at Gadjah Mada University, highlights the desperation for active case finding, rather than relying on patients to seek care when it’s often too late for effective treatment.

Changing the Game: Breath Analysis for TB Detection

With an estimated one-quarter of the global population infected with TB, the need for rapid diagnosis is clearer than ever. "TB can be cured if detected quickly," says Jane Hill, a chemical and biological engineer at the University of British Columbia.

Hill leads the Human Breath Atlas, a groundbreaking initiative studying breath samples to unveil health signals. "Breathing is a direct window into our bodily processes," she explains, emphasizing how breath can reflect interactions between Mycobacteria and the immune system.

The Rise of eNose-TB: A Portable Solution

To combat the TB crisis in Yogyakarta, Saktiawati pioneered the eNose device, which detects volatile organic compounds (VOCs) from breath. About the size of a shoebox, it offers a portable, cost-effective solution for on-the-spot screening.

After initial tests with a commercial eNose yielded promising results, Saktiawati's team developed an in-house version, the eNose-TB, capable of offline sampling. This innovation proved invaluable during the COVID-19 pandemic, demonstrating its versatility by enabling rapid testing for multiple diseases.

Broader Implications: From Local to Global

Not limited to Indonesia, TB poses a serious threat globally. Michael McLoughlin of Zeteo Tech points out that outbreaks are surfacing even in developed nations, such as the recent cases in Kansas. Zeteo is developing the BreathBiomics mass spectrometer, a portable tool to detect diseases like TB efficiently.

Breath analysis not only is painless and universal but can also serve as a public health screening tool in crowded places like airports and malls.

The Future of TB Detection

As researchers like Zenobi and Chimowa explore breath analysis, the focus is clear: make diagnostics affordable, accessible, and rapid. The ultimate goal? Imagine breathing into a device and knowing your health status within seconds. This groundbreaking research may soon turn that fantasy into reality.
