The 1994 plague in India was an outbreak of bubonic and pneumonic plague in south-central and western India from 26 August to 18 October 1994. [1] 693 suspected cases and 56 deaths were reported from the five affected Indian states as well as the Union Territory of Delhi. These cases were from Maharashtra (488 cases), Gujarat (77 cases), Karnataka (46 cases), Uttar Pradesh (10 cases), Madhya Pradesh (4 cases) and New Delhi (68 cases). There are no reports of cases being exported to other countries. [1]
A committee under chairmanship of Professor Vulimiri Ramalingaswami was formed by the Government of India to investigate the plague episode. In 1995, the committee submitted the report "The Plague Epidemic of 1994" to the government of India. The report concluded that the disease was plague, [2] [3] but did not identify the origin. [4]
Other sources identify the ultimate cause as the 1993 Latur earthquake, [5] which caused a large number of homes to be abandoned with food grains inside. This destabilised the population of domestic and wild rats (in which the plague is endemic), allowing transmission of the plague from wild rats to domestic rats to people. [6] The World Health Organization collected reports of excessive rat deaths in Malma in the Beed district of Maharashtra on 5 August 1994, followed by complaints of fleas. After three weeks, WHO received reports of suspected bubonic plague in Malma, followed by other villages and districts. [7]
Flooding in Surat, which had open sewers, put the bodies of many dead rats on the street, which residents probably came into contact with. [8] The Ganesh Chaturthi festival created crowds in the city shortly thereafter, promoting the spread of pneumonic plague, which was declared on 21 September. [7] By the end of the outbreak, an estimated 78% of confirmed cases were in the slums of Surat. [9]
In the first week of August 1994, health officials reported unusually large numbers of deaths of domestic rats in Surat city of Gujarat state. On 21 September 1994, the Deputy Municipal Commissioner of Health (DMCH) for Surat city received a report that a patient had died seemingly due to pneumonic plague. The DMCH of Surat alerted medical officers in the area where the patient had died. Later that day, a worried caller informed DMCH about 10 deaths in Ved Road residential area and around 50 seriously ill patients admitted to the hospital.
News of the plague spread through Surat city through the night of 21 September 1994. Ill-prepared, medical shops quickly exhausted stocks of tetracycline. [10] This led to panic with people fleeing hospitals fearing infection from other sick patients. [10]
This triggered one of the biggest post-partition migration of people in India with around 300,000 people leaving Surat city in 2 days, [11] [12] for fear of illness or of being quarantined.
Initial questions about whether it was an epidemic of plague arose because the Indian health authorities were unable to culture Yersinia pestis , but this could have been due to lack of sophisticated laboratory equipment. [4] Yet there are several lines of evidence strongly suggesting that it was a plague epidemic: blood tests for Yersinia were positive, a number of individuals showed antibodies against Yersinia and the clinical symptoms displayed by the affected were all consistent with the disease being plague. [12]
About 6,000 cases of fever were misidentified as plague, adding to panic and confusion. [12] Villagers in Rajasthan reportedly tried to exterminate rats, which might have led to more cases as fleas would have had to abandon rat hosts for humans. [12]
Tourism was negatively affected, flights to India were cancelled, and some planes from India were fumigated at airports. [13] Many flights from India to the nearby Gulf region were suspended. Some countries also put a hold on the imports from India. Paramilitary forces set up checkpoints to deal with people fleeing Surat. Panic buying and government-ordered closures spread to Mumbai and Delhi. [12]
Economic damage in Surat was estimated at ₹816 crore (₹8.160 billion). [5] The city implemented massive infrastructure improvements, tearing down slums, covering sewers, constructing public pay toilets, and implementing fines for littering. It also improved its plans for emergency travel advisories, and fired some corrupt officials and disciplined ineffective city workers, including street sweepers. [5]
The Black Death was a bubonic plague pandemic occurring in Europe from 1346 to 1353. It was one of the most fatal pandemics in human history; as many as 50 million people perished, perhaps 50% of Europe's 14th century population. The disease is caused by the bacterium Yersinia pestis and spread by fleas and through the air. One of the most significant events in European history, the Black Death had far-reaching population, economic, and cultural impacts. It was the beginning of the second plague pandemic. The plague created religious, social and economic upheavals, with profound effects on the course of European history.
