The history of smallpox extends into pre-history. [1] Genetic evidence suggests that the smallpox virus emerged 3,000 to 4,000 years ago. [ 2 ] Prior to that, similar ancestral viruses circulated, but possibly only in other mammals, and possibly with different symptoms.
Smallpox vaccine was available in Europe, the United States, and the Spanish Colonies during the last part of the century. [4] [5] The Latin names of this disease are Variola Vera. The words come from various (spotted) or varus (pimple). In England, this disease was first known as the "pox" or the "red plague".

Most estimates coalesce around a fatality rate of about 10% (7.5 million people) of the total population of the empire with death rates of up to 15% in the cities and the army. If the pandemic was indeed smallpox, the number who died would have probably been about 25% of those infected as the survival rate from smallpox is often around 75%. [30 ...
The first known smallpox epidemic to strike the native peoples of the coastal and interior Pacific Northwest arrived in the early 1770s, devastating large swathes of the population and causing significant demographic collapse – both from the disease itself and corresponding malnutrition from the deaths of hunters within tribes.
