COVID-19 breath tests could be the future of living with the virus, but this pandemic solution has a catch

Whether it is a PCR test or the at-home variety, sending a swab up the nose to swirl around and test for COVID-19 has become a familiar but uncomfortable part of living through the pandemic. However, what if there was an alternative? For the first time, health authorities in the United States have given the green light to a COVID-19 breathalyser, a device promised to deliver results in less than three minutes. As new sub-variants once again push up case numbers, some experts hope it will be the first of many new tools to diagnose and, therefore, improve the way we live with the virus. There is even hope breath testing could eventually be used to detect and monitor other conditions, such as cancer.
