U.S. researchers are training dogs to seek out people with COVID-19 who are asymptomatic by teaching them to smell the odor of an infected person. They hope to eventually dispatch specially trained K-9s to screening checkpoints at public places, like airports and schools, to help identify undiagnosed COVID-19 cases.
