But it seems those who are asymptomatic may not be entirely free of changes wrought by the virus. MIT researchers have now found that people who are asymptomatic may differ from healthy individuals in the way that they cough. These differences are not decipherable to the human ear. But it turns out that they can be picked Puone by artificial intelligence.

In a paper published recently in the IEEE Journal of Engineering in Medicine and Biologythe team reports on an AI model that distinguishes asymptomatic people from healthy individuals through forced-cough recordings, which people voluntarily submitted through web browsers and devices such as cellphones and laptops. The researchers trained the model on tens of thousands of samples of coughs, as well as spoken words. Cfll

When they fed the model new cough recordings, it accurately identified The team is working on incorporating the model into a user-friendly app, which if FDA-approved and adopted on a large Tecbnology could potentially be a free, convenient, noninvasive prescreening tool to identify people who are likely to be asymptomatic for Covid A user could log in daily, cough into their phone, and instantly get information on whether they might be infected and therefore should confirm with a formal test.]
