Etymology and terminology

The word ''quarantine'' comes from ''quarantena'' or ''quarantaine'', meaning "forty days", used in the Venetian language in the 14th and 15th centuries and also in France.

. The medical nature of this isolation is, however, disputed. As traditional exegesis (dated 700 CE) sees it as a punishment for trespassing one of several negative commandment, most notably Evil Speech. A more recent hypothesis postulates that the infected are required to isolate themselves in order to prevent spread of disease (although the Bible does not imply contagiousness of ''Tzaraath''): Moses ordered that dwellings from which infected Jews had gone should be inspected before being occupied again, and that people recovering from contagious disease were not to be allowed to go abroad until examined.

Medieval Europe

The word "quarantine" originates from ''quarantena'', the Venetian language form, meaning "forty days". This is due to the 40-day isolation of ships and people practised as a measure of disease prevention related to the plague. Between 1348 and 1359, the
Black Death The Black Death was a bubonic plague pandemic that occurred in Europe from 1346 to 1353. It was one of the list of epidemics, most fatal pandemics in human history; as many as people perished, perhaps 50% of Europe's 14th century population. ...

prolonged the waiting period to 40 days, thus giving birth to the term "quarantine".The Journal of Sociologic Medicine – Volume 17 The forty-day quarantine proved to be an effective formula for handling outbreaks of the plague. Dubrovnik was the first city in Europe to set up quarantine sites such as the Lazzarettos of Dubrovnik where arriving ship personnel were held for up to 40 days. According to current estimates, the bubonic plague had a 37-day period from infection to death; therefore, the European quarantines would have been highly successful in determining the health of crews from potential trading and supply ships.

Modern history

Epidemics of yellow fever ravaged urban communities in North America throughout the late-eighteenth and early-nineteenth centuries, the best-known examples being the
1793 Philadelphia yellow fever epidemic During the 1793 yellow fever epidemic in Philadelphia, 5,000 or more people were listed in the register of deaths between August 1st and November 9th. The vast majority of them died of yellow fever, making the epidemic in the city of 50,000 peo ...
and outbreaks in Georgia (1856) and Florida (1888). Cholera and smallpox epidemics continued throughout the nineteenth century, and plague epidemics affected Honolulu and San Francisco from 1899 until 1901. State governments generally relied on the '' cordon sanitaire'' as a geographic quarantine measure to control the movement of people into and out of affected communities. During the 1918 influenza pandemic, some communities instituted
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 someti ...

Additionally, the nature of the influenza virus that caused the 1918 pandemic gave rise to a public awareness of the dichotomy between "crowd" and "home" diseases. Simply quarantining the sick in isolation was ineffective in halting the spread of the disease, and new quarantine standards that extended regulations to public spaces became increasingly more common. Most Western countries implemented a range of containment strategies, including isolation, surveillance, and the closure of schools, churches, theatres, and public events.

An additional convention was signed in Paris on 3 December 1903. A multilateral international sanitary convention was concluded at Paris on 17 January 1912. This convention was most comprehensive and was designated to replace all previous conventions on that matter. It was signed by 40 countries, and consisted of 160 articles. Ratifications by 16 of the signatories were exchanged in Paris on 7 October 1920. Another multilateral convention was signed in Paris on 21 June 1926, to replace that of 1912. It was signed by 58 countries worldwide, and consisted of 172 articles. In Latin America, a series of regional sanitary conventions were concluded. Such a convention was concluded in Rio de Janeiro on 12 June 1904.

A bilateral sanitary convention was concluded between the governments of Latvia and Poland on 7 July 1922, for which ratifications were exchanged on 7 April 1925. Another was concluded between the governments of Germany and Poland in Dresden on 18 December 1922, and entered into effect on 15 February 1923. Another one was signed between the governments of Poland and Romania on 20 December 1922. Ratifications were exchanged on 11 July 1923. The Polish government also concluded such a convention with the Soviet government on 7 February 1923, for which ratifications were exchanged on 8 January 1924. A sanitary convention was also concluded between the governments of Poland and Czechoslovakia on 5 September 1925, for which ratifications were exchanged on 22 October 1926.

for this disease was determined and this was to be adopted for administrative purposes. The incubation period was comparatively short, some three or four days. After much discussion ten days was accepted by a majority. The principle of disease notification was unanimously adopted. Each government had to notify other governments of the existence of plague within their jurisdictions and state the measures of prevention being carried out to prevent its spread. The area declared infected was limited to the district or village where the disease prevailed, and no locality was deemed to be infected because of the importation into it of a few cases of plague while there has been no spread. It was decided during the prevalence of plague, every country had the right to close its land borders to traffic. At the

Infected vessels, if these carry a doctor and a disinfecting stove, have a right to navigate the Canal in quarantine and subject only to the landing of those who have plague. In the 20th and 21st centuries, people suspected of carrying infectious diseases have been quarantined, as in the cases of Andrew Speaker (multi-drug-resistant tuberculosis, 2007) and Kaci Hickox (Ebola, 2014).

