A new study may shed some light on why certain COVID-19 patients lose their sense of smell and taste. Researchers from Johns Hopkins University say the coronavirus binds with a cell receptor called ACE2. Turns out that cells in the nose contain some of the highest concentrations of ACE2 - making them a prime target for infection. While more research is needed, this could explain why some COVID patients lose their sense of smell and possibly help us understand how the viral infection spreads in the body. [NBC]
