President Trump has been "symptom-free" from the coronavirus for over 24 hours, White House physician Sean Conley said in a Wednesday update.

The state of play: Conley's letter also says that Trump has not received or needed supplemental oxygen since his initial hospitalization and that lab tests on Monday showed the president has signs of coronavirus antibodies in his blood that were not present last Thursday.

Worth noting: The memo does not address some of the outstanding questions about Trump's health that Conley has avoided answering at press briefings.

  • It includes no information on what medications Trump is still taking. Some of the treatments Conley said the president had been prescribed require multiday courses.
  • It also includes no information about the timing of Trump's last negative test, which Conley refused to provide at a Monday briefing. Trump publicly announced that he tested positive early Friday morning.

The big picture: The CDC states that a person can be contagious for up to 10 days after coronavirus symptoms resolve. It also notes that it can take anywhere from one to three weeks after an infection for the body to create antibodies.

  • One of the experimental treatments given to the president was an antibody cocktail from Regeneron.
  • Preliminary data show that the patients most likely to benefit from the experimental cocktail had undetectable antibodies and were early in the course of the disease — a similar profile to Trump, a Regeneron spokesperson told NBC's Peter Alexander.
  • It "is likely that the second test is detecting REGN-COV2 antibodies," the spokesperson said, referencing signs of coronavirus antibodies in the president's blood.

A World Health Organization team of researchers arrived in Wuhan, China, Thursday ahead of their investigation into the origins of the COVID-19 pandemic.

Driving the news: Dominic Dwyer, a Sydney virologist based who's among the scientists on the visit, told the Australian Broadcasting Corporation they don't expect to find a "patient zero." "But we may have a much better indication of whether the virus truly started in Wuhan," he said.

Southern California's COVID outbreak is in a terrible place, and hospitals haven't even been hit with a wave of potential infections from Christmas and New Year's.

The big picture: Hospitalizations have stabilized, but public health officials say that's just from infections linked to Thanksgiving, the L.A. Times reports.
