Some clarifications and thoughts:
1. At this moment the virus spreads only from birds to human (and possibly the other way). I assume infection of H7N9 can occur by eating poultry that
had been infected by the virus and wasn't cooked enought and therefore bear a risk for infection (explanation to why people got sick despite of not
contacting poultry directly) .
2. The small number of infections in poultry means that bird-to-bird transmission is low (it seems the virus doesn't adapt very rapidly at least in
birds, in humans? we don't know yet).
3. This low number of infected birds doesn't mean that this virus cannot infect well humans.
4. The region where the virus first originated in humans in china adequates to bird migration routes of birds coming from New Zealand and Australia.
These wild birds were heading north (northern coast of Russia mainly) for breeding. It's a matter of time until the virus spreads to human in other
places around the world. Even if this virus dissapears suddenly, it will apear very soon again my guess.
