A quick comparison of the rate of H7N9 case climb over different 2-month periods...

While there has definitely been a lot of H7N9 human case activity centred around Guangdong province of late, but how does it compare with the 2013 H7N9 hotzones of Shanghai, Zhejiang province and Jiangsu province? 

This rough comparison of a 2-month period uses the same y-axis (50-case maximum) encompasses the most active periods of case announcements. It shows that the Guangdong province case tally has not risen to the same peak in the same period as the other 3 regions in 2013. With 2 new Guangdong cases announced this evening (my time) and a Shanghai case, all in males, it will be interesting to watch this ascent.

H7N9 cases now at 182, 52 (28.6%) fatal.
