Smartphone app warns if you’ve been exposed to coronavirus
The smartphone in your pocket may soon let you know if you’ve been exposed to COVID-19.
As communities around the world consider the first steps toward reopening, there is fear that once people begin moving, the virus will spread. But COVID-19 presents unique challenges to stop its spread. Some who are infected never had symptoms; those who do fall ill can spread the disease for a day or two before experiencing a cough or body chills, some of the common COVID-19 symptoms.
Apple, Google and others, including MIT and Lincoln Laboratory, are working on a plan to use smartphones to inform those who have crossed paths with a COVID-19-infected person. They call it "exposure notification.” Voice of America interviews MIT Lincoln Laboratory's Marc Zissman on how such a system works.
