Homegrove pattern you see everywhere - those countries that did well in the first wave in March/April (eg Czech, Israel) end up having nasty spikes later on - human complacency. Italy had awful first wave, and its second wave was slow to kick in. The UK, on the other hand, has had it nasty in each wave ffs.
