Study links uneven urbanisation with high risk of cholera outbreaks

By Sunderarajan Padmanabhan

Families living in rural areas of districts at higher risk of cholera as funds for water and sanitation infrastructure are diverted to urban areas, say experts

New Delhi: Higher levels of urbanisation are no guarantee for preventing the outbreak of cholera. In fact, a new study by Indian and international experts seems to indicate that higher urbanisation also leads to an increased risk of a cholera epidemic since funds for water and sanitation infrastructure are often allocated disproportionately within an ‘urban’ district, with its rural areas receiving only a pittance.

In other words, the study blames the uneven allocation of funds for water and sanitation infrastructure within districts – urban centres getting more funds than rural areas within a district that is otherwise categorised as ‘urban’. The use of improved sanitation facilities in urban areas in India has increased to 63 per cent as of 2015 while it has gone up to only 28 per cent in rural areas.

“It appears that families living in rural areas of districts with more cities are at higher risk, perhaps because the resources in these districts are allocated to the urban areas, neglecting the rural areas of the district,” the researchers have observed in their study in journal PLOS One.

The study has also found that there seemed to be large scale underreporting of cholera cases. There is significant variation between actual number of cases being reported and ground reality based on the various risk factors. For instance, the study says, Uttar Pradesh did not report any case despite having areas that qualified as ‘high risk’ zones. The reasons for underreporting are limited disease surveillance, inadequate laboratory capacity especially at the peripheral health care centres, and reluctance on part of authorities to acknowledge the problem for fear of societal repercussions.

The findings are based on district level data of cases reported between 2010 to 2015 from the Integrated Disease Surveillance Programme, and socioeconomic characteristics and coverage of water and sanitation obtained from the 2011 census report. Researchers used this data to perform spatial analysis to identify cholera hotspots, and employed a modeling method called ‘zero-inflated Poisson regression’ to identify the factors associated with cholera and predicted case counts at district level.

A total of 27,615 cholera cases were reported during the six-year period. As many as 24 out of the 36 states in the country had reported cholera during these years. Of them, 13 States were classified as endemic. In terms of districts, out of the 641 districts in the country, 78 districts in 15 states were identified as “hotspots” based on the reported cases. However, 111 districts in nine states were identified as “hotspots” from model-based predicted number of cases.

Overall, one-fourth of the districts in India reported cholera and 90 districts of them have been identified as hotspots, making cholera is a widespread major public health problem in the country. It is major problem in West Bengal, Karnataka, Chhattisgarh, Punjab, and areas of Himachal Pradesh adjoining Punjab. In addition, most districts in Karnataka have been identified as cholera hotspots. The risk for cholera in a district is linked with poor sanitation and drainage conditions and urbanization level in the district.

The research team included Mohammad Ali and David A.Sack of Department of International Health, Johns Hopkins Bloomberg School of Public Health; Nirmal K. Ganguly, Sanjukta Sen Gupta, and Nisha Arora of Policy Center for Biomedical Research, Translational Health Science and Technology Institute; Pradeep Khasnobis and Srinivas Venkatesh of National Center for Disease Control; Dipika Sur of Indian Public Health Association; and Gopinath B. Nair of World Health Organization.

Union Home Minister Amit Shah on Saturday praised Dharmendra Pradhan’s decision to step down as Union Education Minister, saying the move reflected the Bharatiya Janata Party’s commitment to placing the nation and students above any political position.

In a post on X, Shah said that for BJP workers, the country, its youth and students are more important than any office. He described Pradhan’s resignation as an example of the party’s guiding principle of prioritising national interest over personal ambition.

Shah highlights government’s focus on exam reforms

Amit Shah said the Narendra Modi-led government respects the sentiments of students and remains committed to strengthening the examination system following concerns over alleged paper leaks.

He said the Centre has introduced strict measures to ensure severe punishment for those involved in examination paper leaks and expressed confidence that these steps would deliver justice to students who cleared the National Eligibility-cum-Entrance Test (NEET).

Praises Pradhan’s work as Education Minister

Recalling Dharmendra Pradhan’s tenure, Shah highlighted several initiatives undertaken during his time in the Education Ministry. He credited Pradhan with helping implement the National Education Policy (NEP), expanding PM SHRI schools, promoting digital education, strengthening skill development and improving coordination between industry and academic institutions.

Shah also said Pradhan worked towards making examinations more inclusive and student-centric, adding that his tenure reflected his commitment to the vision of a developed India.

Resignation follows NEET controversy

Dharmendra Pradhan’s resignation comes amid nationwide protests over alleged irregularities in the NEET examination and growing demands for accountability.

The resignation has triggered political reactions across party lines. While opposition parties have described the development as a result of sustained student protests, BJP leaders have projected it as an example of accountability and commitment to national interest.

The Uttar Pradesh government has reconstituted a Special Investigation Team (SIT) headed by IG Kiran S, with DIG Somen Verma and SSP Dr Gaurav Grover as members, to investigate the alleged theft of donations meant for the Ram Temple in Ayodhya. 

The move comes after directions from the Supreme Court, which sought a reconstituted investigation team to ensure an independent and comprehensive probe into the allegations.

The newly formed SIT is expected to continue the investigation and submit a status report before the Supreme Court on July 27.

Senior IPS officers to lead the probe

According to the state government, the investigation will now be supervised by senior IPS officers.  The revamped SIT has been tasked with examining all aspects of the alleged embezzlement of temple donations and carrying the investigation forward.

The Supreme Court had observed that criminal investigations and technical examination of theft-related cases are more effectively handled by experienced police officers, leading to the reconstitution of the SIT under senior IPS leadership.

Probe to continue under court supervision

The case relates to the alleged embezzlement of offerings (chadhava) donated by devotees at the Shri Ram Janmabhoomi Temple in Ayodhya.

The Supreme Court is monitoring the investigation and will review the SIT’s status report at the next hearing.

Authorities are expected to continue examining evidence collected during the earlier stages of the investigation as the newly constituted SIT proceeds with the case.