Signals and flags

Plain yellow, green, and even black flags have been used to symbolise disease in both ships and ports, with the colour yellow having a longer historical precedent, as a colour of marking for houses of infection, previous to its use as a maritime marking colour for disease. The former flag used for the purpose was the "Lima" (L) flag, which is a mixture of yellow and black flags previously used. It is sometimes called the "yellow jack" but this was also a name for yellow fever, which probably derives its common name from the flag, not the colour of the victims (cholera ships also used a yellow flag). The plain yellow flag ("Quebec" or Q in

) probably derives its letter symbol for its initial use in ''quarantine'', but this flag in modern times indicates the opposite—a ship that 'requests free pratique', i.e. that declares itself free of quarantinable disease, and requests boarding and routine port inspection. Ships in quarantine today would fly either the Q flag alone, meaning "My vessel is 'healthy' and I request free pratique", or the double Q flag (QQ), meaning "I require health clearance".

In addition, when quarantine is imposed, public health ethics specify that: * all restrictive actions must be well-supported by data and

(DAWE) is responsible for border inspection of products brought into Australia, and assesses the risks the products might harm Australian environment. No person, goods, and vessels are permitted into Australia without clearance from DAFF. Visitors are required to fill in the information card on arriving in Australia.

Visitors who fail to do so may be subject to a fine of A$444, or may face criminal prosecution and be fined up to A$444,000 or imprisonment of up to 10 years.

, and various arbitrary orders were issued during the next twenty years to meet the supposed danger of infection from the Baltic region. Although no plague cases ever came to England during that period, the restrictions on traffic became more stringent, and in 1788 a very strict Quarantine and Customs Act 1788 ( 28 Geo. 3. c. 34) was passed, with provisions affecting cargoes in particular. The act was revised in 1801 and 1805, and in 1823–24 an elaborate inquiry was followed by an act of Parliament making quarantine only at discretion of the privy council, which recognised yellow fever or other highly infectious diseases as calling for quarantine, along with plague. The threat of cholera in 1831 was the last occasion in England of the use of quarantine restrictions. Cholera affected every country in Europe, despite all efforts to keep it out. When cholera returned to England in 1849, 1853 and 1865–66, no attempt was made to seal the ports. In 1847 the privy council ordered all arrivals with a clean bill of health from the

The whole detention of the vessel was from sixty to sixty-five days, including the time for reshipment of her cargo. Pilots had to pass fifteen days on board a convalescent ship.

They certified in writing the master of a supposedly infected ship, and detained the vessel provisionally for not more than twelve hours, giving notice meanwhile to the port sanitary authority. The medical officer of the port boarded the ship and examined every person in it. Every person found infected was taken to a hospital and quarantined under the orders of the medical officer, and the vessel remained under his orders. Every person suspected could be detained on board for 48 hours or removed to the hospital for a similar period. All others were free to land upon giving the addresses of their destinations to be sent to the respective local authorities, so that the dispersed passengers and crew could be kept individually under observation for a few days. The ship was then disinfected, dead bodies buried at sea, infected clothing, bedding, etc., destroyed or disinfected, and bilge-water and water-ballast pumped out at a suitable distance before the ship entered a dock or basin. Mail was subject to no detention. A stricken ship within 3 miles of the shore had to fly a yellow and black flag at the main mast from sunrise to sunset.


United States

In the United States, authority to quarantine people with infectious diseases is split between the state and federal governments. States (and tribal governments recognised by the federal government) have primary authority to quarantine people within their boundaries. Federal jurisdiction only applies to people moving across state or national borders, or people on federal property.

Hubei

In Hubei, the origin of the epidemic, a '' cordon sanitaire'' was imposed on Wuhan and other major cities in China, affecting around 500 million people, which is unprecedented in scale in human history, to limit the rate of spread of the disease. The 'lockdown' of Wuhan, and subsequently a wider-scale 'lockdown' throughout Hubei province, began on 23 January 2020. At this stage, the spread of the virus in mainland China was running at approximately 50% growth in cases per day. On 8 February, the daily rate of spread fell below 10%.

, effectively quarantining more than 50,000 people. This followed a second day when the declared detected cases leapt enormously (the period from 21 to 23 February saw daily increases of 567%, 295% and 90% respectively). A week later the rate of increase of cases in Italy was significantly reduced (the period from 29 February to 4 March saw daily increases of 27%, 50%, 20%, 23%, and 23%). On 8 March 2020, a much wider region of Northern Italy was placed under quarantine restrictions, involving around 16 million people. On the next day, the quarantine was extended to the whole of Italy, effective on 10 March 2020, placing roughly 60 million people under quarantine. A team of Chinese experts, together with some 31 tonnes of supplies, arrived in Rome on 13 March 2020 to help Italy fight the virus. On 22 March 2020, Russia sent nine Ilyushin 76 planes with expert virologists, epidemiologists, medical equipment, and pharmaceuticals in a humanitarian aid operation that Italian media dubbed "From Russia With Love". Eventually the lockdown was extended until 3 May, although starting from 14 April stationery shops, bookshops, and children clothing's shops were allowed to open. On 26 April 2020, the so-called "Phase 2" was announced, to start from 4 May. Movements across regions were still forbidden, while movements between municipalities were allowed only to visit relatives or for work and health reasons. Moreover, closed factories could re-open, but schools, bars, restaurants, and barbers were still closed. As at 4 May 2020, when new cases were running around 0.5%, ( persons) per day and consistently falling, it was expected that museums and retailers might reopen from 18 May, while hairdressers, bars and restaurants were expected to reopen fully on 1 June. Regional lockdowns were subsequently imposed as further waves of the virus spread through the country.

Rest of the world

In the immediate context of the start of the pandemic in Wuhan, countries neighbouring or close to China adopted a cautious approach.
