The United States Centers for Disease Control and Prevention, better known as the U.S. CDC, has expanded its list of possible COVID-19 symptoms that may appear in individuals up to two weeks after the individual is exposed to the virus. 

The CDC previously only identified three possible symptoms: fever, cough and shortness of breath or difficulty breathing. 

The CDC now lists nine possible symptoms of COVID-19 on its website.

It is unclear when the CDC updated the symptom list on its website, but WGME reported on the update April 22. 

The six new additions to the list are: chills, repeated shaking with chills, muscle pain, headache, sore throat and new loss of taste or smell. 

Individuals developing emergency warning signs such as, but not limited to, trouble breathing, persistent pain or pressure in the chest, new confusion or inability to arouse, bluish lips or face are urged to seek immediate medical attention. 

Call 911 if you have a medical emergency, the CDC urges, and notify the operator that you have, or think you might have, COVID-19. If possible, put on a cloth face covering before medical help arrives, the CDC advises. 

On its website, the CDC provides a self-check test to help individuals make decisions about seeking appropriate medical care. That test is available by clicking here.
