In the spring of 1985, a strain of HIV emerges that is easily-
communicable and airborne. Not an STD anymore, but a disease that is
as easily spread as a cold or flu.
What happens--how does history turn out from spring 1985-Present?
If it is that easily spread but still fatal then the big cities would become
very unhealthy places to live. Mexico City, Paris, Tokyo all would become
death traps to the 95% of the population not naturally immune.
Cultures would mutate rapidly, close personal contact between strangers
would become taboo and surgical mask type garb might become a common article
of clothing everywhere. After 7 to 10 years most of the people who were
able to catch your super AIDS would have been exposed and caught it. By the
end of the generation most of them would be dead and only about 300,000,000
people world wide would still be alive and immune, presuming nobody starts
WW III with all out nuclear exchange in that 20 year desperate period.

Always appeal to a man's enlightened self interest, you can trust him to
look out for himself honestly,
It's when you appeal to his Honor or the Common Good that he stops paying
attention.
