This is nothing new! I was on a flight that landed in Tampa, FL, and we parked out in the middle of nowhere, where Health Dept folks boarded the plane, and took a family of five off the plane. We were given no explanation, asked to provide our contact info for the next 72 hours, etc.
I went to the airport manager who had zero knowledge of the boarding and removal. We called the Health Dept, and when I explained I had a five month pregnant wife, they finally broke down and told me the family removed had CHOLERA!
Fact is, our government does not give a sh*t about the wellbeing of USA citizens. Every day, more like Russia, people are completely expendable.
