The 81-year old Fauci first contracted coronavirus two weeks ago on the 15th of June. Following that, Fauci's physicians advised him to take Pfizer's antiviral medicine Paxlovid due to his age, causing him to develop complications.
After having completed his five-day treatment that included Paxlovid, Fauci tested negative for coronavirus three consecutive days and on the final day Fauci tested positive for coronavirus again.
“After I finished the five days of Paxlovid, I reverted to negative on an antigen test for three days in a row,” Fauci told reporters on Tuesday. “And four days later, to make sure I was 100% certain, I took a test myself once more. I was back on the positive side.”
The CDC reported that health professionals across the nation keep an eye on an “seemingly rare, but increasingly reported phenomenon” known as the Paxlovid rebound that occurred last month.
“It was sort of what people are referring to as a Paxlovid rebound,” Fauci explained.
As ABC News explained:
The phenomenon of rebounding that is described as a recurrence in COVID-19 symptoms, or the emergence of a positive virus test after having been negative, was found to be present within two to eight days following the initial recovery. The brief return of symptoms associated with COVID-19 could constitute a part of “natural history” of the virus, as officials stated and could occur in certain people regardless of treatment with Paxlovid and vaccination.
Fauci said that his coronavirus second round following his Paxlovid return proved to be “much worse than in the first go around.”
The following day, the doctor stated that it was the fourth day of his second treatment of five days with Paxlovid.
“And I am fortunate to be feeling fairly well. That's right, I'm certainly not totally free of indications, yet I definitely do not feel sickly,” Fauci said.
Although Paxlovid is approved by the United States for individuals with mild or moderate symptoms of the virus, there's no evidence that another treatment of Paxlovid is necessary as per the CDC.
