It's important to keep an eye on the shift. What I mean is that "5 day isolation" is insufficient; it actually releases infected people into the population at the height of their infectiousness.
The CDC has rightly taken huge flack for their "5 day" policy, based not on science but on the demands of their real masters.
Enter the floated "1-day" policy. Suddenly, everyone is talking about how 5-day is much better than 1-day, not how 5-day is an absurd abdication of duty.
Watch the shift.
