So here’s what happened. A new strain arose that was more infectious; that means that its R number is higher. Because overall infection prevalence was rising a short, weak lockdown was ordered, which reduced the average R – that is, R for all strains together – to about 0.8, so overall infection prevalence fell. But R for the new strain was higher, so it remained above 1, so while the original strain got reduced, the new strain increased. When the “lockdown” ended, the new strain had been given a head start.

Brilliant, eh? Looks like France might have closed its borders to trucks from the UK:

“We can’t lock down it’ll destroy the economy!”
