Interesting. If no one is presenting symptoms, how would the caller know? As for how we'd find out, the MDs would probably test for smallpox antibodies...

People with the disease develop blisterlike lesions on their bodies. These turn into pustules - they are not hard to miss. Of course, prior to the blister-like lesions, you are infected and no one would know until the blisters form, making detection "by eyeballing it" difficult.

Nope. don't develop antibody till later in the course of the illness. ehre is no test for smallpox antigen (actual virus proteins ), diagnosis is still clinical. If they think this is a credible threat they will have to quaranteen everybody till incubation period is over.
