Smallpox was an infectious disease caused by variola virus (often called smallpox virus), which belongs to the genus Orthopoxvirus. [7] [11] The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, [10] making smallpox the only human disease to have been eradicated to date.
After the epidemic, the Hudson Bay Company implemented a territory wide vaccination program which further reduced smallpox deaths. Unfortunately, as people entered communities to vaccinate against smallpox, they brought with them other diseases that kept mortality rates high. [2] The epidemic altered power structures of impacted nations.

Prediabetes, often considered the step before diabetes, is when you have higher than usual blood glucose (blood sugar) levels. Your levels aren’t high enough to be classified as type 2 diabetes.
Between 1910 and 1920, techniques for measuring blood sugar (glucose test) were rapidly improved, allowing experiments to be conducted with greater efficiency and precision. [93] These developments also helped establish the notion that high blood sugar levels (hyperglycemia), rather than glycosuria, was the important condition to be relieved.
Thompson showed signs of improved health and went on to live 13 more years taking doses of insulin, before dying of pneumonia at age 26. [ 3 ] [ 4 ] Until insulin was made clinically available, a diagnosis of type 1 diabetes was a death sentence, more or less quickly (usually within months, and frequently within weeks or days).
