The retrovirus mutates
Into an airborne pandemic
Cytopathic effects on the host's cellular structure
Extensive irreparable damage
Immunity is an impossibility

Virulence
Metaphorical Luftwaffe takes to the skies
Nature's genocide
The damage done to man
Will never match what man has done

Quarantine failing
Breath it in

The aftermath
Heaps of human carnage
Corpses litter the landscape like weeds
Dandelions in spring
