For most people, smell, taste and chemesthesis recover within weeks. In a study published last July, 72% of people with COVID-19 who had olfactory dysfunction reported that they recovered their sense of smell after a month, as did 84% of people with taste dysfunction. Claire Hopkins, an ear, nose and throat consultant at Guy’s and St Thomas’ Hospital in London, and her colleagues similarly observed a speedy return of the senses: they followed 202 patients for a month, and found that 49% reported complete recovery over that time, and a further 41% reported an improvement.
