For many people infected with the Sars-CoV-2 virus, the first sign of contracting the disease is a loss of smell and taste; something we reported on last May. Studies have now shown that months later an unlucky minority will still be lacking these senses – while for others they may have returned somewhat distorted. While scientists try to fathom what exactly causes this and what treatments could help, we return to the archives to explore what it’s like to live without a sense of smell. The episode was part of a special series from the Guardian called Brain waves exploring the science and emotion of our everyday lives.
