[ WP ] Diseases ca n't be cured , only passed on to someone else . It 's common for those about to die from old age to act as recipients , allowing the young to live lives free from illness .

…We could n't stop the epidemic. 
 
 80 % of the world's population wiped out within the first decade. Within another five years, only 9 % of the population remained. There were no cures, only viruses. The lucky ones managed to pass on their virus to a new host before anyone realized they were infected; the rest were quarantined, and herded like cattle into containment areas in an attempt to stop the spread of illness to the rest of the population. It was a stopgap measure at best; once the government realized the diseased were beyond saving, they became death camps. 
 
 
 With too many bodies to bury and contagious corpses littering the land, the World Health Organization officially declared a state of emergency, and pleaded with ruling governments to implement drastic measures to prevent the complete annihilation of humanity. The problem was more than just disease, it was affecting every facet of living; less land meant less room to grow crops and livestock, and the drastic drop in both educated and able-bodied workers to disease left modern society barely able to function. Something had to be done, they said, and quickly. 
 
 
 They never announced it on the news, and they never asked for forgiveness. But everyone could tell, and nobody questioned it. The smell of napalm in the air was a small price to pay for saving humanity.
