Kerala Floods Highlight a Recurring Health Crisis as Disease Risks Rise

Kerala’s floods are raising concerns over leptospirosis and other infectious diseases as contaminated water, disrupted sanitation and stagnant water increase exposure. Research shows that the health risks can persist for weeks after floodwaters recede, making post-flood disease surveillance critical.

Kerala’s flood emergency is creating another public-health challenge alongside displacement, injuries and infrastructure damage. As people wade through floodwater, clean homes, move through stagnant water or gather in relief shelters, they face exposure to infectious diseases ranging from leptospirosis and dengue to diarrhoeal and respiratory infections.

The risks are emerging as Kerala already carries a substantial communicable-disease burden.

Kerala is India’s Leptospirosis Hotspot

India recorded 8,121 confirmed leptospirosis cases between January and June 2026, according to data tabled in the Rajya Sabha by the Union Ministry of Health and Family Welfare. More than half, 4,340 cases, or 53.4% — came from Kerala, Tamil Nadu, Karnataka, Andhra Pradesh and Telangana.

Kerala recorded the highest number at 1,726 cases, followed by Tamil Nadu with 1,473 and Karnataka with 624. Assam reported 786 cases and Maharashtra 780.

The figures place Kerala at the top of the national list even before the current flood emergency. That is significant because leptospirosis is strongly associated with exposure to contaminated water and soil — conditions that become more common during floods and the recovery period.

Floods Create Multiple Disease Pathways

Flooding does not produce one uniform disease pattern. Different infections emerge through different pathways and at different times. A 2026 systematic review in BMC Infectious Diseases, covering 71 studies published between 2014 and 2024, found consistent links between flooding and waterborne infections including leptospirosis, cholera, bacillary dysentery and hepatitis A/E. It also identified increased risks of vector-borne diseases such as dengue and malaria. Disease emergence varied from days to weeks depending on the pathogen and flood conditions.

The evidence is particularly strong for diarrhoeal disease. A meta-analysis of 42 studies found that floods were associated with a 40% higher risk of infectious diarrhoea, with the risk of bacterial diarrhoea increasing by 82%. For Kerala, this matters because diarrhoea was already one of the state’s most frequently reported communicable diseases.

During the first eight days of July 2026, government hospitals reported 19,428 diarrhoeal cases, alongside 84,658 fever cases. The same period recorded 834 dengue cases, 661 influenza cases, 113 leptospirosis cases, 197 jaundice cases, 56 malaria cases and 34 Shigella cases. Thirty people died from communicable diseases during those eight days.

Kerala’s Floods Offer a Warning

Kerala’s own experience shows why disease surveillance must continue after the rain stops. A study comparing leptospirosis in Kerala during 2017, 2018 and 2019 found higher case numbers in the flood years, with the strongest increase following the severe 2018 floods. Importantly, cases were highest during the post-flood period, indicating a time lag between flooding and disease emergence.

2018 floods identified 61 leptospirosis hotspots, compared with 34 in 2017 and 21 in 2019. Several hotspots overlapped with high flood-risk areas, while others were in places with limited access to hospitals. The finding points to a larger preparedness opportunity: flood-risk mapping could be combined with disease-risk mapping to identify communities that need early warnings and preventive interventions.

Why Leptospirosis is a Particular Concern

Leptospirosis is caused by Leptospira bacteria and is commonly transmitted through contact with water or soil contaminated by infected animal urine, particularly from rodents. Floods increase this exposure as people walk through contaminated water, clean flooded homes or handle mud and debris. The risk can continue after water recedes, when residents return to clean houses and remove waste.

Kerala has developed specific responses for this risk. The state’s health system uses doxycycline prophylaxis for selected high-risk exposures and has previously established dedicated “Doxy Corners” during disaster responses. It has also expanded early diagnosis: RT-PCR testing for leptospirosis is available through nine government laboratories, according to the Health Department.

The challenge is ensuring these measures reach exposed populations quickly enough.

Dengue and Diarrhoeal Diseases May Follow Different Timelines

Dengue presents a different risk. Heavy rainfall can initially wash away mosquito breeding sites, but as floodwater recedes, stagnant pools can remain in containers, drains and construction sites. These can become breeding sites for Aedes mosquitoes.

Kerala had already recorded 834 dengue cases in the first eight days of July, so vector surveillance will remain important as the flood situation evolves. Diarrhoeal diseases can emerge through another pathway. Flooding can damage sanitation infrastructure, contaminate water and disrupt food hygiene. Kerala’s 19,428 diarrhoeal cases in eight days provide a reminder that this risk exists independently of leptospirosis.

The state’s existing disease burden also includes Shigella. By June 23, Kerala had reported 241 Shigella infections, with outbreaks identified in Kozhikode, Wayanad, Thrissur and Alappuzha.

Influenza Adds Another Layer

Respiratory infections are less directly connected to floodwater but can become harder to control when people are displaced. Relief camps bring people from different households into shared spaces. Crowding and inadequate ventilation can increase opportunities for respiratory transmission.

