    Originally from Europe, Asia, and Arabia where it had less of an impact. The Natives in the New World didn't have the natural immunities yet so they had no way to protect themselves from this disease. Killed 90%-95% of the indigenous people in the americas over a century. Centuries later in the late 18th century Edward Jenner invented a vaccine to the virus making it the first epidemic to end by vaccine. Smallpox wasn't completely eradicated until 1980.
