I'm not aware that the HK Government is hiding the truth. If you go to their website here:
http://www.info.gov.hk/dh/ap.htm
you will find all osrts of data and advice.
Including the fact that 3000 people die of pneumonia in HK each year.
What it won't tell you is that HK Chinese are one of the most over-medicated populations in the world - the response to every little bug being a bag full of anti-biotics, and the result being mass hypochondria and pretty feeble immune systems in general.
40,000 gwailos (and a few Chinese) had a great time at the weekend shouting at each other drinking beer and undoubtedly exchanging a lot of respiratory fluids. We're not all going to die. In fact I'd be surprised if there is anything much more than a few severe hangovers going around. (Oh and a few sore throats/failing voices from all the shouting)
And England won AGAIN
