Donald "D.A." Henderson, a physician, educator, and epidemiologist who led the World Health Organization's campaign to eradicate smallpox, died at 87 years of age on Aug. 19, 2016.
Smallpox was responsible for an estimated 300–500 million deaths during the 20th century. As recently as 1967, the World Health Organization (WHO) estimated that 15 million people contracted the disease and that two million died in that year.
After vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the global eradication of smallpox in 1979. Smallpox is one of two infectious diseases to have been eradicated, the other being rinderpest, which was declared eradicated in 2011.
Key to the eradication effort, given an insufficient supply of vaccine to inoculate everyone, was "surveillance-containment":
This technique entailed rapid reporting of cases from all health units and prompt vaccination of household members and close contacts of confirmed cases.

For example, the UK during WW2, they had cracked German military codes. As such they knew that the Germans were going to bomb a city. You are left with the choice of evacuating the city or not. If you evacuate the city or otherwise increase aerial defenses, you risk letting the Germans know their codes are cracked, which would gravely undermine the war effort and possibly lead to a German victory. If you do not evacuate the city, hundreds of civilians will die. What do you do?
Move to America.
