FAO Interim Update On H7N9











#12,109


The FAO generally updates their H7N9 page about once a month during the winter, and less often during the summer.  Their last update was on January 4th, at which time only 23 cases had been reported during this 5th epidemic season - and at that time their next scheduled update was set for February 1st.

The news that, `Since the last update (4 January 2017), 106 new human cases have been reported in Jiangsu (52), Zhejiang (21), Guangdong (15), Anhui (6), Jiangxi (5), Shandong (2), Fujian (2), Hunan (1), Guizhou (1), and Shanghai (1).' has resulted in the FAO posting an interim update today.

Given the fluidity of the situation, today's update has dispensed with their standard practice of putting their `next update' date in the header.   I've only included some highlights, follow the link below for this data (and graphic) rich update.
