I don't ask for this kind of help often but a high school buddy

18. Actually in my post I state the first step was testing

After people tested negative they were admitted and required to be masked, social distancing at an outdoor event was put in place and disinfecting was performed between speakers. All of the steps taken in totality created a safe environment for the Inauguration of President Biden

In the Trump Whitehouse, people would use the Abbott rapid test, which is not as reliable as PCR, one once they cleared they would not social distance, not mask and I never saw disenfecting going on. See the difference of the two tests below

Antigen test (frequently referred to as a rapid test). This test detects protein fragments specific to the Coronavirus. It can be done in a clinic, doctor’s office, or hospital. Turnaround time for results is usually very quick and in some cases, results can be reported within 15 minutes.

PCR test. PCR testing is considered the “gold standard” in SARS-CoV-2 detection. This test actually detects RNA (or genetic material) that is specific to the virus and can detect the virus within days of infection, even those who have no symptoms. The test can be done in a clinic, hospital, or even in your car. Turnaround time is longer, generally in the 2-3 day range but results can be in as little as 24 hours. When demand is high, results can take a week or longer.
