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.

Harivansh set to be elected Rajya Sabha Deputy Chairperson unopposed

Harivansh is set to be elected unopposed as Rajya Sabha Deputy Chairman after no opposition nominations were filed before the deadline.

Published

Former Rajya Sabha Deputy Chairman Harivansh is set to be re-elected to the same post unopposed in the election due to be held later today.
The date has been fixed by the Chairman under the relevant rules governing the conduct of business in the Upper House.
According to sources, the deadline for submitting motions for the election was 12 noon on April 16. A total of five notices were received within the stipulated time, all proposing Harivansh for the post.

Multiple nominations, single candidate
The motions were submitted by members across parties, including Jagat Prakash Nadda, Nitin Nabin, Nirmala Sitharaman, Sanjay Kumar Jha, and Jayant Chaudhary, each backed by seconding members.
All five motions explicitly state that Harivansh be chosen as the Deputy Chairman of the Rajya Sabha.

No opposition nomination filed

Notably, no motion was submitted by the Opposition before the deadline. This effectively clears the path for a unanimous election, as there is no contest for the position.
As per parliamentary procedure, motions will be taken up one by one. Once any one motion is adopted by the House, the remaining motions will not be put to vote.

Likely to be elected by voice vote
In line with established practice, the first motion — expected to be moved by Nadda — may be adopted through a voice vote. Following this, the Chairman will formally declare Harivansh as elected Deputy Chairman.
After the declaration, Harivansh will be escorted to the Chair by members from both the Treasury and Opposition benches, adhering to parliamentary convention.

Amit Shah counters delimitation concerns, says southern states to gain Lok Sabha seats

Amit Shah assures Parliament that southern states will gain Lok Sabha seats after delimitation, countering opposition criticism during the women’s reservation debate.

Published

Amit Shah

Union Home Minister Amit Shah on Thursday addressed concerns over the proposed delimitation exercise, asserting in the Lok Sabha that southern states will not lose representation but instead see an increase in their number of seats.

His remarks came during a heated debate linked to the implementation of women’s reservation, where opposition parties have raised fears that population-based delimitation could reduce the political weight of southern states.

Shah rejected these claims, calling them misleading, and said the proposed framework ensures fairness while expanding the overall strength of the Lok Sabha.

Seat count to rise with expansion of Lok Sabha

The government has indicated that the total number of Lok Sabha seats could increase significantly as part of the delimitation process. In this expanded House, the combined representation of southern states is expected to rise from 129 seats at present to around 195 seats.

Shah emphasised that no state will lose seats in absolute terms, and the exercise is designed to reflect population changes while maintaining balance across regions.

State-wise projections shared in Parliament

During his address, Shah also provided indicative figures for individual southern states, suggesting notable increases in representation. According to the projections:

  • Tamil Nadu could see its seats rise substantially
  • Kerala, Telangana, and Andhra Pradesh are also expected to gain additional seats
  • Karnataka’s representation may increase as well

These figures were presented to counter the argument that delimitation would disproportionately favour northern states.

Political debate intensifies over linkage with women’s quota

The delimitation exercise has been closely linked to the rollout of women’s reservation, which proposes one-third seats for women in Parliament and state assemblies.

Opposition leaders have questioned this linkage, arguing that tying reservation to delimitation could delay its implementation and raise federal concerns. Some leaders have also warned that the move could impact national unity if apprehensions among states are not addressed.

The government, however, maintains that the reforms are necessary to ensure equitable representation and to align the electoral system with demographic realities.

Centre dismisses ‘false narrative’ on southern states

Shah reiterated that concerns about southern states losing influence are unfounded. He said the delimitation process will increase representation across regions and described the criticism as a “false narrative” aimed at creating confusion.

The issue is expected to remain a key flashpoint as Parliament continues discussions on the women’s reservation framework and related legislative changes.

PM Modi assures no discrimination in women’s quota, delimitation debate intensifies in Parliament

PM Narendra Modi has assured that women’s reservation will be implemented without discrimination, amid a heated debate over delimitation in Parliament.

Prime Minister Narendra Modi has assured that there will be no discrimination in the implementation of women’s reservation, as Parliament witnessed a sharp debate over the proposed linkage between the quota and delimitation exercise.

During the ongoing special session, the government reiterated its commitment to ensuring fair representation while addressing concerns raised by opposition parties regarding the timing and structure of the legislation.

The proposed framework aims to reserve 33 percent of seats for women in the Lok Sabha and state assemblies. However, its implementation is tied to a fresh delimitation exercise, which is expected after the next census.

Opposition questions timing and intent

Opposition leaders have raised concerns that linking the women’s quota to delimitation could delay its implementation. They argue that the process of redrawing constituencies may push the actual rollout further into the future.

The issue has triggered a broader political confrontation, with multiple parties questioning whether the move could alter representation across states.

Some critics have also alleged that the delimitation exercise could disproportionately benefit certain regions based on population, a charge the government has rejected.

Government reiterates commitment to fair implementation

Responding to these concerns, the Centre has maintained that the reforms are necessary to ensure accurate and updated representation based on population data.

Leaders from the ruling side have repeatedly emphasized that the process will be carried out transparently and without bias. The assurance that there will be “no discrimination” is aimed at addressing fears among states and opposition parties.

The debate marks a key moment in Parliament, with both sides engaging in intense exchanges over one of the most significant electoral reforms in recent years.
