Bio Terrorism Questions

I don't know if all of these occurrences are normal or not. Most of these articles indicate that such outbreaks are rare, if not previously know in terms of scale.

Something killing the catfish?

Deadly canine flu spreads in the U.S.

Study: 'Superbug' Germ Kills 3 in Chicago

Outbreak of horse, goat disease causing concern

Fungal disease poses threat to global wheat crop

Officials probe deer disease

Bass sickness strikes southeast Iowa lake

Disease kills thousands of trout

Diseased bighorn sheep in cross hairs

Think also of H5N1...

The question I have is how would we know the difference between natural viral outbreaks and those initiated by terrorist efforts?

Moreover, isn't it more likely that if you are going to try and spread a virus, you'd take the cocktail approach and see what takes?

This stuff could keep you awake at night...
