Have heard that from more than one place. If the first part of that comment was an accepted best odds probability, and the government was committed to it, then it's hard to understand why pressure to change has influenced government so quickly. Maybe politics still rules as much as mathematics.
In any case it looks obvious that test, test, test with social isolation is the most favored expert recommendation as best practice.
