Most of us have become familiar with the Centers for Disease Control and Prevention’s commonly cited list of coronavirus symptoms: fever, cough, and shortness of breath.
According to a report from late June, published in the journal PLOS One, these are still the most commonly reported symptoms. The report compiled and analyzed data from 148 COVID-19 studies and found that in laboratory-confirmed cases, persistent cough was the most common symptom reported, fever was the second, and shortness of breath was the third.
In April, according to NPR, the CDC added six new coronavirus symptoms to its official list: chills, repeated shaking with chills, muscle pain, headache, sore throat, and loss of taste or smell. More recently, according to Forbes, the CDC added three more: congestion or runny nose, nausea or vomiting, and diarrhea. Like the original symptoms, these may appear between two and 14 days after exposure to the virus.
These new symptoms aren’t surprising. In late March, British physicians released data warning that loss of smell, also known as anosmia, and consequent loss of taste, could be an indication of coronavirus infection.
And then there’s still the possibility that you may be infected with the coronavirus and never show symptoms at all. Though we don’t know the exact percentage of how many people with the coronavirus are asymptomatic, studies show that the number isn’t insignificant: National Institute of Allergy and Infectious Diseases director Dr. Anthony Fauci has estimated that 25 percent to 50 percent of cases may be asymptomatic.
