October 3, 2020 /--- -- Four out of five people who test positive for COVID-19 antibodies have lost their sense of smell and/or taste, according to a new study by Professor Rachel Batterham of the University of London on PLOS Medicine.
COVID-19 may cause loss of taste and smell, but its prevalence is unclear, and the importance of olfactory and/or taste loss as a predictor of COVID-19 is unclear.
to assess sero-positive rates of SARS-CoV-2 antibodies in people with severe loss of smell and/or taste, the researchers recruited 590 self-reported.
, 567 participants with odor and/or loss of taste were tested for SARS-CoV-2 antibodies after confirming symptoms through telemedicine counseling.
(Photo: www.pixabay.com) test results show that 78 percent of people have SARS-CoV-2 antibodies in their bodies, and people with loss of sense of smell are three times more likely to develop SARS-CoV-2 antibodies than people with loss of taste, suggesting that loss of smell is a highly specific symptom of asthma.
40 percent of the 78 percent of participants who tested positive for antibodies had neither cough nor fever.
Despite the limitations of the study, such as self-reporting taste/olfactory changes and lack of control groups, the researchers believe that evidence suggests that odor loss, such as testing, case isolation and treatment strategies, should be given more consideration in COVID-19 public health measures.
findings are also significant for policymakers around the world, as most countries do not recommend self-isolation and testing based on severe odor/taste losses.
study suggests that over-reliance on cough and fever as the main symptoms of COVID-19 may be defective.
Rachel Batterham, who is in charge of the study, said: "Early self-identification of COVID-19 symptoms and rapid self-isolation and PCR testing are essential to limiting the spread of the disease.
, most countries in the world do not use sudden olfactory abnormalities as a symptom of COVID-19.
