Quarantine

Quarantine (pronounced kwawr-uhn-teen or kwor-uhn-teen)

(1) In historic English common law, the period of 40 days during which a widow was entitled to remain in her deceased husband's home while any dower is collected and returned.

(2) A strict isolation imposed to prevent the spread of disease and (by extension), any rigorous measure of isolation, regardless of the reason.

(3) A period, originally 40 days (the historic understanding of the maximum known incubation period of disease) of detention or isolation imposed upon ships, persons, animals, or plants on arrival at a port or place, when suspected of carrying some infectious or contagious disease; a record system kept by port health authorities in order to monitor and prevent the spread of contagious diseases.  The origin was in measures taken in 1448 in Venice's lazaret to avoid renewed outbreaks of the bubonic plague.

(4) In historic French law, a 40-day period imposed by the king upon warring nobles during which they were forbidden from exacting revenge or to continue warfare.

(5) A place where such isolation is enforced (a lazaret).

(6) In international relations, a blockade of trade, suspension of diplomatic relations, or other action whereby one country seeks to isolate another.

(7) In computing, a place where files suspected of harboring a computer virus or other harmful code are stored in a way preventing infection of other files or machines; the process of such an isolation.

(8) To withhold a portion of a welfare payment from a person or group of people (Australia).

(9) To quarantine someone or something.

1600–1610: From the Middle English quarentine (period a ship suspected of carrying contagious disease is kept in isolation), from the Norman quarenteine, from the French quarenteine, from the Italian quarantina, a variant of quarantena, originally from the upper Italian (Venetian) dialect as quaranta giorni (space of forty days, group of forty), from quaranta (forty) from the Medieval Latin quarentīna (period of forty days; Lent), from the Classical Latin quadrāgintā (four tens, forty) and related to quattuor (four), from the primitive Indo-European root kwetwer (four).  The difference between quarantine and isolation is one of context; while people might for many reasons be isolated, quarantine is a public health measure to deal with those exposed to or at risk of having been infected by a communicable disease, the duration of the quarantine being sufficient to ensure any risk of spreading the infection has passed.  The name is from the Venetian policy (first enforced as the 30 day edict trentino in 1377) of keeping ships from plague-stricken countries waiting off its port for forty days to ensure no latent cases remained aboard.  The extended sense of "any period of forced isolation" dates from the 1670s.  A doublet of carene and quadragene.

In the context the L'Ancien Régime (pre-revolutionary France), it was a calque of the French quarantaine, following the edicts of Louis IX (and formalized by the quarantaine du Roi (1704) of Louis XIV which was a mechanism of quieting squabbling nobles).  Quarantine was introduced to international relations as a euphemism for "blockade" in 1937 because the Roosevelt administration was (1) conscious of public reaction to the effects on civilians of the Royal Navy’s blockade of Imperial Germany during World War I (1914-1918) and (2) legal advice that a “blockade” of a non-belligerent was, under international law, probably an act of war.  The use was revived by the Kennedy administration during the Cuban Missile Crisis (October 1962).  The verb meaning "put under quarantine" came quickly to be used in any sense including figuratively (to isolate, as by authority) dates from 1804.  Predating the use in public health, in early sixteenth century English common law, the quarentine was the period of 40 days during which a widow was entitled to remain in her dead husband's home while any dower is collected and returned.  The alternative spellings quarentine, quarantin, quaranteen, quarantain, quarantaine, quarrentine, quarantene, quarentene, quarentyne, querentyne are all obsolete except in historic references).  While not of necessity entirely synonymous, detention, sequester, separation, seclusion, segregation, sequestration, lazaretto, segregate, confine, separate, seclude, insulate, restrict, detach & cordon, are at least vaguely similar.  Quarantine is a noun & verb, quarantiner is a noun, quarantinable is an adjective and quarantined & quarantining are verbs & adjectives.

In scripture, the number 40 often occurs although Biblical scholars, always anxious to dismiss musings from numerologists, new age practitioners and crystal-wearing basket weavers, reject the notion it has any special meaning beyond the idea of a “period of trial or struggle”, memorably expressed in the phrase “forty days and forty nights”.  In the Old Testament, when God destroyed the earth in the Great Flood, he delivered rain for 40 days and 40 nights (Genesis 7:12).  After killing the Egyptian, Moses fled to Midian where he spent 40 years in the desert tending flocks (Acts 7:30) and subsequently he stood on Mount Sinai for 40 days and 40 nights (Exodus 24:18) and then interceded on Israel’s behalf for 40 days and 40 nights (Deuteronomy 9:18, 25).  In Deuteronomy 25:3, the maximum number of lashes a man could receive as punishment for a crime was set at 40.  The Israelite spies took 40 days to spy out Canaan (Numbers 13:25), the Israelites wandered for 40 years (Deuteronomy 8:2-5) and before Samson’s deliverance, Israel served the Philistines for 40 years (Judges 13:1).  Goliath taunted Saul’s army for 40 days before David arrived to slay him (1 Samuel 17:16) and when Elijah fled from Jezebel, he traveled 40 days and 40 nights to Mt. Horeb (1 Kings 19:8).  The number 40 also appears in the prophecies of Ezekiel (4:6; 29:11-13) and Jonah (3:4).  In the New Testament, the quarentyne was the desert in which Christ fasted and was tempted for for 40 days and 40 nights (Matthew 4:2) and there were 40 days between Jesus’ resurrection and ascension (Acts 1:3).  Presumably, this influenced Western medicine because it was long (and still by some) recommended that women should for 40 days rest after childbirth.

Plague, the Venetians and Quarantino

The Plague of Justinian arrived in Byzantine capital of Constantinople in 541, brought from recently conquered Egypt across the Mediterranean by plague-ridden fleas in the fur of rats on ships bringing loot from the war.  From the imperial capital it spread across Europe, Asia, North Africa and Arabia, killing an estimated thirty to fifty million, perhaps a quarter the inhabitants of the eastern Mediterranean.  Plague never really went away, localized outbreaks happening periodically unit it returned as a pandemic some eight-hundred years later; the Black Death, which hit Europe in 1347, claimed some two-hundred million in just four years and demographically, Europe would not for centuries recover from the Black Death.

There was at the time little scientific understanding of contagion but it became clear it was related to proximity so officials in Venetian-controlled port city of Ragusa (now Dubrovnik in Croatia) resolved to keep newly arrived sailors in isolation until it was apparent they were healthy.  Initially, the sailors were confined to their ships for thirty days, formalized in a 1377 Venetian law as a trentino (thirty days), which radically reduced the transmission rate and by 1448, the Venetians had increased the forced isolation to forty days (quarantine), which, given bubonic plague’s thirty-seven day cycle from infection to death, was an example of a practical scientific experiment.  The word soon entered Middle English as quarantine (already in use in common law as a measure of certain rights accruing to a widow), the origin of the modern word and practice of quarantine.  The English had many opportunities to practice quarentine.  In the three-hundred odd years between 1348 and 1665, London suffered some forty outbreaks, about once a generation (or every twenty years), the significance of this pattern something which modern epidemiologists would later understand.  Quarentine laws were introduced in the early sixteenth century and proved effective, reducing the historic medieval death-rates to about twenty percent.

Eggs à la Lohan

In self-imposed quarantine in March 2020, Lindsay Lohan was apparently inspired by a widely shared motivational poem by Kitty O’Meara (on the internet dubbed the "poet laureate of the pandemic") which included the fragment:

And the people stayed home.  And read books, and listened, and rested, and exercised, and made art, and played games, and learned new ways of being, and were still.  And listened more deeply.  Some meditated, some prayed, some danced.  Some met their shadows.  And the people began to think differently.

One of Lindsay Lohan's recommendations for a time of quarantine was to take the time to cook, posting a photograph of Eggs à la Lohan, a tasty looking omelet.  The poem also contained the words:

And the people healed.  And, in the absence of people living in ignorant, dangerous, mindless, and heartless ways, the earth began to heal.  And when the danger passed, and the people joined together again, they grieved their losses, and made new choices, and dreamed new images, and created new ways to live and heal the earth fully, as they had been healed.

Unfortunately, viewed from early 2023, it would seem Ms O'Meara's hopes quarantine might have left us kinder, gentler and more thoughtful may not have be realized.  It may be Mr Putin didn’t read poem and just ate omelet.
