Protective Sequestration
Protective sequestration, in public health, is social distancing measures taken to protect a small, defined, and still-healthy population from outsiders during an epidemic (or pandemic) ''before'' the infection reaches that population. It is sometimes referred to as "reverse '' cordon sanitaire''." Due to the disruption that protective sequestration can cause, it is typically considered only under exceptional circumstances where implementation and enforcement are feasible. It is more easily achieved in circumstances where voluntary compliance of the sequestered population is likely. Terminology The term "protective sequestration" was coined by Howard Markel and his colleagues, in their paper that described the successes and failures of several communities in the United States in their attempts to shield themselves from the 1918–1920 Spanish flu pandemic during the second wave of that pandemic (September–December 1918). The term avoids the use of the word quarantine, which, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quarantine
A quarantine is a restriction on the movement of people, animals, and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive quarantines applied throughout the world during the COVID-19 pande ...

The Havasupai people (Havasupai: ''Havsuw' Baaja'') are a Native American people and tribe who have lived in the Grand Canyon for at least the past 800 years. Their name means "people of the blue-green water", referring to Havasu Creek, a tributary of the Colorado. Located primarily in an area known as Havasu Canyon, this Yuman-speaking population once laid claim to an area the size of Delaware (). In 1882, however, the United States federal government forced the tribe to abandon all but of its land. A silver rush and the Atchison, Topeka and Santa Fe Railway in effect destroyed the fertile land. Furthermore, the inception of the Grand Canyon as a national park in 1919 pushed the Havasupai to the brink, as their land was consistently being used by the National Park Service. Throughout the 20th century, the tribe used the US judicial system to fight for the restoration of the land.
