<div dir="ltr"><div>"Asymptomatic people who are infected with Covid-19 exhibit, by
definition, no discernible physical symptoms of the disease. They are
thus less likely to seek out testing for the virus, and could
unknowingly spread the infection to others.
<p>But it seems those who are asymptomatic may not be entirely free of changes wrought by the virus. <span class="gmail-glossaryLink">MIT</span>
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 up by artificial intelligence.</p>
<p>In a paper published recently in the <em>IEEE Journal of Engineering in Medicine and Biology</em>,
the 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.</p>
<p>The researchers trained the model on tens of thousands of samples of
coughs, as well as spoken words. When they fed the model new cough
recordings, it accurately identified 98.5 percent of coughs from people
who were confirmed to have Covid-19, including 100 percent of coughs
from asymptomatics — who reported they did not have symptoms but had
tested positive for the virus.</p>
<p>The team is working on incorporating the model into a user-friendly
app, which if FDA-approved and adopted on a large scale could
potentially be a free, convenient, noninvasive prescreening tool to
identify people who are likely to be asymptomatic for Covid-19. 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."</p>
