THURSDAY, JUNE 24, 2021 (HealthDay News) – After almost a year, almost all patients in a French study were lost smell After regaining that ability after an attack by COVID-19, investigators reported.

“COVID-19 related permanent anosmia [loss of smell] he has an excellent prognosis, with almost complete recovery in a year, ”according to a team led by Dr. Marion Renaud, an otolaryngologist at the University Hospital of Strasbourg.

In the beginning pandemic, doctors who treat infected people SARS-CoV-2 began to realize that sudden loss of odor was a hallmark of the disease. It is believed to be a “peripheral” associated with COVID inflammation“is to blame for the essential nerves for olfactory function in these cases.

But as the months passed, and many patients did not regain their sense of smell, some began to worry that the damage might be permanent.

New research should alleviate these fears.

In the study, the French group followed the sense of smell of 97 patients (67 women, 30 men), with an average age of about 39 years. They all lost their sense of smell after hiring COVID-19.

Patients were asked to make any improvement in odor capacity four months, eight months after one year of odor loss. Approximately half of them underwent specialized tests to measure their ability to smell.

According to the four-month mark, objective studies of 51 patients showed that about 84% (43) had regained their sense of smell, and six of the remaining eight patients had achieved an eight-month mark. Only two of the 51 patients examined through specialized studies showed an initial diagnosis of impaired sense of smell, and a year later, the findings showed.

Overall, 96% of patients were objectively cured within 12 months, Renaud’s team reported. The research was published online on June 24th JAMA open network.

Dr. Theodore Strange is the interim president of medicine at Staten Island University Hospital in New York City. He was not involved in the new investigation, but said the findings were “very encouraging.”


“The good news is that odor loss is not a persistent sequence of COVID disease,” Strange said.

Reporting this sentiment, Dr. Eric Cioe-Peña, Director of Global Health at Northwell Health in New Hyde Park, NY, said the findings, while very welcome, should remind everyone (especially young people) of SARS-CoV- 2 infection can cause significant long-term damage.

“It’s important that while people are looking at the vaccine, some determine whether the risk is worth the benefit, not only hospitalization and death, but also these” long-term “symptoms that can affect people for months and years after recovering from the virus.” stated Cioe-Peña.

“The most important thing to get rid of this research,” he said, “is to get vaccinated and to avoid exposure to long-term symptoms first.”
