Cordon sanitaire (French pronunciation: ​[kɔʁdɔ̃ sanitɛʁ]) is a French phrase that, literally translated, means "sanitary cordon". It originally denoted a barrier implemented to stop the spread of infectious diseases. It may be used interchangeably with the term "quarantine", and although the terms are related, cordon sanitaire refers to the restriction of movement of people within a defined geographic area, such as a community.[1] The term is also often used metaphorically, in English, to refer to attempts to prevent the spread of an ideology deemed unwanted or dangerous,[2] such as the containment policy adopted by George F. Kennan against the Soviet Union.

For disease

A cordon sanitaire is generally created around an area experiencing an epidemic or an outbreak of infectious disease, or along the border between two nations. Once the cordon is established, people from the affected area are no longer allowed to leave or enter it. In the most extreme form, the cordon is not lifted until the infection is extinguished.[3] Traditionally, the line around a cordon sanitaire was quite physical; a fence or wall was built, armed troops patrolled, and inside, inhabitants were left to battle the affliction without help. In some cases, a "reverse cordon sanitaire" (also known as protective sequestration) may be imposed on healthy communities that are attempting to keep an infection from being introduced. Public health specialists have included cordon sanitaire along with quarantine and medical isolation as "nonpharmaceutical interventions" designed to prevent the transmission of microbial pathogens through social distancing.[4]

The cordon sanitaire is rarely used now because of our improved understanding of disease transmission, treatment and prevention. It remains a useful intervention under conditions in which: 1) the infection is highly virulent (contagious and likely to cause illness); 2) the case fatality rate is very high; 3) treatment is nonexistent or difficult; and 4) there is no vaccine or other means of immunizing large numbers of people.[5]

Historical examples

  • In May 1666, the English village of Eyam famously imposed a cordon sanitaire on itself after an outbreak of the bubonic plague in the community. During the next 14 months almost eighty percent of the inhabitants died.[6] A perimeter of stones was laid out surrounding the village and no one passed the boundary in either direction until November, when the pestilence had run its course. Neighboring communities provided food for Eyam, leaving supplies in designated locations along the boundary cordon and receiving payment in coins “disinfected” by running water or vinegar.[7]
  • During the Great Northern War plague outbreak of 1708-1712, cordons sanitaires were established around affected towns like Stralsund and Königsberg; one was also established around the whole Duchy of Prussia and another one between Scania and the Danish isles along the Sound, with Saltholm as the central quarantine station.[8]
  • In 1770 the Empress Maria Theresa set up a cordon sanitaire between Austria and the Ottoman Empire to prevent people and goods infected with plague from crossing the border. Cotton and wool were held in storehouses for weeks, with peasants paid to sleep on the bales and monitored to see if they showed signs of disease. Travelers were quarantined for 21 days under ordinary circumstances and up to 48 days when there was confirmation of plague being active in Ottoman territory. The cordon was maintained until 1871, and there were no major outbreaks of plague in Austrian territory after the cordon sanitaire was established, whereas the Ottoman Empire continued to suffer frequent epidemics of plague until the mid-nineteenth century.[7]
  • During the 1793 Philadelphia yellow fever epidemic, roads and bridges leading to the city were blocked off by soldiers from the local militia to prevent the illness from spreading. This was before the transmission mechanics of yellow fever were well understood.[9][10]
  • The first actual use of the term cordon sanitaire was in 1821, when the Duke de Richelieu deployed 30,000 French troops to the border between France and Spain in the Pyrenees Mountains, in order to prevent yellow fever from spreading from Spain into France.[11]
  • The 1821 yellow fever epidemic ravaged Barcelona and a cordon sanitaire was set up around the entire city of 150,000 people. Between 18,000 and 20,000 died in four months.[7]
  • During the 1830 cholera outbreak in Russia, Moscow was surrounded by a military cordon, most roads leading to the city were dug up to hinder travel, and all but four entrances to the city were sealed.[7]
  • During the 1856 yellow fever epidemic a cordon sanitaire was implemented in several cities in the state of Georgia with moderate success.[12]
  • In 1869, Adrien Proust (father of novelist Marcel Proust) proposed the use of an international cordon sanitaire to control the spread of cholera, which had emerged from India and was threatening Europe and Africa. Proust proposed that all ships bound for Europe from India and Southeast Asia be quarantined at Suez, however his ideas were not generally embraced.[13][14]
  • In 1882, in response to a virulent outbreak of yellow fever in Brownsville, Texas and in northern Mexico, a cordon sanitaire was established 180 miles north of the city, terminating at the Rio Grande to the west and the Gulf of Mexico to the east. People traveling north had to remain quarantined at the cordon for 10 days before they were certified disease-free and could proceed.[7]
  • In 1888, during a yellow fever epidemic, the city of Jacksonville, Florida was surrounded by an armed cordon sanitaire by order of Governor Edward A. Perry.[15]
  • In 1899 an outbreak of the plague in Honolulu was managed by a cordon sanitaire around the Chinatown district. In an attempt to control the infection, a barbed wire perimeter was created and people's belongings and homes were burned.[16]
  • During the San Francisco plague of 1900–1904 San Francisco's Chinatown was subjected to a cordon sanitaire.[17]
  • In 1902, Louisiana imposed a cordon sanitaire to prevent Italian immigrants from disembarking at the port of New Orleans. The shipping company sued for damages, but the state's right to impose a cordon was upheld in Compagnie Francaise de Navigation a Vapeur v. Louisiana Board of Health.
  • From 1903 to 1914, the Belgian colonial government imposed a cordon sanitaire on Uele Province in the Belgian Congo to control outbreaks of trypanosomiasis (sleeping sickness).[18]
  • The 1918 flu pandemic spread so rapidly that, in general, there was no time to implement cordons sanitaires. However, to prevent an introduction of the infection, residents of Gunnison, Colorado isolated themselves from the surrounding area for two months at the end of 1918. All highways were barricaded near the county lines. Train conductors warned all passengers that if they stepped outside of the train in Gunnison, they would be arrested and quarantined for five days. As a result of this protective sequestration, no one died of influenza in Gunnison during the epidemic.[19]
  • In late 1918, Spain attempted unsuccessfully to prevent the spread of the Spanish flu by imposing border controls, roadblocks, restricted rail travel, and a maritime cordon sanitaire prohibiting ships with sick passengers from landing, but by then the epidemic was already in progress.[20]
  • During the 1972 Yugoslav smallpox outbreak, over 10,000 people were sequestered in cordons sanitaires of villages and neighborhoods using roadblocks, and there was a general prohibition of public meetings, a closure of all borders and a prohibition of all non-essential travel.
  • In 1995 a cordon sanitaire was used to control an outbreak of Ebola virus disease in Kikwit, Zaire.[21][22][5] President Mobutu Sese Seko surrounded the town with troops and suspended all flights into the community. Inside Kikwit, the World Health Organization and Zaire medical teams erected further cordons sanitaires, isolating burial and treatment zones from the general population.[23]
  • During the 2003 SARS outbreak in Canada, "community quarantine" was used to successfully reduce transmission of the disease.[24]
  • During the 2003 SARS outbreak in mainland China, Hong Kong, Taiwan, and Singapore, large-scale quarantine was imposed on travelers arriving from other SARS areas, work and school contacts of suspected cases, and, in a few instances, entire apartment complexes where high attack rates of SARS were occurring.[25] In China, entire villages in rural areas were quarantined and no travel was allowed in or out of the villages. One village in Hebei Province was quarantined from April 12, 2003 until May 13. Tens of thousands of individuals fled from areas when they learned of an impending cordon sanitaire, thereby possibly spreading the epidemic.[26]
  • In August 2014 a cordon sanitaire was established around some of the most affected areas of the 2014 West Africa Ebola virus outbreak.[27][28] On 19 August, the Liberian government quarantined the entirety of West Point, Monrovia and issued a curfew statewide.[29][30] The cordon sanitaire of the West Point area was lifted on 30 August. The Information Minister, Lewis Brown, said that this step was taken to ease efforts to screen, test, and treat residents.[31]

