Indian researchers said on Monday they were close to developing an "electronic nose" to sniff out tuberculosis on the breath - offering rapid diagnosis that could save hundreds of thousands of lives.
The "E-Nose" is a battery-operated, hand-held unit, similar to a police breathalyzer used to catch drunk drivers.
A patient blows into the device and sensors pick up TB biomarkers in the breath droplets, resulting in an almost instantaneous and highly accurate diagnosis.
The "E-Nose" is a collaboration between the International Center for Genetic Engineering and Biotechnology in New Delhi and Next Dimension Technologies in California.
TB kills close to 1.7 million people globally every year, and researchers estimate the "E-Nose" could save 400,000 lives a year in developing countries through early diagnosis, treatment and reduced transmission.
TB is currently detected through sputum tests that are costly and take several days.
On Monday, the project was awarded a $950,000 grant by the Bill and Melinda Gates Foundation and Grand Challenges Canada, a non-profit organization working on health issues in the developing world.
Each "E-Nose" would cost roughly $20-30 and its size and battery operation would make it accessible to rural communities in countries such as India with poor or non-existent power supplies.
According to the World Health organization (WHO), India leads the world in TB infections which kill close to 1,000 people every day.
TB is a contagious bacterial infection that spreads through the air. If left untreated, each person with active TB will on average infect between 10 and 15 people every year, according to the WHO.
Questions:
1. How many people die from TB every year?
2. How much was the grant awarded to the project?
3. How much will each “E-Nose” cost roughly?
Answers:
1. 1.7 million.
2. $950,000.
3. $20-30.
