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.

IPS officer Nupur Prasad, who led the CBI investigation into actor Sushant Singh Rajput’s death, has been recognised with the Medal for Meritorious Service (MSM) this year.

A 2007-batch AGMUT cadre officer, Ms Prasad recently returned to the Delhi Police after completing her tenure with the CBI. She is currently serving as Joint Commissioner of Police in the Economic Offences Wing (EOW), where she oversees investigations involving financial and economic crimes.

The award is part of this year’s recognition for police personnel for distinguished and meritorious service. Such honours recognise contributions in areas including investigation, crime prevention, public service, law and order and administration.

Nupur Prasad’s role in Sushant Singh Rajput case

Ms Prasad came into national focus during the CBI investigation into the death of Sushant Singh Rajput, who was found dead at his Mumbai residence on June 14, 2020.

The case was transferred to the CBI in August 2020 following a complaint by the actor’s family and a legal dispute over jurisdiction.

During her tenure with the agency, Ms Prasad supervised key aspects of the investigation, including the examination of witness statements, forensic evidence and medical records.

In 2025, the CBI filed closure reports, saying its investigation found no evidence of foul play, abetment to suicide or criminal conspiracy in the actor’s death.

Career across Delhi Police, CBI

Ms Prasad has served in several positions during her career, including assignments in the Delhi Police, CBI, Arunachal Pradesh and West Bengal.

Before joining the CBI, she held senior positions in the Delhi Police and became the first Deputy Commissioner of Police (DCP) of Shahdara. During her tenure, she worked on establishing the district’s policing framework following its creation.

She also led operations targeting drug networks and illegal gambling activities while focusing on crime-prevention measures.

Later, as DCP of North Delhi, she oversaw security arrangements for major events, including Independence Day celebrations at the Red Fort and Delhi University elections.

Community-focused policing initiatives

Beyond investigations, Ms Prasad has been associated with community-focused programmes involving women’s self-defence, youth development, cyber safety and drug de-addiction.

During her CBI tenure, she was also associated with several prominent investigations. Media reports have linked her to cases concerning businessman Vijay Mallya and the AgustaWestland helicopter deal.

Current role in Delhi Police

After completing her assignment with the CBI, Ms Prasad returned to the Delhi Police and took charge as Joint Commissioner of Police in the Economic Offences Wing.

The latest recognition adds to her career spanning investigations, policing and public service across several challenging assignments.

Rahul Kharge

Congress president Mallikarjun Kharge and Leader of Opposition in the Lok Sabha Rahul Gandhi skipped the 80th Independence Day celebrations at Delhi’s Red Fort for the second consecutive year.

Prime Minister Narendra Modi led the Independence Day celebrations at the historic venue on Saturday.

The absence of the two senior Congress leaders comes amid strained relations between the ruling party and the Opposition, which further deteriorated during the Monsoon Session of Parliament that concluded on Thursday.

2024 seating controversy

Rahul Gandhi had attended the Independence Day celebrations in 2024 but his seating arrangement triggered a controversy. The Congress leader, who holds the status of a Cabinet minister as Leader of the Opposition in the Lok Sabha, was seated in the second-last row during the ceremony at the Red Fort.

The Opposition had criticised the seating arrangement, calling it an insult to the people. The Defence Ministry, which organised the event, said the arrangement had been modified to accommodate Olympians at the venue.

According to protocol, the Leader of the Opposition is seated in the front row during ceremonial events.

Opposition-ruling party tensions

Relations between the government and the Opposition remained tense during the Monsoon Session, which ended on Thursday.

The session saw repeated clashes between the two sides, with both the Opposition and the ruling party blaming each other for the low productivity of Parliament.

The session began on July 20, with students marching towards Parliament on the first day. Twelve bills were passed during the session, while detailed discussion took place on only one legislation, concerning paper leaks.

The Congress, along with the Trinamool Congress and Samajwadi Party, also boycotted the customary tea party hosted by Lok Sabha Speaker Om Birla after the House was adjourned sine die.