In popular culture

In diplomacy

The seminal use of "cordon sanitaire" as a metaphor for ideological containment referred to "the system of alliances instituted by France in post-World War I Europe that stretched from Finland to the Balkans" and which "completely ringed Germany and sealed off Russia from Western Europe, thereby isolating the two politically 'diseased' nations of Europe."[32]

French Prime Minister Georges Clemenceau is credited with coining the usage, when in March 1919 he urged the newly independent border states (also called limitrophe states) that had seceded from the Russian Empire and its successor the Union of Soviet Socialist Republics to form a defensive union and thus quarantine the spread of communism to Western Europe; he called such an alliance a cordon sanitaire. This is still probably the most famous use of the phrase, though it is sometimes used more generally to describe a set of buffer states that form a barrier against a larger, ideologically hostile state.

In politics

Beginning in the late 1980s, the term was introduced into the discourse on parliamentary politics by Belgian commentators. At that time, the far-right Flemish nationalist Vlaams Blok party began to make significant electoral gains. Because the Vlaams Blok was considered a racist group by many, the other Belgian political parties committed to exclude the party from any coalition government, even if that forced the formation of grand coalition governments between ideological rivals. Commentators dubbed this agreement Belgium's cordon sanitaire. In 2004, its successor party, Vlaams Belang changed its party platform to allow it to comply with the law. While no formal new agreement has been signed against it, it nevertheless remains uncertain whether any mainstream Belgian party will enter into coalition talks with Vlaams Belang in the near future. Several members of various Flemish parties have questioned the viability of the cordon sanitaire. Critics of the cordon sanitaire claim that it is also undemocratic.

With the electoral success of nationalist and extremist parties on the left and right in recent European history, the term has been transferred to agreements similar to the one struck in Belgium:
