Most of the spending is going to disaster preparedness, which is available for ANY disaster, not just public health. That would be stocpiling personal protective equipment for health care workers, more patient respirators (most of which, in this country, are already at use at any given time) extra poultry testing to monitor wild bird migration vectors for H5N1, coordination of various agencies which would be involved in response to public health event, stockpiling of anti-influenza drugs and monitoring of their effectiveness, response teams which go to outbreak areas to assess the transmissibility of the virus in each area, stuff like that.
Additionally, there are research dollars being spent on changes in the H5N1 viruses to determine if it is becoming more or less transmissible, etc.
You may not appreciate that, but it is vital. In addition to H5N1, readiness training and exercises are transferrable to other potential biowar threats.
I can appreciate preparedness, but I don't think we need more billions to do it. Especially if those billions have any possibility of leaving this country and going to another country in a "stop it at the source" kind of thing.
We should have plenty of $ resources under Homeland Security.
