Researchers hope to trial low-cost face masks that can detect whether someone has infectious coronavirus before they display any symptoms. The sampling masks will be adapted using 3D printed strips and can trap exhaled microbes in a 30-minute period.
About 80,000 people so far 1. (infect) with the disease worldwide. Scientists claim the adapted masks could allow large groups to be checked at once, 2. could help curb the spread of the virus and avoid long 3. (stay) in quarantine.
Mike Barer, professor of clinical microbiology at the university, said: "This new approach is 4. (excite) because it could help us determine whether 5. person is infectious or not, even before symptoms of the virus have appeared. 6. (measure) how much of the virus is breathed out by using the mask sampling approach will allow us to compare levels of the virus exhaled by different individuals, and could help us focus control efforts 7. preventing spread."
Adapted masks have 8. (previous) been successfully used to screen patients for tuberculosis, researchers said.
Initially the sampling masks will be tested on patients with 9. respiratory infections and the results will then be compared to throat swab results. It is expected to take between two to three months 10. (reach) this stage.
