Loss of smell could be a 'highly reliable indicator' of Covid-19, research says
I had a mild case of covid and the loss of smell and taste was unlike anything similar I've ever experienced. It's not like having a stuffed nose or just being less sensitive to smell. For me I could breathe just fine but could not smell or taste anything, literally zero. Even very strong smelling things did nothing for me, and food had zero taste. It's a very unusual experience and I think a dead giveaway that you had the virus (it appears near the end of an infection typically).