Plague is an infectious disease caused by the bacterium Yersinia pestis. Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. There are three forms of plague, each affecting a different part of the body and causing associated symptoms. Pneumonic plague infects the lungs, causing shortness of breath, coughing and chest pain; bubonic plague affects the lymph nodes, making them swell; and septicemic plague infects the blood and can cause tissues to turn black and die.
Yersinia pestis is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved and responsible for the Far East scarlet-like fever. It is a facultative anaerobic organism that can infect humans via the Oriental rat flea. It causes the disease plague, which caused the Plague of Justinian and the Black Death, the deadliest pandemic in recorded history. Plague takes three main forms: pneumonic, septicemic, and bubonic. Yersinia pestis is a parasite of its host, the rat flea, which is also a parasite of rats, hence Y. pestis is a hyperparasite.
Pneumonic plague is a severe lung infection caused by the bacterium Yersinia pestis. Symptoms include fever, headache, shortness of breath, chest pain, and coughing. They typically start about three to seven days after exposure. It is one of three forms of plague, the other two being septicemic plague and bubonic plague.
Septicemic plague is one of the three forms of plague, and is caused by Yersinia pestis, a gram-negative species of bacterium. Septicemic plague is a systemic disease involving infection of the blood and is most commonly spread by bites from infected fleas. Septicemic plague can cause disseminated intravascular coagulation and is always fatal when untreated. The other varieties of the plague are bubonic plague and pneumonic plague.
The plague of Justinian or Justinianic plague was an epidemic that afflicted the entire Mediterranean Basin, Europe, and the Near East, severely affecting the Sasanian Empire and the Byzantine Empire, especially Constantinople. The plague is named for the Byzantine Emperor Justinian I, who according to his court historian Procopius contracted the disease and recovered in 542, at the height of the epidemic which killed about a fifth of the population in the imperial capital. The contagion arrived in Roman Egypt in 541, spread around the Mediterranean Sea until 544, and persisted in Northern Europe and the Arabian Peninsula until 549. By 543, the plague had spread to every corner of the empire. As the first episode of the first plague pandemic, it had profound economic, social, and political effects across Europe and the Near East and cultural and religious impact on Eastern Roman society.
The third plague pandemic was a major bubonic plague pandemic that began in Yunnan, China, in 1855. This episode of bubonic plague spread to all inhabited continents, and ultimately led to more than 12 million deaths in India and China, and at least 10 million Indians were killed in British Raj India alone, making it one of the deadliest pandemics in history. According to the World Health Organization, the pandemic was considered active until 1960, when worldwide casualties dropped to 200 per year. Plague deaths have continued at a lower level for every year since.
The Great Plague of Vienna occurred in 1679 in Vienna, Austria, the imperial residence of the Austrian Habsburg rulers. From contemporary descriptions, the disease is believed to have been bubonic plague, which is caused by the bacterium Yersinia pestis, carried by fleas associated with the black rat and other rodents. The city was crippled by the epidemic, which recurred fitfully into the early 1680s, claiming an estimated 76,000 residents.
John Ashburton Thompson was a British-Australian physician and an international authority on plague and leprosy.
Globalization, the flow of information, goods, capital, and people across political and geographic boundaries, allows infectious diseases to rapidly spread around the world, while also allowing the alleviation of factors such as hunger and poverty, which are key determinants of global health. The spread of diseases across wide geographic scales has increased through history. Early diseases that spread from Asia to Europe were bubonic plague, influenza of various types, and similar infectious diseases.
Bubonic plague is one of three types of plague caused by the bacterium Yersinia pestis. One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting, as well as swollen and painful lymph nodes occurring in the area closest to where the bacteria entered the skin. Acral necrosis, the dark discoloration of skin, is another symptom. Occasionally, swollen lymph nodes, known as "buboes", may break open.
