In and of itself the effects of the current incarnation of the swine flu may not be all you have to worry about.

Secondary infections, particularly infection with bacteria like MRSA, that are pretty much immune to all the common antibiotics and strains like KPC that may soon be immune to all the less common antibiotics if we don't play our cards right, may play the grim reaper as the relatively benign effects of the swine flu holds you immune defense system down. Even your garden variety seasonal flu can play that part. Even more likely if you are immune compromised already.

The young, old, those with chronic conditions like AIDS and those taking corticosteroids may start with a strike against them.
