During the COVID-19 pandemic, many patients experienced a loss of taste and smell during and after being infected with SARS-CoV-2. A retrospective study by researchers at Massachusetts Eye and Ear, a member of the Mass General Brigham healthcare system, investigated the loss of olfactory and gustatory senses and estimated that about a quarter of Americans who had COVID-19 reported only partial or no recovery of taste or smell. The results are published in The Laryngoscope.

"We wanted to quantify the national impact of smell disorders resulting from COVID," said Neil Bhattacharyya, MD, FACS, Professor of Otolaryngology at Mass Eye and Ear. "With this data we can understand, in big numbers, how many people lost their sense of smell or taste due to COVID infection and how many people never fully recovered those senses."
