With stories spreading about COVID-19 patients losing the ability to smell and taste, we asked expert @stevenmunger what science can actually tell us about the potential link — and what to do if it happens to you. 
2) If you suddenly feel like you can’t smell or taste, self-isolate and immediately call your physician, or one of the hotlines set up for reporting #COVID2019. “Act like you’re infected until directed otherwise by your physician,” @stevenmunger says.
3) In the past few days, scientists around the world who study smell and taste have banded together in the group @GCChemosensoryR to fast-track gathering data on the phenomenon and to develop tests patients can do at home.
4) Once we know more, smell could be a useful indicator.
“It could be as simple as scratch-and-sniff tests sent to homes that people take themselves and report to their physician,” @stevenmunger says.