Kerala recorded 661 influenza cases during the first eight days of July. The concern is about vulnerability. Children, older adults and people with underlying illnesses may be at greater risk when respiratory infections spread in crowded shelters and routine healthcare is disrupted.

The Health Emergency May Peak After the Flood

The most important lesson from Kerala’s previous floods is that the health emergency does not necessarily end when the water recedes. The immediate risks include injuries, drowning and direct exposure to contaminated water. Later, people face contaminated mud and waste while cleaning homes, stagnant water that can support mosquito breeding, disrupted sanitation and increased contact in temporary shelters.

Research shows that different infections can emerge over different time lags. For leptospirosis, Kerala’s experience suggests that the post-flood period can be particularly important. That makes the weeks after flooding a crucial test of public-health preparedness.

Kerala already has daily disease surveillance, district-level monitoring, leptospirosis testing and preventive protocols. The next step is to connect these systems more closely with flood-risk information so that authorities can identify potential disease clusters before hospitals begin seeing a large increase in patients.

FSSAI Moves to Restrict Added Sugars in Infant Foods, Citing Need for Stronger Nutritional Safeguards

FSSAI has proposed restricting the addition of sucrose and fructose to infant foods for babies up to six months. The draft amendment aims to strengthen nutritional safeguards.

The first months of life leave little room for nutritional guesswork. An infant’s food must supply the energy and nutrients needed for growth, making the composition of commercial infant nutrition products a matter of public health. Whether manufacturers need to add particular sugars to these products is therefore an important regulatory question.

Research published in recent years has begun examining how added sugars enter infants’ diets, including through formula milk, and whether early exposure is associated with subsequent eating patterns and weight gain. Although the evidence does not establish that added sucrose or fructose in infant formula directly causes obesity, it has raised questions about the nutritional value of adding sugars when alternative carbohydrate sources are available.

Against this backdrop, the Food Safety and Standards Authority of India (FSSAI) has proposed prohibiting the addition of sucrose and fructose to food products intended for infants up to six months of age. The draft amendment, published in the Gazette of India on 16 October 2026, would tighten the existing rules governing the composition of these products.

Early Exposure to Added Sugars

An Indian study published in the Indian Journal of Community Medicine in 2021 examined the sugar and salt content of 114 commercially available infant formulas and baby foods. The researchers found that around 28% of the products had a high-sugar profile, while approximately 51% listed sugar or related ingredients among their first four ingredients.

The study covered products intended for children aged up to 24 months, including infant formulas and complementary foods. Its findings offer evidence that sugar content warrants scrutiny in India’s infant and young-child food market. However, the assessment relied on product labels and did not establish whether the products caused adverse health outcomes. It also did not demonstrate that infant formulas intended specifically for babies under six months routinely contained added sucrose or fructose.

Research elsewhere has examined possible links between added sugars in infant formula and early growth. A 2025 study published in The Journal of Nutrition followed 234 infants from predominantly low-income households in the United States. Researchers assessed dietary intake at six, nine and 12 months and found an association between higher added-sugar intake from formula and higher weight-for-length scores.

For every additional 10 grams of added sugar consumed daily through formula, weight-for-length scores increased by an average of 0.060. The study was observational, so it cannot establish that sugar caused the difference. Its findings also cannot be directly generalised to Indian infants.

A separate study published in Frontiers in Nutrition in 2023 examined dietary data from 95 infants and toddlers aged nine to under 16 months. It found an association between added sugars consumed through infant formula and sugar-sweetened beverage consumption later in infancy. The researchers did not establish a significant association between formula-derived added sugars and added-sugar intake from table foods. The small sample and cross-sectional design limit the conclusions that can be drawn.

These studies examine different aspects of early sugar exposure: the composition of products available in India, associations with infant weight and possible links with later dietary patterns. None establishes that the proposed restriction will prevent childhood obesity. They do, however, provide grounds for examining whether particular sugars need to be added to products intended for very young infants.

Infant’s Food: Why the First Six Months Matter

The World Health Organization (WHO) and UNICEF recommend exclusive breastfeeding during the first six months of life, followed by the introduction of appropriate complementary foods at around six months while breastfeeding continues.

For infants who require an alternative to breast milk, appropriately formulated infant formula can provide essential nutrition. Its carbohydrate composition must meet nutritional requirements for growth and development. The question for regulators is whether adding particular sugars serves a necessary nutritional purpose in products designed for this age group.

WHO’s 2023 guideline on complementary feeding recommends that children aged six to 23 months should not consume foods high in sugar, salt and trans fats. Its evidence review identified associations between sugar-sweetened beverage consumption during infancy and later obesity in some studies, although the certainty of the evidence was low. The recommendation concerns the broader diet of children aged six months and older; it does not specifically establish the effects of sucrose or fructose in infant formula.

