Hi, contact tracer here. Based on publicly available knowledge, I'm going to attempt to trace this WH outbreak, working off the assumption that there was a positive case at the Rose Garden SCOTUS ceremony. 1/10

Ceremony was held 9/26.  Just SOME of the people in attendance included:  Mike Lee, Mike Crapo, Ben Sasse, Thomas Tillis, Josh Hawley, Chris Christie, Mark Meadows, Hope Hicks, Wililam Barr and more. 2/10

COVID has an incubation period of 2-14 days, with an average of 5 days.  Hope Hicks started showing symptoms on Wednesday 10/7.. DAY FIVE.  You can spread the virus 2 days before you start to feel unwell. The day you first show symptoms is when you are most contagious. 3/10

What was Hope Hicks doing on her most contagious day? Flying in AirForce One, Marine One, and at a Trump rally. In the two days prior, while she was likely infectious, she was doing debate prep and at the debate without a mask. 4/10

Worth noting: it's impossible to say that Hope Hicks is the only spreader. There may be many. 5/10

This means that anyone in contact with Hope Hicks or anyone part of this possible cluster could test positive through October 10th from this single event alone.  No one who attended the SCOTUS Rose Garden ceremony is out of the woods until Oct 10 6/10

Contact tracers would ask anyone who had close contact with a case to quarantine for 14 days to break the various chains of transmission.  People who should quarantine based on what we know include:  probably anyone at that Rose Garden ceremony. 7/10

The president tested positive on Thursday, Oct. 1.  Anyone who has been within six feet of him for 10 mins or more since 9/30 , even with a mask, should quarantine for 14 days. 8/10

Question - when was the last in-person interaction between Trump and Pence?  In the name of public health, should he be debating anyone in person next week? 9/10

In summary, wear a mask, wash your hands, keep your distance from everyone as much as possible.  A little common sense goes a long way. 10/10

Of course, I have made a fair number of assumptions here, including the origin event. But it does demonstrate how quickly an airborne pathogen can spread, and why it's so critical to wear masks.
