An app is said to detect Covid by phone
While still in the testing phase, the ResApp app was found to be able to accurately identify Covid-19, in 92% of infected people.
Professor Catherine Bennett, a member of ResApp's Covid-19 Scientific Advisory Board, said: "The sheer scale of this global pandemic and the potential evolution towards an endemic disease means that we need faster diagnostic tools.
"By rapidly diagnosing Covid-19, the ResApp test would significantly reduce the number of rapid antigen and PCR tests, while still maintaining the disease surveillance needed to manage the continued spread of Covid-19."
The application was tested on 741 patients in India and the US - including 446 with Covid-19.
Participants completed surveys on the symptoms they were experiencing and coughed over the phone.
The results showed that the app was able to accurately detect Covid in 92% of people with the virus.
The researchers further tested the app to see if it would detect Covid-18 specifically by testing it with the cough of 1,007 patients suffering from other respiratory illnesses, including asthma, pneumonia and respiratory tract infections.
These tests revealed that the application detected Covid-19 with 90% specificity.
Pfifer has offered to buy the app for almost $ 55 million to further refine it.
