The number of human cases of avian 'flu world-wide, attributable to wild
birds, is currently put at zero. In assessing risk, this would be the
figure, suitably scaled, that would be used to calculate human risk.

Multiplication of the numerator of a fraction by zero does not require too
much knowledge of Arithmetic to work out. An 'O' grade should be enough.



If you read through

http://www.who.int/mediacentre/factsheets/avian_influenza/en/

you will see that the main risk factor speculated on is contact with
infected birds, dead or alive. It matters not whether the infected birds are
'wild' or 'domestic'.
