Overview
COVID-19 rebound refers to a recurrence of symptoms or a positive test after an initial recovery from a COVID-19 infection. It has been noted in some people who took the antiviral drug Paxlovid, though it can occur without treatment.
Symptoms
Symptoms are usually mild and similar to the initial illness, including sore throat, cough, headache, and fever.
Causes
The exact cause is not fully understood, but it is not a sign of treatment failure. It may be a normal part of the body's immune response.
Treatment
Rebound symptoms are typically mild and don't require additional treatment. It is important to isolate again to prevent transmission.
When to See a Doctor
If symptoms are severe or you are in a high-risk group, consult your doctor.
