Third plague pandemic
The third plague pandemic was a major plague pandemic that began in Yunnan, China, in 1855. Its name refers to its status as the third of at least three known major pandemics caused by the spread of the bacterium Yersinia pestis. This episode of bubonic plague spread to all inhabited continents, and ultimately led to at least 15 million deaths worldwide, including 10-12 million in British Raj India and 2.2 million in China. Though it is estimated to have killed fewer people than the second plague pandemic (and possibly the first), the third plague pandemic had one of the highest death tolls among pandemics in human history.
According to the World Health Organization, the pandemic was considered active until 1960, when worldwide casualties dropped below 200 per year. Plague deaths have continued at a lower level ever since, as plague persists in enzootic reservoirs across Asia, Africa, South America, and the western United States.
The first plague pandemic began with the Plague of Justinian, which ravaged the Byzantine Empire and surrounding areas in 541 and 542; the pandemic persisted in successive waves until the middle of the 8th century. The second began with the Black Death, which killed at least one third of Europe's population in a series of expanding waves of infection from 1346 to 1353; this pandemic recurred regularly until the 19th century.
The plague which spread from Yunnan along China's Southeast Coast and across the world manifested almost exclusively as bubonic plague, with documentation of incidental pneumonic and septicemic forms. It was carried around the world through ocean-going trade, through transporting infected persons, rats, and cargoes harboring fleas.
Historians of the late-Qing plague epidemics generally include the Manchurian plague epidemic of 1910-11, which killed between 45,000-60,000 people, as defined within the third pandemic's scope. The pneumonic Manchurian plague epidemic was geographically, ecologically, genetically, and epidemiologically distinct from the bubonic plague which spread globally from Southern China. It spread throughout the region of Manchuria, reaching Vladivostok and Beijing (which was connected to Manchuria by the Imperial Chinese Railway), but not far beyond due to port and railway closures as well as preventive medical protocols.
The bubonic plague was endemic in populations of infected ground rodents in Central Asia and was a known cause of death among the migrant and established human populations in that region for centuries. An influx of new people because of political conflicts and global trade led to the spread of the disease throughout the world from Asia to the rest of Europe, to reach Africa and the Americas.[citation needed]
A natural reservoir or nidus for plague is in western Yunnan: it is still a health risk. The third pandemic of plague originated in the area after a rapid influx of Han Chinese to exploit the demand for minerals, primarily copper, in the second half of the 19th century. By 1850, the population had exploded to over 7 million people. Increasing transportation throughout the region brought people in contact with plague-infected fleas, the primary vector between the yellow-breasted or buff-breasted rat (Rattus flavipectus) aka Rattus tanezumi and humans. People brought the fleas and rats back into growing urban areas, where small outbreaks sometimes reached epidemic proportions. The plague spread further and began to appear in the Pearl River delta, including Canton and Hong Kong. Although William McNeil and others believe the plague to have been brought from the interior to the coastal regions by troops returning from battles against the Muslim rebels, Benedict suggested evidence to favour the growing and lucrative opium trade, which began after about 1840.
In the city of Canton, beginning in March 1894, the disease killed 80,000 people in a few weeks. Daily water-traffic with the nearby city of Hong Kong rapidly spread the plague. Within two months, after 100,000 deaths, the death rates dropped below epidemic rates, but the disease continued to be endemic in Hong Kong until 1929. The plague reached many cities such as Yunnan, Hong Kong, Mecca, Medina, Kobe, Calcutta, etc.
