Ask older relatives about quarantine for polio, measles, scarlet fever, or similar diseases. Most of us under 40 years of age have never had to quarantine or even heard of anyone we know needing to quarantine (during our lifetimes) prior to covid. My mother had to scarlet fever, my grandmother had measles and polio, and I don’t remember how many communicable diseases my great-grandmother had. They also quarantined if someone else in the household had something (my grandmother never caught scarlet fever, but the whole household quarantined when my mother had it).
The opposite happened when I was a child. There were chicken pox parties! As a nation, we had successfully eradicated community spread of the worst diseases through vaccination. Now, we have vaccines even for chicken pox. Naturally, our society has forgotten the need to contain disease (which is how the measles and smallpox outbreaks happened), vaccination waned as society forgot. We’re at a high point for vaccination again, and we’ve forgotten that everything stops when it comes to life and death.
Covid has a 2-14 day incubation. 2 weeks of quarantine is warranted. Quarantine is simple: nothing out, nobody in or out. You can have food delivered to your porch. That’s it.
