WEDNESDAY, June 7, 2023 (HealthDay Information) — One of many signature signs of COVID-19 an infection within the early months of the pandemic was a lack of the sense of odor.

Now, new analysis finds that’s now not the case, due to the brand new variants which were circulating extra not too long ago.

The danger of dropping sense of style or odor is now solely about 6% to 7% of what it was in the course of the pandemic’s early levels, based on researchers at Virginia Commonwealth College (VCU) College of Drugs in Richmond, Va.

“At the start of the pandemic, odor and style loss have been thought of widespread signs of COVID-19. Earlier than viral exams have been readily accessible, we relied much more on such signs to diagnose these contaminated. Nonetheless, as totally different variants of the COVID-19 virus have emerged, the sorts of signs mostly skilled modified as effectively,” stated examine creator Dr. Evan Reiter, who’s the medical director of VCU Well being’s Odor and Style Problems Middle.

For the examine, the researchers used a nationwide database of greater than 7 million sufferers who examined constructive for COVID-19, calculating the prevalence of odor and style loss as a symptom of the virus throughout peak durations of an infection for every variant wave.

The group discovered that the dangers of odor loss from a COVID-19 an infection for Alpha and Delta, each pervasive variants in 2021, have been solely 74% and 64% of what was noticed within the early levels of the pandemic.

They noticed even steeper declines in lack of odor in 2022 and early 2023, as Omicron variants dominated. The danger of odor loss from an infection was as little as 6% in contrast with 2020 charges.

“This information exhibits that odor and style loss is now not a dependable indicator of COVID‐19 an infection,” Reiter stated. “This implies that you would be able to’t rule out COVID-19 in case you are feeling sick however haven’t misplaced your sense of odor. This additionally signifies that in case you have misplaced your sense of odor, it’s not a assure that it’s from a COVID-19 an infection.”

The findings have been printed not too long ago within the journal Otolaryngology — Head and Neck Surgical procedure.

Researchers don’t know why fewer folks are actually dropping their sense of odor with an infection, however greater immunity to the virus may very well be an element.

“We don’t have the info on what’s inflicting this decline in odor loss as a symptom of COVID-19, however I might speculate that this is perhaps associated to our elevated immunity to the virus, both via vaccines or having an earlier an infection, as this usually helps scale back the severity of future infections,” Reiter stated in a college information launch.

“Whereas the danger of odor loss is way much less prevalent than the preliminary waves of COVID-19, we’re nonetheless seeing sufferers who’ve both utterly misplaced or have a distorted sense of odor, which might take a big toll on their high quality of life. There are a good variety of sufferers who’ve bother sustaining a nutritious diet as a result of there are such a lot of meals which are displeasing to them,” Reiter defined. “Fortunately, there’s numerous work being executed in hopes of discovering an efficient remedy for these affected by this situation.”

Funding for the examine was supplied by the MEDARVA Basis. A group that supplied information for the examine was partially funded by the U.S. Nationwide Institutes of Well being’s Scientific and Translational Science Award.
