Non-invasive SKIN tests can detect Covid-19 with 83% accuracy

Covid-19 can be accurately detected by skin swabs rubbed on the face, neck or back, a study suggests. Currently, the only way to reliably detect Covid-19 is with highly-invasive swabs which go up the nose or to the back of the throat. But University of Surrey researchers say sebum -- a waxy substance made by glands in the skin -- is altered by the coronavirus and can therefore be used to detect signs of infection. Currently, the only way to reliably detect Covid-19 is with highly-invasive swabs which go up the nose or to the back of the throat. Sixty-seven hospitalised patients were recruited for the study between May and June 2020.
