Some coronavirus-positive patients who have completed treatment of the anti-COVID drug Paxlovid are rebounding into illness, and experts are urging people to be cautious if they develop COVID-like symptoms again and become infectious.
Los Angeles County Public Health Director Barbara Ferrer said post-Paxlovid COVID-19 relapses are "real."
"They've happened in a significant enough number that they've been noticed by lots of folks in lots of different places," she said.
Among those observing the rebound was Dr. Paul Sax, an infectious disease expert at Harvard Medical School, who recounted in a recent blog post how a patient with COVID-19 rapidly recovered after taking Paxlovid but a week later called him back saying she'd relapsed. Although the symptoms weren't as bad as her initial illness, rapid test results showed she was "clearly positive again."
