Quarantine should have happened with this guy when he went to the hospital the first time. From Liberia, with a fever, should have caused the triage nurse to immediately isolate him in a negative pressure room if possible, and no one else approach him without full protective gear.
Lock down the waiting room, and get ready to isolate and monitor those there.
Even after it was known that he had Ebola, people without protective gear were trapsing in and out of the apartment before it was sanitized. It’s just been a total screw up from the git go.
Quarantine used to mean no one in or out. Not well we make exceptions when we want to.
In my experience, most people don’t have the vaguest notion of how science works. I once saw a woman who had cut herself on a bus being offered a bottle of water to clean it with—a bottle that had already been drunk out of.
People have not been taught science. It’s too hard.
Now with this creepy disease that you can apparently get from very minor secondhand contact, it is hopeless. The average schmo will never catch on.
As for exponential growth of anything, forget it.