Theories of the Black Death are a variety of explanations that have been advanced to explain the nature and transmission of the Black Death (1347–51). A number of epidemiologists from the 1980s to the 2000s challenged the traditional view that the Black Death was caused by plague based on the type and spread of the disease. The confirmation in 2010 and 2011 that Yersinia pestis DNA was associated with a large number of plague sites has led researchers to conclude that "Finally, plague is plague."
The second plague pandemic was a major series of epidemics of plague that started with the Black Death, which reached medieval Europe in 1346 and killed up to half of the population of Eurasia in the next four years. It followed the first plague pandemic that began in the 6th century with the Plague of Justinian, but had ended in the 8th century. Although the plague died out in most places after 1353, it became endemic and recurred regularly. A series of major epidemics occurred in the late 17th century, and the disease recurred in some places until the late 18th century or the early 19th century. After this, a new strain of the bacterium gave rise to the third plague pandemic, which started in Asia around the mid-19th century.
The San Francisco plague of 1900–1904 was an epidemic of bubonic plague centered on San Francisco's Chinatown. It was the first plague epidemic in the continental United States. The epidemic was recognized by medical authorities in March 1900, but its existence was denied for more than two years by California's Governor Henry Gage. His denial was based on business reasons, to protect the reputations of San Francisco and California and to prevent the loss of revenue due to quarantine. The failure to act quickly may have allowed the disease to establish itself among local animal populations. Federal authorities worked to prove that there was a major health problem, and they isolated the affected area; this undermined Gage's credibility, and he lost the governorship in the 1902 elections. The new governor, George Pardee, implemented public-health measures and the epidemic was stopped in 1904. There were 121 cases identified, resulting in 119 deaths.
The 1924 Los Angeles pneumonic plague outbreak was an outbreak of the pneumonic plague in Los Angeles, California that began on September 28, 1924, and was declared fully contained on November 13, 1924. It represented the first time that the plague had emerged in Southern California since plague outbreaks had previously surfaced in San Francisco and Oakland. The suspected reason for this outbreak was a rat epizootic where squirrels that were found to be plague infected were secondarily infected by rats. Due to the evidence of infected squirrels near San Luis Obispo County as late as July 1924 and the migration habits of both squirrels and rats, it is thought that squirrels were the original source of the plague outbreak in Los Angeles.
Madagascar has experienced several outbreaks of bubonic and pneumonic plague in the 21st century. In the outbreak beginning in 2014, 71 died; in 2017, 202 died. Smaller outbreaks occurred in January 2008, and December 2013.
Globally about 600 cases of plague are reported a year. In 2017 and November 2019 the countries with the most cases include the Democratic Republic of the Congo, Madagascar, and Peru.
The Neolithic decline was a rapid collapse in populations between about 3450 and 3000 BCE during the Neolithic period in western Eurasia. The specific causes of that broad population decline are still debated. While heavily populated settlements were regularly created, abandoned, and resettled during the Neolithic, after around 5400 years ago, a great number of those settlements were permanently abandoned. The population decline is associated with worsening agricultural conditions and a decrease in cereal production. Other suggested causes include the emergence of communicable diseases spread from animals living in close quarters with humans.
The 1894 Hong Kong plague, part of the third plague pandemic, was a major outbreak of the bubonic plague in Hong Kong. While the plague was harshest in 1894, it returned annually between 1895 and 1929, and killed over 20,000 in total, with a fatality rate of more than 93%. The plague was a major turning point in the history of colonial Hong Kong, as it forced the colonial government to reexamine its policy towards the Chinese community, and invest in the wellbeing of the Chinese.
The Great Hanoi Rat Massacre occurred in 1902, in Hanoi, Tonkin, French Indochina, when the French government authorities attempted to control the rat population of the city by hunting them down. As they felt that they were making insufficient progress, and due to labour strikes, they created a bounty programme that paid a reward of 1¢ for each rat killed. To collect the bounty, people would need to provide the severed tail of a rat. Colonial officials, however, began noticing rats in Hanoi with no tails. The Vietnamese rat catchers would capture rats, sever their tails, then release them back into the sewers so that they could produce more rats.
