CDC-HAN: COVID-19 Rebound After Paxlovid Treatment The CDC has issued a Health Advisory to provide an update on the potential for recurrence of COVID-19 or “COVID-19 rebound” after Paxlovid treatment. COVID-19 rebound has been reported to occur between 2 and 8 days after initial recovery and is characterized by a recurrence of COVID-19 symptoms OR a new positive viral test after having tested negative. A brief return of symptoms may be part of the natural history of SARS-CoV-2 infection in some persons, independent of treatment with Paxlovid and regardless of vaccination status. Available information suggests that persons treated with Paxlovid who experience COVID-19 rebound have had mild illness; there are no reports of severe disease. Please see the health advisory for recommendations for healthcare providers.
