President Biden examined constructive for the coronavirus once more on Saturday morning, changing into the newest instance of a rebound case after taking the Paxlovid remedy that has in any other case been credited with broadly spectacular ends in combating the virus and suppressing its worst results.
“The president has skilled no re-emergence of signs, and continues to really feel fairly nicely,” Dr. Kevin C. O’Connor, the White Home doctor, stated in a memo launched by the press workplace. “This being the case, there isn’t any cause to reinitiate remedy at the moment, however we’ll clearly proceed shut commentary.”
The “‘rebound’ positivity,” as Dr. O’Connor termed it, meant that Mr. Biden was pressured to renew “strict isolation procedures” in step with medical recommendation. The White Home introduced that the president would now not journey to his house in Wilmington, Del., on Sunday as deliberate nor make a scheduled go to to Michigan on Tuesday to advertise newly handed laws supporting the home semiconductor trade.
Mr. Biden performed down the event. “Of us, as we speak I examined constructive for COVID once more,” he wrote on Twitter. “This occurs with a small minority of parents. I’ve acquired no signs however I’m going to isolate for the security of everybody round me. I’m nonetheless at work, and will likely be again on the highway quickly.”
The White Home later posted a video of the president on the Truman Balcony together with his canine Commander and he appeared nicely. “I’m feeling nice,” he stated. “All the things’s good.”
Mr. Biden first examined constructive for Covid-19 on July 21 and skilled a sore throat, runny nostril, cough, physique aches and fatigue. After 5 days of isolation, he examined damaging on Tuesday night and returned to the Oval Workplace on Wednesday, declaring that his comparatively delicate case demonstrated how a lot progress had been made in combating the virus that has killed multiple million People.
However medical doctors have been looking ahead to indicators of a rebound case and made positive to maintain testing him each day. He examined damaging on Wednesday, Thursday and Friday earlier than receiving a constructive antigen end result on Saturday morning.
Paxlovid rebound has grow to be a supply of debate throughout the scientific neighborhood and amongst Covid sufferers. Preliminary medical research of the drug, which is made by Pfizer, steered that solely about 1 p.c to 2 p.c of these handled with Paxlovid skilled signs once more. A examine revealed in June that has not but been peer-reviewed discovered that of 13,644 adults, about 5 p.c examined constructive once more inside 30 days and 6 p.c skilled signs once more.
However the anecdotal accounts of Paxlovid rebound — together with a case involving Dr. Anthony S. Fauci, the president’s chief medical adviser — have echoed extensively, inflicting many to wonder if the reported knowledge was nonetheless correct as the brand new and rather more contagious BA.5 subvariant sweeps by way of communities and reinfects even sufferers who just lately recovered from Covid-19.
“I believe this was predictable,” Dr. Jonathan Reiner, a outstanding heart specialist and professor of drugs and surgical procedure at George Washington College Hospital, wrote on Twitter on Saturday after the president’s constructive check was disclosed. He added that “the prior knowledge suggesting ‘rebound’ Paxlovid positivity within the low single digits is outdated” and that the true quantity was probably considerably increased.
The Biden Presidency
With midterm elections looming, right here’s the place President Biden stands.
Both method, specialists confused that Paxlovid had been notably profitable in stopping extra extreme Covid-19 diseases and hospitalizations. And a Facilities for Illness Management and Prevention examine revealed in June reported that signs from a rebound tended to be milder than through the major an infection and unlikely to result in hospitalization.
“Whereas we proceed to watch real-world knowledge, we stay very assured within the remedy’s effectiveness at stopping extreme outcomes from Covid-19,” Amy Rose, a Pfizer spokeswoman, stated in an announcement on Saturday.
The C.D.C. issued an emergency well being advisory in Might that stated folks experiencing a rebound case “ought to restart isolation and isolate once more” for at the least 5 days, reflecting the company’s common isolation suggestions for folks contaminated with the virus. The advisory additionally stated that rebounding didn’t signify reinfection with the virus or resistance to Paxlovid.
