I've belatedly noticed that the Hong Kong Centre for Health Protection has an "EV Scan" page, updated weekly. The update is a PDF, in English and Chinese, that gives considerable information on diseases caused by enteroviruses. The updates are archived all the way back to 2008, making this an even more useful resource.
The scan also shows that Hong Kong had 1,363 HFMD cases in 2011, which sounds bad until you compare that number with the 5,025 cases in 2010.
