Washington understood the destructive nature of smallpox and other diseases such as malaria, diphtheria, and scarlet fever. He was one of the first to introduce the idea of compulsory health initiatives such as widespread inoculation. Washington also had experience with disease outside the realm of combat and war.
According to David Thompson's account, the first to hear of the disease were fur traders from the Hudson's House on October 15, 1781. [75] A week later, reports were made to William Walker and William Tomison, who were in charge of the Hudson and Cumberland Hudson's Bay Company posts. By February, the disease spread as far as the Basquia Tribe.
Europeans carried such endemic diseases when they migrated and explored the New World. Europeans often spread infectious diseases to Native Americans through trading and settlement efforts, and these could even be transmitted far from the sources and colonial settlements, including through exclusively Native American trading transactions.

This disease is transmitted by the bite of female mosquito; the higher prevalence of transmission by Aedes aegypti has led to it being known as the Yellow Fever Mosquito. The transmission of yellow fever is entirely a matter of available habitat for vector mosquito and prevention such as mosquito netting. They mostly infect other primates, but ...
During the following months it wreaked havoc in Prussia, Switzerland, and northern Europe. [47] The last outbreak was in England in 1556. [48] The disease – which killed tens of thousands of people – was probably influenza [49] or a similar viral infection, [50] but records from the time when medicine was not a science can be unreliable.

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.
Smallpox is the first disease, and so far the only infectious disease of humans, to be eradicated by deliberate intervention. [6] It became the first disease for which there was an effective vaccine in 1798 when Edward Jenner showed the protective effect of inoculation (vaccination) of humans with material from cowpox lesions.
