President Donald Trump appears healthy just one week after testing positive for COVID-19, a top government infectious disease expert said Thursday.
"He certainly looks good and apparently feels good," Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, who is not involved in Trump's care, said during a virtual appearance on MSNBC after being asked to analyze the president from afar.
"One of the issues that we all have to be aware—and his physicians are aware of this—that the history of COVID-19 is that you could look and feel like you’re doing reasonably well, and after a couple of days you could have a downturn, namely have a reversal. That’s possible," he added. "The chances of that happening, I don’t know. As good as he looks, I don’t think that’s going to happen, but I don’t know. But you have to be heads-up that it might happen."
Dr. Sean Conley, Trump's doctor, said in a memorandum on Oct. 8 that Trump has "responded extremely well to treatment."
Trump said on Fox Business on Thursday, in his first interview since his positive test, that he felt well enough to do a rally earlier than that.
"I wanted to do one last night. But I think I'm better to a point that I feel better than I did, you know, I jokingly said 20 years ago. I feel perfect. There's nothing wrong," he said.
Preliminary data from testing of the cocktail are favorable but full clinical trials are required to prove it works, Fauci said in his interview.
"I think it’s a reasonably good chance that the antibody that he received, the Regeneron antibody, made a significant difference in a positive way in his course," he said, adding later, "There is a reasonably good chance that that, in fact, made him much better."
The Centers for Disease Control and Prevention (CDC) recommends COVID-19 patients wait 10 days from symptom onset before going out and about, as it takes that long in some cases to become non-infectious. Another recommendation is to test negative twice across 24 hours before leaving isolation.
"So if the president goes 10 days without symptoms, and they do the tests that we were talking about, then you could make the assumption, based on good science, that he is not infected," Fauci said. "But you have to wait and make sure you go through those particular benchmarks that are delineated in the CDC guidelines."
