which apocalyptic senario do you fear the worst?

[Moristans]

I think plague pandemics are a lot less likely today. Human hygiene has come a long way, as has our ability to deal with pests that would carry it plus our ability to analyze the disease and come up with a cure or treatment for it.

Hospitalizations related to a potentially deadly, antibiotic-resistant “superbug” more than doubled between 1999 and 2005, soaring from 127,000 to nearly 280,000, according to a new study co-authored by a University of Florida researcher.

Ironically, Human hygiene might ultimately be the cause of the next pandemic. Eventually, we are going to run out of ways or resources to keep re-making Penicillin so that bacterial strains aren't resistant to anti-biotics.

Or, alternatively, viruses mutate. That's the nature of viruses. Eventually one will mutate into something that will be a pandemic.
