Pandemic & Epidemic

Pandemic (pronounced pan-dem-ik)

(1) Of a disease, prevalent throughout an entire country, continent, or the whole world; epidemic over a large area (in modern use, now usually restricted to diseases spread over several continents, reaching epidemic level in at least two.

(2) In figurative use, general; universal.

1660-1670: From the Late Latin pandēmus (affecting all the people, public, general) from the Ancient Greek pandēmos (general) and the Ancient Greek πᾶν (pân) (all; equivalent to English pan-) + δῆμος (dêmos) (the people); the suffix –os was the adjectival form.  The suffix –ic is from the Middle English -ik, from the Old French -ique, from the Latin -icus, from the primitive Indo-European –kos.  The form existed in the Ancient Greek as -ικός (ikós), in the Sanskritas as श (śa) & क (ka) and in the Old Church Slavonic as -ъкъ (-ŭkŭ); a doublet of -y.  The suffix –ic is often added to words of Greek or Latin origin, but may be used regardless of source.  In modern English, there is sometimes the creation of redundant forms such as veganic (from vegan).  Related words include the nouns pandemia & pandemicity and the adjective interpandemic.

Epidemic (pronounced ep-i-dem-ik)

(1) Of a disease and affecting many persons at the same time, and spreading from person to person in a locality where the disease is not permanently prevalent.

(2) Extremely prevalent; widespread; a rapid spread or increase in the occurrence of something.

1595-1605: From the French épidémique, from épidémie, from the Latin epidemia, from the Ancient Greek ἐπιδήμιος (epidḗmios), from ἐπί (epí) (upon) + δῆμος (dêmos) (people) the Ancient Greek epidēmía translates literally as “among the people” but is often cited as “staying in one place”.  The early alternative forms epidemy and epidemick are long obsolete and related forms include the noun epidemicity, the adjectives interepidemic & preepidemic and the adverb epidemically.

Noted Pandemics

HIV/AIDS Pandemic (2005-2012)

Death Toll: 36 million; Cause: HIV/AIDS

First identified in Democratic Republic of the Congo in 1976, HIV/AIDS is a global pandemic with some 35 million people living with HIV, the vast majority in Sub-Saharan Africa, where 5% of the population (circa 21 million) is infected.  The AIDS death toll is thought to be understated because (1) dubious validity of statistical record-keeping in some countries (there are places where many deaths are not accompanied by a death certificate) and (2) a cultural reluctance among families to have AIDS recorded as the cause because of the association with homosexuality and IV drug use, hence the 1980s spike in recorded deaths from pneumonia.     

Flu Pandemic (1968)

Death Toll: 1 million; Cause: Influenza

A category 2 Flu also known as “Hong Kong Flu,” it was caused by the H3N2 strain of the Influenza A virus, an offshoot of H2N2.  It took only days to reach Singapore and Vietnam, and, within three months, had spread to The Philippines, India, Australia, Europe, and the US.  Although wide-spread, it had a low mortality rate under 1%.  Worst affected was Hong Kong where 500,000 died, some 15% of the population.

Asian Flu (1956-1958)

Death Toll: 2 million; Cause: Influenza

A pandemic of Influenza A of the H2N2 subtype, it originated in China, spreading from the province of Guizhou to Singapore, Hong Kong, and the United States.  Estimates for the death toll vary but the World Health Organization (WHO) lists 2 million deaths, 69,800 of them in the US.

Flu pandemic (1918-1919)

Death Toll: 20-50 million; Cause: Influenza

The best known pandemic, it infected over a third of the world’s population, killing between 20–50 million.  The mortality rate was a high 10-20% and unusually, where influenza had previously killed mostly juveniles, the elderly or already weakened patients, the 1918 pandemic disproportionally killed robust and healthy young adults, leaving children and those with weaker immune systems still alive.  The movement of vast numbers of people around the world at the end of WWI assisted the spread.

Sixth Cholera pandemic (1910-1911)

Death Toll: 800,000+; Cause: Cholera

Like its previous five incarnations, the Sixth Cholera Pandemic originated in India where it killed over 800,000, before spreading to the Middle East, North Africa, Eastern Europe and Russia.  It was the source of the last American outbreak of Cholera although effective public health measures there restricted the death toll to eleven.  Cholera, a classic Medieval disease, remains endemic in India.

Flu pandemic (1889-1890)

Death Toll: 1 million; Cause: Influenza

Know at the time as Asiatic or Russian Flu and though once to be a strain of the Influenza A H2N2, it was an outbreak of H3N8.   The first cases were observed in May 1889 in three distant locations, Bukhara in Central Asia (Turkestan), Athabasca in north-western Canada, and Greenland. The rapid growth in urban populations provided vectors for the spread and although the first true pandemic in the era of bacteriology, while much was learned from it, it claimed over a million lives.

Third Cholera pandemic (1852–1860)

Death Toll: 1 million; Cause: Cholera

Probably the most deadly of the seven cholera pandemics, it was the third major outbreak in the 19th century.  Like the first and second, the third originated in India, before spreading with extraordinary rapidity through Asia, Europe, North America and Africa.  A physician in England, where over 20,000 died, discovered contaminated water was the means of transmission.

The Black Death (1346-1353)

Death Toll: 75 – 200 million; Cause: Bubonic Plague

The Plague ravaged Europe, Africa, and Asia, with a death toll of 75-200 million, killing up to half the population of some European countries.  Thought to have originated in Asia, Plague was most likely spread by fleas living on the rats of merchant ships and in some countries, populations didn’t recover until the nineteenth century.  Now unknown in most parts of the world, outbreaks still happen in various places.

Plague of Justianian (541-542)

Death Toll: 25 million; Cause: Bubonic Plague

Thought to have killed perhaps half the population of Europe, the Plague of Justinian afflicted the Byzantine Empire and Mediterranean port cities.  The first verified and well-documented incident of the Bubonic Plague, it reduced the population of the Eastern Mediterranean by a quarter and devastated Constantinople, where, at the height of the pandemic, 5,000 a day were dying.

Antonine Plague (165 AD)

Death Toll: 5 million; Cause: Unknown

Also known as the Plague of Galen, the Antonine Plague affected Asia Minor (modern Turkey), Egypt, Greece, and Italy and is thought to have been either Smallpox or Measles, though the true cause is unknown. The disease was brought to Rome by soldiers returning from Mesopotamia.  The pandemic significantly weakened the Roman army.
