Surprisingly slow rate of increase. Testing here has not been very proactive, to be sure. But there has been a sharp drop in seasonal flu this year compared to usual years, suggesting that less is being transmitted in general, so I have no doubt that some of this is "real."
I live in Japan, and have my theories but to be honest, even those of us living here are a bit baffled by this. Are we waiting for the storm to hit, or has Japanese society hit on "something" which limits the virus's spread?
