Q and A


Are taste and smell changes common with COVID-19?


The most common symptoms of COVID-19 include fever and a dry persistent cough .

Early anecdotal reports in the US also included taste and smell changes and last week a study was published that confirm these as symptoms too. [1]

The US study reported that smell and taste loss were reported in 68% (40/59) and 71% (42/59) of people who had COVID-19, respectively. This compared to only 16% (33/203) and 17% (35/203) of people that did not have COVID-19. People reporting smell and taste changes were about ten times more likely to have COVID-19.

Two other studies have reported more details. [2, 3]

The letter in JAMA reported that taste and smell changes occurred in about 1 in 3 people with coronavirus. Also, that this could occur at any time – ie before or after other symptoms. In a few people (about 3%) this was the only symptom of coronavirus.