Dr. Ashish Ok. Jha, the White Home’s Covid-19 response coordinator, informed reporters when Mr. Biden first examined constructive that by Twitter, “it seems like everyone has rebound, however it turns on the market’s really medical knowledge” suggesting in any other case. Furthermore, he stated, “Paxlovid is working rather well at stopping critical sickness, rebound or no rebound, and that’s why he was supplied it, and that’s why the president took it.”
Dr. Paul G. Auwaerter, the medical director within the infectious ailments division on the Johns Hopkins College College of Drugs, stated it was unlikely that Mr. Biden, who has been absolutely vaccinated and boosted twice, would grow to be critically ailing. He added that scientists have been working to elucidate why some folks expertise a rebound of the virus.
Amongst his Covid-19 sufferers experiencing a rebound case, Dr. Auwaerter stated, lots of them have had the current Omicron subvariants. None has been hospitalized whereas rebounding. These extremely infectious and vaccine-evasive types of the virus, he added, could cause folks to check constructive for longer.
Taking the drug, Dr. Auwaerter stated, could possibly be like “transferring the purpose posts” in the middle of an an infection, suppressing the virus however not clearing it fully. Nonetheless, he stated, high-risk folks ought to “completely” nonetheless take the medicine.
Dr. John P. Moore, a virologist at Weill Cornell Drugs, stated researchers have been nonetheless missing correlations between age, threat elements or vaccination standing. “I haven’t heard anybody give you a definitive trigger,” he stated. “He’s simply the unfortunate man within the one out of 20. It’s only a numbers recreation.”
Dr. Moore stated that if knowledge may help such a transfer, federal regulators would possibly wish to contemplate permitting an extended course of the drug, to definitively rid the physique of the virus. “The only factor could be to return on the drug for longer,” he stated.
Mr. Biden’s rebound case will complicate his effort to show his sickness right into a constructive story. Because the oldest president within the nation’s historical past, Mr. Biden, 79, has been keen to indicate that he stays match, particularly as he forecasts plans to run for a second time period in 2024. He continued to work from the White Home residence throughout his first isolation, showing by video earlier than a number of teams, after which made a triumphal return to work in particular person on Wednesday.
As an alternative of the narrative of beating the virus, nonetheless, the president’s rebound case reinforces the disagreeable actuality that the pandemic refuses to go away. Though the dying toll has fallen dramatically, Covid-19 stays a reality of life for People, a few of whom have been contaminated a number of occasions.
Mr. Biden’s new constructive check can also increase questions on his constancy to precautions in opposition to infecting others after returning to the workplace. Aides stated he would put on a masks whereas with others, however in each public look he made since Wednesday, his face remained uncovered.
Aides stated that he was socially distant from others and that he was cautious to keep away from exposing aides, Secret Service brokers and members of the family employees. The White Home Medical Unit discovered that 17 folks had been in shut contact with Mr. Biden earlier than his preliminary constructive check, however as of Wednesday none had examined constructive.
Whereas the president didn’t put on a masks within the video on Saturday, a photograph launched by the White Home confirmed him sporting one as he signed a catastrophe declaration responding to flooding in Kentucky.
Dr. Auwaerter stated Mr. Biden may not have put others at nice threat in the previous few days even with out sporting a masks, since he was being examined for the virus commonly and was testing damaging. For these not testing as commonly, he stated, it could be prudent to proceed sporting a tightfitting and high-quality masks, notably round high-risk folks, due to how infectious Omicron subvariants might be.
However the brand new constructive check will even set again Mr. Biden’s efforts to get again on the highway to advertise his agenda and marketing campaign for Democrats dealing with an uphill wrestle to maintain management of each homes of Congress on this fall’s midterm elections.
The president, whose approval ranking stood at solely 33 p.c in a New York Occasions/Siena Faculty ballot in July, has been described as desirous to journey the nation after a spate of international journeys, however the renewed isolation will delay that additional.
