The reports from covid-19 patients are disconcerting. Only a few hours before, they were enjoying a cup of pungent coffee or the fragrance of flowers in a garden. Then, as if a switch had been flipped, those smells disappeared.
Young and old alike are affected — more than 80% to 90% of those diagnosed with the virus, according to some estimates. While most people recover in a few months, 16% take half a year or longer to do so, research has found. According to new estimates, up to 1.6 million Americans have chronic smell problems due to covid.
Seniors are especially vulnerable, experts suggest. “We know that many older adults have a compromised sense of smell to begin with. Add to that the insult of covid, and it made these problems worse,” said Dr. Jayant Pinto, a professor of surgery and specialist in sinus and nasal diseases at the University of Chicago Medical Center.Recent data highlights the interaction between covid, advanced age and loss of smell. When Italian researchers evaluated 101 patients who’d been hospitalized for mild to moderate covid, 50 showed objective signs of smell impairment six months later. Those 65 or older were nearly twice as likely to be impaired; those 75 or older were more than 2½ times as likely.
