Two separate analyses of studies and trials suggest that COVID-19 rebound is not linked to Paxlovid or other antiviral drugs.

The findings contradict other studies that indicated a higher frequency of COVID-19 rebound among people treated with Paxlovid (nirmatrelvir/ritonavir, Pfizer).

Rebound is typically described as a recurrence of symptoms after recovery or a new positive viral test after testing negative, Pragna Patel, MD, MPH, DRM&H, chief medical officer in the Coronavirus and Other Respiratory Viruses division of the CDCs National Center for Immunization and Respiratory Diseases, told Healio. We found that there was no consistent association between treatment for COVID-19 and COVID-19 rebound. Also, we found that COVID-19 rebound can happen among patients whether they received antiviral treatments or not.

It was the top story in infectious disease last week.
