Just offering this up for those who are interested in the testing aspect. I'm not going to post it in the links section, here are the key points which struck me.
Loss of smell, or anosmia, and of taste (or dysguesia) were early findings of studies and anecdotal reports from China when COVID-19 emerged there, and have been noted since in the United States, South Korea, Italy, Iran and France, among other nations.
“We now know that almost everyone who has COVID-19 has some degree of smell loss, at least early in the disease process,” Dr. Doty, said in a recent interview. “And we know that the most common cause of smell loss in the general population, aside from COVID-19, is from [other] viruses.”
Dr. Doty has been involved in a major study in Iran to measure loss of smell. Published in International Forum for Allergy and Rhinology in April, the study is a bellwether for objective studies of smell loss in COVID-19.
In this study, Dr. Doty and colleagues demonstrated that decreased smell function, though not always anosmia, is a major marker for SARS-CoV-2 infection. Notably, 98% of patients demonstrated some smell dysfunction. Fortunately, most individuals who lose their sense of smell to COVID-19 get it back within three to four weeks, a finding reinforced by studies initiated at the Perelman School of Medicine and elsewhere.
