Most people who become infected return to normal health. However, there is still much to learn about the possible long-term health effects and why some people have symptoms that last well after their initial diagnosis. Common lingering symptoms include fatigue, shortness of breath, cough, joint and chest pain as well as body aches. Lack of clear thinking known as “brain fog,” headaches, fever, heart palpitations, loss of taste and/or smell, rash and hair loss have also been described.
