Odor loss may be a ‘very reliable indicator’ of Covid-19, the research finds



The UK-based researchers wrote in their study that people who lose either smell or taste should consider isolating themselves even if they have no other symptoms.

“Our findings show that loss of smell and taste is a very reliable indicator that someone is likely to want Covid-19, and if we are to reduce the spread of this pandemic, it should now be considered by governments globally as a criterion for self-isolation, testing and contact tracking, ”said Rachel Batterham of University College London and University College London Hospitals, who helped lead the research team in a press release on Thursday.

The team studied 590 volunteers who experienced a new loss of odor or taste, and they tested 567 of them for Covid-1

9.

Among the 567 people tested, 77.6% tested positive for Covid-19 antibodies. In total, 80.4% of participants who reported odor loss and 77.8% of those who reported taste loss had a positive test result, the researchers reported in the journal PLOS Medicine.

Approximately 40% of those who tested positive for antibodies had neither fever nor cough.

Batterham and her colleagues also found that participants with loss of odor alone were nearly three times more likely than patients with only one taste loss to have Covid-19 antibodies, and participants with a combined loss of smell and taste were four times more likely to have antibodies.

“These findings suggest that an odor loss is a very specific symptom of Covid-19, as opposed to a loss of flavor despite their comparable frequency,” the researchers wrote in the study.

The study recruited its volunteers between April 23 and May 14 during the peak of the Covid-19 eruption in London. The results have some limitations, including that the study does not include a comparison group of people who did not lose their sense of smell and / or taste.

Overall, odor loss – called anosmia – occurred early in the pandemic as a possible Covid-19 symptom. In May, it was added to the official list of coronavirus symptoms in the UK, the Department of Health and Social Care announced.

At the time, a government statement said that “all individuals should isolate themselves if they develop a new continuous cough or fever or anosmia.”
