You forgot #6. Everybody else.
Epidemic quarantines are not a particularly good means of control, or really, there are far easier and more effective means of control than quarantines.
As far as epidemic-like control measures, there is only one international control means that applies to biological, chemical and nuclear scenarios. It was invoked by the Soviet Union a few times, and once in Italy. It amounts to building a fence around the area, optionally outprocessing everyone within, and abandoning the place.
The Italian incident, the “Seveso disaster”, is best known.

I’m not sure if the Soviets activated it after Chernobyl, as it was such a grand disaster that there was no need for international notification.
The problem with using a national epidemic as a means of control is that quarantines are under the control of doctors, who while they instantly have authority over the police and even military personnel, are focused on the disease, not the control measures. This is the case even when they are acting in their most authoritarian manner.
And this tends to fly in the face of political control, so even an ordinary person can tell the difference.
