LOS ANGELES (KABC) -- Over the past few days, President Donald Trump has had meetings, a fundraiser and a rally, raising the question of how many people were exposed or even infected by COVID-19.
There's a mad dash to track anyone who has come in direct contact with Trump over the last week or so to get tested for the coronavirus. The problem? It's a really long list because Trump has been full steam ahead campaigning and holding events in the middle of a pandemic.
That makes contact tracing nearly impossible.
"It's hard to actually get our heads around the number of people that could have been exposed to the president, and I think the White House is trying really hard to identify everyone in his orbit," said MaryAlice Parks, deputy political director at ABC News. "But we're talking about dozens of people who are in regular contact with the commander in chief. Secret Service, local police, his staff, residence staff."
"Testing is a very important part of an infection control strategy, but testing alone is not an infection control strategy," said Dr. Michael Ben-Aderet, associate director epidemiology at Cedars-Sinai. "Even if a test is negative on day five, it doesn't mean that you're not at risk on day nine or 10."
Below is a review of the president's activities leading up to his COVID-19 diagnosis.
Saturday - Sept. 26
Last Saturday, Trump announced the nomination of judge Amy Coney Barrett to the Supreme Court, with a few hundred people in attendance, most not wearing masks. Sen. Mike Lee of Utah was seen at the event hugging attendees, he's now tested positive along with Notre Dame president John Jenkins. First lady Melania Trump was also at that event. The thousands in attendance at Trump's campaign rally that night in Pennsylvania have been urged to get tested if feeling sick.
