The memo states that Trump meets criteria from the US Centers for Disease Control and Prevention to end the isolation, but does not say Trump has received a negative coronavirus test since the first test positive for the virus last week. However, this is not a criterion for removing isolation, according to the CDC.
“This afternoon I am pleased to announce that in addition to the President meeting the CDC criteria for the safe discontinuation of isolation, the COVID PCR sample this morning demonstrates, from the currently recognized standards, that it is no longer considered a transmission risk. to others, “reads Conley in part.
Conley wrote that Trump is 10 days away from the onset of symptoms, was free of fever for “more than 24 hours” and after diagnostic tests, “there is no evidence of active reproduction of the virus.”
The president’s doctor said Trump had undetectable “subgenomic mRNA.” These are molecules that are produced when viruses reproduce. Their absence may indicate that Trump is no longer eliminating a live virus.
But Conley did not fully explain what “advanced diagnostic tests” the President had taken. For example, it did not disclose whether the so-called viral culture was performed. This is the process by which scientists try to infect living cells to see if there is an active virus.
Under the guidance of the CDC, research has shown that PCR tests can still pick up pieces of genetic material from the virus long after someone has recovered. But these people are unlikely to be infectious 10-20 days after the onset of symptoms. Although PCR tests may come back positive, patients do not tend to be infectious after this 10-20 day window has passed, according to research.
The latest revelation from Conley comes as Trump prepares to return to the campaign trail after being neglected in the middle of his fight with the virus. It is likely to raise additional questions about the President’s health as officials continue to make cautious statements as the campaign draws to a close.
Officials – including Conley – have not yet revealed when the president was last tested negative before his positive test last week, which would indicate when he was contagious and how much.
“I think the secret for me was that I got there very early,” he told the network’s medical assistant. Marc Siegel.
Trump had received an immediate dose of experimental monoclonal antibody therapy at the White House, and was then treated with a drug injected with the antiviral drug remdesivir and the steroid dexamethasone during his hospital stay. He was also given supplemental oxygen, Conley said earlier.
