Rebounds: I’ve tracked more than 5k infections in the film and TV industry over the past 2 years. Roughly 50% of people taking Paxlovid rebound ~3 days after finishing the course. I’ve only had 1 rebound in people who don’t take Paxlovid. Daily testing. Cont.

People who rebound on Paxlovid tend to clear on antigen tests very quickly (~4-5 days). However the infection comes back, often symptomatic and infectious - confirmed transmission. I have NOT had anyone take two course of Paxlovid.

In the last 2 years, I’ve had only one person who was infected while flying across the country. In the last month, ~5% of the crew I work with have been infected while in transit. Dropping of the international testing requirement is going to compound that problem. Today, I was arranging private transport back to the USA for a family infected and stuck overseas. With today’s breaking news of no testing requirement, they are going to wait until Sunday and fly commercial. This is such a great plan!

I am baffled at CDC’s decision to shorten isolation. Here are tests from the same person: day 0 (3 days after exposure) and day 8. The person still has a huge amount of virus in their nose 8 days after testing positive. n=59. Quickest clearance 6 days, longest (vacc) 8.5 days. To put this into context. I oversee the testing of 1000’s of people each week in workplace surveillance programs. Some people we test daily, others once a week. Millions of tests over the past 18 months. As we do not want to have workplace transmission, we ensure that (next)

Hmmm. Boarding a flight for an urgent work trip. Thought I might look at the amount of recycled air inside the plane. Steadily increased from 600ppm to 1300ppm as the door closed. Being on the ground is the worst air.... supposedly. Let’s see. Backed away from gate (disconnected from APU.
