Coronavirus – All newsLoss of smell to a greater or lesser degree is a very common symptom in patients with mild Covid-19.
Olfactory dysfunction, according to patients’ own reports, occurs in 86% – nearly nine out of ten – of those with generally mild symptoms of the disease, according to a new European study.
The percentages are much lower in patients with moderate Covid-19 (only 4.5%) and in those in severe critical condition (6.9%). The researchers, led by Dr. Jerome Lessien of Paris Saclay University in Paris, who published the study in the Medical Journal of Internal Medicine, studied 2,581 patients from 18 European hospitals.
The average duration of olfactory problems reported by patients is almost 22 days, but almost one in four had not fully recovered their sense of smell after 60 days.
Compared to subjective patient reports, rates of olfactory loss are lower, but still quite high after an objective medical examination: found in 54.7% of mild Covid-19 cases and in 36.6% of cases moderate to very serious illness. After 60 days, it was medically established that 15.3% and 4.7% of these patients, respectively, had not regained their normal sense of smell.
“Olfactory dysfunction is clearly more common in mild forms of Covid-19 than in moderate or critical forms of the disease, and 95% of patients have regained their sense of smell six months after infection,” Lassien said .
