Those look interesting, though instead of it being fifteen years how about twenty? This way we can have a high age range for characters born after the event and thus producing the 'mutations' in the viruses that don't kill them or cause their eventual death, but rather giving them their supernatural powers.

Also to add to the plot, how about trying to gather the people together again to help one another to find cures for those that can be killed by these viruses? And of course running away from those that would see those with mutations as merely test subjects and not as human beings.
