I was listening to a professor in virology talking on the TV this mornng. He said :-
1. You can not get bird flu easily. Even if you eat birds that had the virus, it would have been completely destroyed in the cooking process. (Unlike CJD, where the prion responsible is impossible to kill in the cooking process).
2. Only people who are in very close contact with infected birds are at high risk. Plucking infected birds (when the virus would be highly airborne) would carry the highest risk
There is no point in wearing masks if you are not in close contact with infected birds. Now if humans were to have it then it would be necessary, but then they would be nursed in isolation units, which I believe the Dept of Health have on standby.
