Research found that Kovid-19’s odor loss may be a ‘highly reliable indicator’



Researchers based in the United Kingdom have written in their study that people who lose either smell or taste should consider self-isolation, even if they have no other symptoms.

“Our findings suggest that loss of smell and taste is a highly reliable indicator that someone is likely to be a Kovid-19 and if we are to reduce the spread of this pandemic, it is now being used globally by governments themselves To be considered as a criterion. ” Isolation, testing and contact tracing, ”University College London and University College London Hospitals Rachel Raetham, who helped lead the study team, said in a news release on Thursday.

The team studied 590 volunteers who experienced a new loss of smell or taste, and they tested 567 of them for the Kovid-19.

Of the 567 people tested, 77.6% tested positive for the Kovid-19 antibody. Overall, 80.4% of the participants reported loss of smell and 77.8% of people tested positive to taste loss, the researchers reported in the PLOS Medicine Journal.

Of those who tested positive for antibodies, about 40% had neither fever nor cough.

Batterham and his colleagues also found that participants with odor loss alone were nearly three times more likely than patients with taste loss of the Kovid-19 antibody, and four times more likely than participants with combined loss of odor and taste Was likely to happen. Are antibodies.

“These findings suggest that a loss of smell is a highly characteristic symptom of Kovid-19 as opposed to a loss of taste,” the researchers wrote in the study.

The study recruited its volunteers from 23 April to 14 May during the Kovid-19 outbreak in London. The findings come with some limitations, including that the study does not include a comparative group of people who do not lose their sense of smell and / or taste.

Overall, loss of smell – anosmia – emerged early in the epidemic as a potential Kovid-19 symptom. In May, it was added to the official list of coronovirus symptoms in the United Kingdom, the Department of Health and Social Care announced.

At the time, a government statement said that “all individuals should self-isolate if they develop a new persistent cough or fever or anosia.”
