A team of scientists, according to results published in the journal Nature Medicine, tracked people in the United States, the United Kingdom, and Sweden between March 24 and April 21, 2020. The app allowed people to record their symptoms in real-time.

Researchers were able to predict with almost 80% accuracy whether a person was likely to have COVID-19 symptoms based on their age, sex, and a combination of four symptoms:

  • Loss of taste or smell
  • Persistent cough
  • Fatigue
  • Loss of appetite

The study found that the loss of taste and smell was the number one predictor of whether a person was going to get sick with COVID-19, followed by extreme fatigue and acute muscle pain. The researchers stated that COVID-19 appears to cause problems in smell receptors not unlike other respiratory viruses.
