Influenza: does censorship increase control?

Recently, avian influenza has returned to public attention, by coincidence appearing at the same time in three different settings: a Hong Kong poultry market; a Shenzhen bus driver; and laboratories in the Wisconsin and the Netherlands. Though the timing of the events was coincidental, it made clear that 'avian influenza' is a viral object literally cultured by human labors, in the market or the petri dish. It also raised important questions about how these human labors contribute to increasing danger, security or preparedness.
