Scientists have created an algorithm that can accurately diagnose people with Covid-19 just by the sound of their cough. Their algorithm would underpin an app that could deliver a quicker, cheaper and less invasive way of preliminary testing for the virus, according to the experts. DeepCough, created by experts from the University of Essex, was built using 8,380 clinically-validated audio samples of people coughing. The samples were taken from hospitals in Spain and Mexico since April last year –2,339 who tested positive and 6,041 who tested negative for Covid-19. The researchers say the algorithm was able to detect with 98 percent accuracy whether or not the samples were from people infected. The two leading tests for detecting Covid-19 – antigen detection and PCR – involve swabs of bodily fluid, but the app could be rolled out for iOS and Android and potentially provide a way for people to self-diagnose.
