A group of researchers at MIT recently developed an artificial intelligence model that can detect asymptomatic COVID-19 cases by listening to subtle differences in coughs between healthy people and infected people. … The AI model correctly identified 98.5% of people with COVID-19, and correctly ruled out COVID-19 in 94.2% of people without the disease. For asymptomatic people, the model correctly identifed 100% of people with COVID-19, and correctly ruled out COVID-19 in 83.2% of people without the disease.
