What exactly would an assymetrical biological attack look like?

It would appear initially as a few cases of unusual disease, probably respiratory. Initial cases would eventually succumb in a few days due to lack of diagnostics.

The index cases are then identified and ring quarantine occurs in order to limit contagion.

IMHO, ring quarantine is an idiotic idea and these reports prove so. Air travel is so easy that movement is a piece of cake. Unless you start limiting movement of people, you can't limit spread of the disease.
