Coronavirus 'rebound' cases after Paxlovid: What to know – The Washington Post

Sign in
President Biden is one of the latest patients to experience a “rebound” coronavirus infection following a course of Paxlovid, an antiviral used to treat people at risk of severe illness from covid-19.
Rebound cases, in which someone experiences symptoms or tests positive after completing the course of the medication and testing negative, have been described as rare, but some medical experts are saying they may be more common than previously thought.
Biden began his Paxlovid treatment shortly after testing positive. He emerged from isolation on Wednesday after he started testing negative, but the White House announced Saturday that he had again tested positive and was not experiencing symptoms.
Biden tests positive again for coronavirus after Paxlovid ‘rebound’
Here’s what to know about rebound cases of the coronavirus following Paxlovid treatment.
Vaccines: The CDC recommends that everyone age 5 and older get an updated covid booster shot designed to target both the original virus and the omicron variant. Here’s some guidance on when you should get the omicron booster and how vaccine efficacy could be affected by your prior infections.
Variants: Instead of a single new Greek letter variant, a group of immune-evading omicron spinoffs are popping up all over the world. Any dominant variant will likely knock out monoclonal antibodies, targeted drugs that can be used as a treatment or to protect immunocompromised people.
Tripledemic: Hospitals are overwhelmed by a combination of respiratory illnesses, staffing shortages and nursing home closures. And experts believe the problem will deteriorate further in coming months. Here’s how to tell the difference between RSV, the flu and covid-19.
Guidance: CDC guidelines have been confusing — if you get covid, here’s how to tell when you’re no longer contagious. We’ve also created a guide to help you decide when to keep wearing face coverings.
