Science Alert: Which are the Atypical COVID-19 Symptoms?

There's still a lot we don't know about the coronavirus that has caused a pandemic of a new disease called COVID-19. That includes what the symptoms are and how varied they might be.

The most common distinctive symptoms of COVID-19 are a dry cough, fever, and difficulty breathing.
