Coronaviruses are a large family of viruses that can cause illness in people and animals.

Human coronaviruses are common throughout the world. Some human coronaviruses were identified many years ago and some have been identified recently. Human coronaviruses commonly cause mild to moderate illness in people worldwide. Several human coronaviruses, MERS-CoV and SARS-CoV, have been known to frequently cause severe illness.

For more information on seasonal coronaviruses, see the CDC's webpage on Common Human Coronaviruses.

What are the symptoms?

Common human coronaviruses usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. Most people get infected with these viruses at some point in their lives. These illnesses usually only last for a short amount of time. Symptoms may include:

  • Runny nose
  • Headache
  • Cough
  • Sore throat
  • Fever
  • A general feeling of being unwell

What you can do

To avoid getting sick and spreading this or any other respiratory diseases, wash your hands with soap and water, cover your cough, and stay home if you are sick. Also be sure to get a flu shot. The flu, another type of respiratory virus, can be very dangerous to children, older adults, and those with compromised immune systems.
