Small pox can occur anywhere. Most of the time, it is found in parts of the world that have not had much contact with it, because, they are not used to the disease and are not immune to it.
It occurred mostly in Europe in medieval times.

the introduction of smallpox
Death from smallpox was iffy, and slow. There were two different strains of smallpox, one causing about 1% fatalities, the other about 30%. The disease caused scarring of the skin and blindness in many of it's victims, and death may occur as a result of secondary infection. In 1979, the World Health Organization announced that smallpox had been eradicated from the planet through a program of vaccination. There have been no cases since then, and it is the only disease that has been eradicated.
No you cannot get Smallpox twice. Like other Pox viruses if you have it once and survive it you have immunity to it from that point on. However, in the current day and age smallpox has been eradicated in the natural world It is ridiculously impossible and improbable that anyone currently has or has had a case of Smallpox since the 1970's when the last cases occurred. There is a vaccine for Smallpox but it is reserved by governments for use in case of a biological terror attack.
Smallpox originated in "the Old World" (Eurasia and Africa) and was brought to "the New World" (the Americas) by Europeans. So, basically, no. US troops didn't "bring smallpox to Europe" because it was already there.
Smallpox is very rare now that sciencetist has figured out a way to cure it. However, back in the 1400s smallpox was common in Mexico where most of the Aztecs suffered from and died. Smallpox was brought by Cortes who spreaded it around in Mexico.
