President Donald J. Trump is being flown to Walter Reed National Military Medical Center as he battles the coronavirus.

The president announced early Friday morning that he and First Lady Melania Trump both tested positive for COVID-19.

The Trumps were tested hours earlier and had been awaiting results while quarantining since it was reported on Thursday that Hope Hicks, a senior White House aide, had tested positive. Hicks had traveled with the president on multiple occasions this week.

It was not immediately clear how or when Hicks or the Trumps were exposed to the virus. It can take days after exposure before a test would yield a positive result.

Trump’s White House physician on Friday afternoon announced the president “as a precautionary measure… received a single 8 gram dose of Regeneron’s polyclonal antibody cocktail.”

This is still an experimental drug cocktail that has not yet been approved by the FDA, even for emergency use. The company, however, can grant its use on a “compassionate” basis.

Additionally, as of Friday afternoon, Trump had been taking a daily dosage of aspirin, Vitamin D, zinc, melatonin and famotidine. The physician detailed that Trump was experiencing fatigue but in “good spirits.”

In a brief announcement released shortly after 4:00 p.m. CST, the White House press secretary said Trump continues to have “mild symptoms.” Those symptoms reportedly include a mild cough and headache.

“Out of an abundance of caution, and at the recommendation of his physician and medical experts, the President will be working from the presidential offices at Walter Reed for the next few days,” she explained.

Dr. Jeanne Marrazzo, the director of the division of infectious diseases at the University of Alabama at Birmingham (UAB) and a 2020 Yellowhammer Woman of Impact, told CNN that results of Regeneron’s clinical trials thus far appear “very promising.”

“What I think is fascinating is that it shows that antibodies really matter, and the antibody to the spike protein was really helpful, particularly when people made the antibodies themselves,” she advised. “Whether it’s antibody therapy or vaccine that target these proteins, it sounds like we are on the right track. I think that’s really encouraging.”

Vice President Mike Pence on Friday morning tested negative for COVID-19.
