According to many public health experts, testing for COVID-19 is key to stopping the pandemic. Testing leads to quick identification, isolation and treatment of COVID-19 cases, including those who came into contact with infected people. It stops the spread of the virus.
Unfortunately, widespread testing in the U.S. has been limited by logistic and personnel problems, lab capacity, cost and the availability and reliability of the tests themselves. That’s why researchers at several universities and medical centers are exploring the use of smartphones to detect COVID-19, through users’ speech and coughs.
