Countries like Japan and South Korea got hit again as well, but have wrestled it down a second time, with infections trending the right way.
The waves of a pandemic are interesting, because AFAIK there is nothing about the virus itself which would lead to this effect, I assume it must be driven almost entirely by human behaviour...I'm tempted to try and model this, I am curious about what it is that humans are doing that causes this, because in many (most?) cases, the second spike is far far larger than the initial.
