Oops! Cat is out of the bag. Most of us have complained that Covid isolation of 24 hours is too short. Now someone actually collected data. The MEDIAN time for Covid recovery is 20 DAYS! MEDIAN excludes all the LC cases (worst 22.3%). 50%, not 95% recovered in 20 days.

Bad news for all of us. Harvard researchers documented transmission of SARS-COV-2 from asymptomatic patient to new patient 4.45 hours after index patient left the room. Virus RNA sequences identical. Air turnover 6x per hour (6 hrs prior to outbreak)
1/Case study demonstrating remarkable longevity of airbone SARS-CoV-2.
Asymptomatic patient exited a room but lingering aerosols infected two others who entered much later: one who entered 1 hr & 45 min later, and a second who entered a whole 4 hrs, 45 min later!

I think I found a better N95 mask, the Moldex 4800 AirWave N95. I got it because I have an MRI scheduled, and this has no metal to fry me. I'm keeping it because it is the most breathable N95 I've found, and doesn't fog my glasses, so probably has a tighter seal than an Aura.

So you say, "I'll do 2 RAT tests". OK, you start with a positive PCR on day 0 (which you don't know about because you aren't doing PCRs), do 1 negative RAT on day 0, another negative RAT on day 2, then go to party, you are 49% chance of being infectious at the party. (3/6)

Fine. "I'll do 3 RAT tests over 96 hrs before party". Positive PCR day 0, 3 negative RATs on day 0, 2, 4. Stayed isolated for all 4 days before party. You are STILL 25% chance of being infectious at the party. (4/6)
