Why do people with COVID-19 lose their sense of smell? Johns Hopkins Medicine researchers believe it could be because the virus first enters through the cells in our noses. The researchers found that the cells that allow our sense of smell to function carry up to 700 times more of the surface marker that SARS-CoV-2 latches on to.

With this info, the researchers are looking at ways to cut COVID-19 off at the pass by targeting those particular cells with topical anti-viral drugs or other therapies.
