What is quarantine in public health?

[ad_1]

Quarantine is a public health measure that is intended to prevent the spread of infectious diseases. When someone or something is quarantined, they are isolated in a safe area so that other people cannot come into direct contact. Once the threat has been eliminated, the person or object is released back into general society. Quarantine has a very long history and also serious ethical and legal implications, as people can be forced into quarantine against their will.

The term comes from the Italian forty gods. It derives from the tradition of ordering ships to stay offshore for forty days when arriving from regions with active cases of plague. The idea behind these first quarantines was to establish that no one on board carried the plague. Unfortunately, as the disease is transmitted by fleas and rats, these early quarantines may not have been very effective. However, the idea of ​​isolating people who had been exposed to dangerous diseases persisted.

The 40-day deadline, however, is no longer valid. A quarantine can be very short, as in the case of someone being asked to undergo decontamination after being exposed to something dangerous, or extremely long. Patients in extended quarantine are usually provided with reasonably comfortable surroundings and personal services to make the quarantine more enjoyable. After the quarantine ends, most of the things the patient was in contact with are destroyed, as they may be contaminated.

When a disease is endemic in a society, quarantine is not used, because it would be impossible to confine all infected parts. However, when an autonomous patient is diagnosed with a highly infectious or dangerous disease, he or she may be quarantined to avoid exposing the general population. Also, the person in quarantine is usually asked to make a list of people they have had contact with, so they can be quarantined as well. Once the disease has run its course or it has become clear that someone is not infected, the quarantined individual is released.

Individual quarantines limit personal freedoms, but benefit society as a whole. Quarantine laws are very rarely enforced in the modern era, in part due to the immense legal and ethical complications that can accompany quarantines. In fact, some public health institutions actually lack the legal authority to force someone into quarantine, although they may require someone to voluntarily submit to it. During the quarantine, the patient will also be provided with high-quality medical care, both to fight the disease and to encourage the patient to stay.

While some people may question whether or not quarantine is necessary, many medical professionals agree that it is indeed necessary, especially in the case of virulent disease or drug-resistant infections. This is especially true with a disease that has no known cure, as the escape of the disease in the general population could be catastrophic. A short list of infections deserve quarantine, and the diseases on the list include things like Ebola, smallpox, and other highly virulent infectious diseases.
