Still waiting for the drop in reported cases since the authorities began closing markets. Exposure to live poultry seems to driving the outbreaks, but the number of infections is greater than in the period preceding this report (61 cases).
Thanks for posting, arirish - hopefully the next update shows the downward trend we should be seeing in the wake of the closures.

I'd like to know the percentages of urban vs rural cases. If it has moved out of the cities and into the back yard flocks, closing the markets might not slow it down much! They didn't shut down the markets until the middle of this reporting period so hopefully you're spot on. Guess we'll know more in a week or so.

Great question. That was where H5N1 flourished in Indonesia - it wasn't commercial flocks that exposed and sickened humans. It was families raising their own birds in small numbers.

Reading through this FAO update, it looks like Jiangxi Province is closing markets for short periods (two weeks or less) and only in affected cities, and Guangdong is banning the import of live poultry and closing two affected markets for three days (too late...). I guess we probably shouldn't expect that drop in cases if they're going to continue handling this outbreak in such a half-assed way
