Short description: Outbreak of bubonic and pneumonic plague


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]

Cause

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]

Spread of the disease

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.

Confusion over disease identification

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]

Economic impact and hygiene improvements

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]
