graphic of symptoms of COVID-19

A wide range of symptoms of COVID-19 have been reported, ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure. Older adults and people who have severe underlying medical conditions such as heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness, but anyone can have mild to severe symptoms.

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

This list is not all inclusive. Please consult your medical provider for any other symptoms that are severe or concerning to you.

What are coronaviruses?

Coronaviruses are a large family of 50-plus distinct viruses which are found worldwide and infect both mammals and birds. Four coronaviruses have been circulating amongst humans for years and are believed to cause 20-40% of common cold infections per year. Two other coronaviruses have caused much more serious human illness since 2002: SARS-CoV and MERS-CoV.
