H7N9 by area of case acquisition...

This is another way of looking at the sites of origin of avian influenza A(H7N9) virus cases in southern and eastern China. After adding in the most recent 7-cases today, Guangdong province now comprises 9.9% of cases. 

Females dropped a little from yesterdays post, but remain a more frequent presence than we saw in 2013 or overall on average numbers.

I know if I go to bed now, the next batch of cases may well arrive but such is life in the southern hemisphere.

There is talk of more live bird markets closing soon. Given that most cases still list some contact with poultry (feels like there might be more without contact in recent notifications?), more closures cannot come soon enough in my opinion. 

Whilst these numbers are small given the population sizes involved and can in no way be confused with a seasonal influenza epidemic, they are gaining on that "other" bird flu, H5N1, at an increasing rate.
