It might even serve as a useful screening tool, they say.
The idea of a virus infection reducing sense of smell is not new. Respiratory viral infection is a common cause of loss of smell, because inflammation can interfere with airflow and the ability to detect odors. The sense of smell usually returns when the infection resolves, but in a small percentage of cases, smell loss can persist after other symptoms disappear. In some cases, it is permanent.
Now, there’s “good evidence” from South Korea, China and Italy for loss or impairment of smell in infected people, says a joint statement from the presidents of the British Rhinological Society and of ENT UK, a British group that represents ear, nose and throat doctors. In South Korea, some 30% of people who tested positive for the virus have cited loss of smell as their major complaint in otherwise mild cases, they wrote.
