78% of People With Loss of Smell or Taste Had COVID-19 Antibodies

  • Study Finds Nearly 78% of People With Loss of Smell or Taste Had COVID-19 Antibodies
  • And of the people positive for antibodies, about 40% didn’t have a cough or fever.
  • Losing these senses is now a “good indicator of COVID-19,” doctors say.

lost sense of smell or taste could be a hallmark sign of COVID-19, possibly even without the presence of other common symptoms, like a cough or fever.

In a new study published in the journal PLOS Medicine, researchers surveyed 590 people who had experienced a loss of taste or smell in the previous month.

Of that group, 567 were given COVID-19 tests and nearly 78% tested positive for antibodies to SARS-CoV-2, the novel coronavirus that causes COVID-19.

Of the people who tested positive for antibodies, nearly 40% didn’t have a cough or fever during their illness.

However, the researchers did find that people who experienced just a loss of smell were nearly three times more likely to have SARS-CoV-2 antibodies than those who had just a loss of taste.

Those who had a loss of smell and taste were four times more likely to have the antibodies.
