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] |
Public Health
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The ''public'' can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of ''health'' takes into account physical, psychological, and social well-being.What is the WHO definition of health? from the Preamble to the Constitution of WHO as adopted by the International Health Conference, New York, 19 June - 22 July 1946; signed on ...

Occupation Of German Samoa
The Occupation of Samoa was the takeover – and subsequent administration – of the Pacific colony of German Samoa by New Zealand during World War I. It started in late August 1914 with landings by the Samoa Expeditionary Force from New Zealand.

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. Quarantine considerations are often one aspect of border control. 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 ...

"The strategy of control and maximum suppression (zero-COVID) has been implemented successfully in a number of countries. The objective of this strategy is to keep transmission of the virus as close to zero as possible and ultimately to eliminate it entirely from particular geographical areas. The strategy aims to increase the capacity to identify and trace chains of transmission and to identify and manage outbreaks, while also integrating economic, psychological, social and healthcare support to guarantee the isolation of cases and contacts.

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 are variable but often include fever, cough, headache, fatigue, breathing difficulties, loss of smell, and loss of taste. Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction).

Havasupai
The Havasupai people (Havasupai: ''Havsuw' Baaja'') are an American Indian tribe who have lived in the Grand Canyon for at least the past 800 years. ''Havasu'' means "blue-green water" and ''pai'' "people". 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 tribe was forced by the federal government to abandon all but of its land. A silver rush and the Santa Fe Railroad 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. In 1975, the tribe succeeded in regaining approximately of their ancestral land with the passage of the Grand Canyon National Park Enlargement Act. As a means of survival, the t ...
