White House chief of staff Mark Meadows has told the reporters that US President Donald Trump's vitals over the last 24 hours were very concerning.
"The president's vitals over the last 24 hours were very concerning and the next 48 hours will be critical in terms of his care. We're still not on a clear path to a full recovery," he told media, Reuters reports.
Earlier, a White House team of doctors said on Saturday morning that Trump's condition was improving and that he was already talking about returning to the White House. One doctor said Trump told them, 'I feel like I could walk out of here today.'
However, Meadows altered his tone hours later, telling Reuters that Trump was doing "very well" and that "doctors are very pleased with his vital signs."
Meadows did not clarify the discrepancy in his comments. A Trump adviser who spoke on condition of anonymity said the president was not happy to learn of Meadows' initial remarks.
Trump had received a first dose of a five-day course of Remdesivir, an intravenous antiviral drug sold by Gilead Sciences Inc that has been shown to shorten hospital stays.
He is also taking an experimental treatment, Regeneron's REGN-COV2, one of several experimental Covid-19 drugs known as monoclonal antibodies, as well as zinc, Vitamin D, famotidine, melatonin and aspirin.
The US president is at high risk because of his age and weight. He has remained in apparent good health during his time in office but is not known to exercise regularly or to follow a healthy diet.
Earlier on October 2, US President Donald Trump and First Lady Melania Trump tested positive for Covid-19.
