Researchers at Yale University have developed a portable tracker that can detect the presence of Covid-19 in the air.

Scientists from the Yale School of Public Health (YSPH) have just unveiled an air sampler that can warn its wearer of the presence of SARS-CoV-2, the virus that causes covid-19, in closed environments. It can determine whether a person is exposed to the virus, which can be useful for people in environments at particular risk of exposure, for instance health care facilities or public places that see considerable amounts of foot traffic, such as restaurants.
