A ground-breaking app which can detect coronavirus in your voice has been developed in a major scientific breakthrough. The AI-powered technology is easier to use and more accurate than a lateral flow test, scientists say. The mobile app takes less than a minute to flag positive cases and gives an accurate result 89 per cent of the time and negative cases 83 per cent of the time. The accuracy of lateral flow tests varies widely and could miss between 20 per cent and 81 per cent of positive cases in different settings, according to Imperial College London. The new app could be used to very quickly screen people for the bug before they attend mass events such as concerts and big sports matches.
