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.

Lok Sabha clears bill to levy cess on pan masala and similar goods for health, security funding

The Lok Sabha has passed a bill to impose a cess on pan masala manufacturing units, aiming to create a dedicated revenue source for public health and national security initiatives.

Nirmala Sitharaman

The Lok Sabha has approved the Health Security se National Security Cess Bill, 2025, paving the way for a new cess on pan masala manufacturing units. The legislation aims to generate dedicated funds for strengthening national security and improving public health, both areas identified as critical national priorities.

Bill aims to create predictable funding stream

Finance Minister Nirmala Sitharaman, responding to the debate before the bill was passed by voice vote, said that the cess will be shared with states because public health falls under the state list.

The new cess will be applied over and above the GST, based on production capacity and machinery used in units manufacturing pan masala and similar goods. The minister clarified that this cess will not affect GST revenue, and that pan masala already attracts the maximum GST slab of 40 per cent.

According to the bill text, the objective is to build a “dedicated and predictable resource stream” to support expenditure related to health and national security.

Sitharaman also mentioned that cess collection as a percentage of gross total revenue currently stands at 6.1 per cent, lower than the 7 per cent average between 2010 and 2014.

Simone Tata passes away at 95: A look at the visionary who shaped Lakme and modern retail

Simone Tata, the pioneering business leader who built Lakme and helped shape India’s modern retail sector, passed away at 95. Here’s a look at her legacy.

Ratan Tata’s stepmother and celebrated business leader Simone Tata passed away on December 5, 2025, at the age of 95. Known for her pioneering role in building Lakme and transforming India’s retail landscape, she leaves behind a remarkable legacy that redefined Indian consumer culture.

A legacy that shaped Indian business

Simone Tata, born in Geneva in 1930, first came to India at the age of 23. Two years later, in 1955, she married Naval H. Tata and gradually became an integral part of the Tata family’s business vision. Her journey with the Tata Group began in the 1960s, when she was appointed to Lakme—then under Tata Oil Mills.

Under her leadership, Lakme quickly grew into one of India’s most trusted cosmetic brands. She rose to the position of managing director and later chairperson, introducing global formulations and modernising beauty products for the Indian market. Lakme’s rise was also rooted in a strong national vision—launched on former Prime Minister Jawaharlal Nehru’s suggestion to reduce foreign exchange spent on imported makeup.

Transforming retail through Trent and Westside

After Lakme was sold to Hindustan Lever Limited in 1966, Simone moved to Trent, where she helped build one of India’s earliest modern retail chains. This later gave birth to Westside, a brand that has become synonymous with contemporary Indian shopping culture.

She also played a key role in philanthropic initiatives, guiding organisations such as the Sir Ratan Tata Institute and supporting cultural and children-focused foundations.

Family, personal life and final farewell

Simone Tata is survived by her son Noel, daughter-in-law Aloo Mistry, and grandchildren Neville, Maya and Leah. She also drew public attention in recent years for being the only member of the Tata family to attend Cyrus Mistry’s funeral, despite the widely known strained ties between the families.

Her funeral will take place on Saturday morning at the Cathedral of the Holy Name Church in Colaba, Mumbai.

Centre orders probe into IndiGo crisis, expects normal flight operations in three days

Amid record cancellations by IndiGo, the Centre has ordered a high-level inquiry and expects flight schedules to stabilise by Saturday, with full normalcy in three days.

The Centre has initiated a high-level inquiry into the massive disruption of IndiGo’s operations, with the government projecting that flight schedules will begin stabilising by Saturday and full normalisation is expected within three days. The announcement comes as cancellations by the airline crossed 500 for the second consecutive day, severely impacting passengers across major airports.

Civil Aviation Minister Ram Mohan Naidu said the government has directed urgent measures to ensure swift restoration of services. Within minutes of his statement, the aviation regulator DGCA announced the formation of a four-member committee to examine the circumstances leading to the delays and cancellations.

DGCA forms committee as cancellations spark scrutiny

The DGCA said IndiGo was given sufficient time to implement revised Flight Duty Time Limitations (FDTL), yet the airline recorded the highest number of cancellations in November. The regulator added that the pattern suggested gaps in the carrier’s internal oversight and preparedness, warranting an independent probe.

The committee will review the sequence of events that triggered disruptions and recommend measures to prevent a recurrence.

Flight duty rules relaxed; minister defends move

Amid criticism from the Opposition and experts, the DGCA temporarily suspended certain FDTL rules, increasing pilot duty limits from 12 to 14 hours. The changes were widely questioned, with allegations that the government was yielding to pressure from IndiGo.

Naidu defended the decision, stating the move was taken solely to safeguard passengers and that safety standards would not be compromised.
He reiterated that passenger care and convenience remain the top priority.

Assurance of refunds, real-time updates, and support

Highlighting steps taken to ease passenger distress, the minister said airlines must:

  • Provide accurate, real-time updates before travellers leave for airports
  • Initiate automatic refunds for cancelled flights without requiring follow-ups
  • Arrange hotel accommodation for passengers stranded for extended periods

Senior citizens and persons with disabilities have been accorded special priority, including access to lounges and additional assistance. Refreshments and essential services are to be provided to all affected travellers.

Inquiry to determine accountability

The government said the high-level probe will identify what went wrong at IndiGo, establish responsibility, and recommend systemic corrections to ensure such disruptions do not occur again.
