An investigation published in the journal Jama Otolaryngology-Head & Neck Surgery revealed that between 700,000 and 1.6 million people in the United States who had Covid-19 lost or suffered a change in smell that has lasted more than six months. For researchers at the Washington University School of Medicine in St. Louis, they believe it is likely that this statistic is not being given the necessary attention.
Since the coronavirus pandemic it’s known that one of the possible conditions of contracting the disease is the loss of smell, something that became a “emerging public health concern“, according to the publication.
Advancing scientific research closely follows the frequency with which smell disorders occur due to the fact that many patients suffer from it even after the acute stage of the disease. Something that It is intended to remain on alert also for when the pandemic ends.
Prior to the onset of the coronavirus, 13.3 million 40-year-old adults suffered from what is scientifically called Olfactory dysfunction (OD) or chronic olfactory dysfunction (COD).
With the onset of the pandemic, while the new study revealed that most people regain their sense of smell over time, on the other hand it suggested that some patients may never get it back, which would be a concern for scientists since the figures would be very high in relation to the previous statistical cases of the Sars Cov- 2.
“These data suggest an emerging public health concern from OD and the urgent need for research that focuses on treating olfactory dysfunction caused by Covid-1.9 ″, they warned Amish Khan, Dorina Kallogjeri and Jay Piccirillo, authors of the publication.
Previous studies had determined that 72% of people with coronavirus recovered their sense of smell after a month, although for some cases the recovery process is even much slower.
What are the risks of not having a sense of smell?
Losing your sense of smell can be a health risk. It is estimated that people who lack this sense have more than twice as likely to experience dangers from eating spoiled food.
Loss of smell affects quality of life and deteriorates health since It could lead to anxiety or depression as well as eating and weight problems. according to previous studies.
With the emergence of the coronavirus, studies were carried out on thousands of people around the world. The data provided by the investigations have revealed that olfactory neurons are targets for Covid-19 regardless of variant.
