SNAPDATE: H7N9 by map...

With the latest numbers out from Hong Kong's Centre for Health Protection, Week 10 marks the second week of around a dozen human spillover cases - likley to be poultry to human infections.

While the number of cases at each geographic location within China is small given the millions living in each region, this week's cases are spread across 10 provinces or municipalities. A huge area. 

Guangxi province is adjacent to Vietnam. It's always worth remembering that an outbreak anywhere can turn into a threat everywhere

From these numbers, there is no obvious escalation of human cases to suggest anything has changed in the way H7N9 infections are acquired; they remain relatively rare and from animal-to-human close contact.

While the cases are still coming, the totals (see weekly and daily bars below) shows a levelling off - at last suggesting a slowing of this season's epidemic. But stay tuned.