The distinction between naturally occurring sugars and added sugars is equally important. Milk naturally contains lactose, which provides energy. Sucrose and fructose may instead be introduced as ingredients during product formulation. Their use needs to be assessed against the nutritional requirements of the intended age group.

What the FSSAI Amendment Proposes

Under the Food Safety and Standards (Foods for Infant Nutrition) Regulations, 2020, lactose and glucose polymers are the preferred carbohydrate sources in infant nutrition products. The existing rules permit sucrose and/or fructose when required as a carbohydrate source, subject to prescribed limits.

The draft Food Safety and Standards (Foods for Infant Nutrition) Amendment Regulations, 2026, proposes prohibiting the addition of sucrose and fructose to products intended for infants up to six months of age. This would remove the existing allowance for these two sugars in products for this age group. FSSAI has invited objections and suggestions from stakeholders within 60 days from the date on which copies of the relevant Gazette notification are made available to the public. The submissions will be considered before the amendment is finalised.

The National Medical Commission (NMC) has directed medical colleges and medical institutions across India to establish Patient Safety Committees or Cells and designate Patient Safety Nodal Officers to strengthen safety practices and reduce preventable harm in healthcare settings.

The Commission asked the heads of medical institutions to share the composition of their committees and the details of the designated nodal officers with the National Patient Safety Secretariat (NPSS) under the Directorate General of Health Services (DGHS).

The directive follows a communication dated May 8, 2026, from the Additional Director General of Health Services in the Union Ministry of Health and Family Welfare. It seeks to strengthen the adoption of patient safety protocols and standard operating procedures across medical institutions.

NMC’s Multidisciplinary Oversight

The proposed committee will be chaired by the director, head of the institution or medical superintendent. Its membership must include representatives from relevant medical specialties and the patient safety domains identified by the NPSS. Institutions are also advised to designate a nodal officer with sufficient seniority and authority to coordinate safety initiatives.

The framework covers 11 patient safety domains, including medication safety, surgical safety, blood transfusion safety, medical device safety, laboratory and diagnostic safety, infection prevention and control, healthcare-associated infections, antimicrobial resistance, patient and family engagement, vaccine and injection safety, and facility safety. It also encompasses operational research in patient safety and safety in AYUSH services.

The scope extends beyond clinical treatment to areas such as biomedical waste management, fire safety, structural safety and environmental safety. Nursing, hospital administration and other relevant professionals can contribute to the committee’s work.

From Protocols to Institutional Accountability

The directive places responsibility for patient safety within an organised institutional framework. Rather than leaving safety measures to individual departments or healthcare professionals, the proposed mechanism brings clinical, diagnostic and administrative functions under coordinated oversight.

The committee’s terms of reference include reviewing patient safety incidents and near misses, analysing their causes, promoting reporting and recommending corrective and preventive measures. Such reviews can help institutions identify weaknesses in procedures and address risks before they result in further harm.

The effectiveness of these committees will depend on how consistently institutions implement safety protocols, review incidents and act on their findings. Establishing a committee is an administrative step; sustained monitoring and corrective action are essential to translating the framework into safer care.

World Food Day: India’s Childhood Obesity Burden Raises Concerns Over Diabetes Risk

More than 41 million Indian children and adolescents aged 5–19 were living with overweight or obesity in 2025, according to the World Obesity Atlas 2026. The growing burden raises concerns about long-term health risks, including type 2 diabetes, and highlights the need for healthier food environments, better nutrition and stronger school-based interventions.

With more than 41 million Indian children and adolescents living with overweight or obesity, experts warn that unhealthy food environments could increase future risks of type 2 diabetes. New national guidance on childhood diabetes and proposed restrictions on junk food sales near schools highlight the need for preventive action.

As the world observes World Food Day on October 16, childhood nutrition is emerging as a challenge that extends beyond hunger and undernutrition. The growing prevalence of overweight and obesity among children is raising concerns about their long-term health, including their risk of developing type 2 diabetes.

India faces a particularly significant challenge. The World Obesity Atlas 2026 estimates that approximately 14.9 million children aged five to nine and 26.4 million children and adolescents aged 10–19 in India were living with overweight or obesity in 2025. Together, these figures amount to more than 41 million young people.

The report also estimates that around 1.39 million Indian children aged five to 19 had hyperglycaemia attributable to high body mass index in 2025. Hyperglycaemia refers to elevated blood glucose levels and is a health indicator associated with metabolic risk; it should not be interpreted as a count of children diagnosed with diabetes.

The figures highlight the importance of addressing childhood obesity early, before associated health risks become more difficult to manage.

Food environments and the risk of early-onset diabetes

The World Health Organization (WHO) reported in September 2026 that 400 million children and adolescents aged five to 19 worldwide were overweight in 2024, including 170 million living with obesity. The prevalence of overweight in this age group increased from 8% in 1990 to 20% in 2024.

Childhood obesity is influenced by a combination of biological, social, economic and environmental factors. Diets high in energy but low in essential nutrients, limited opportunities for physical activity and the easy availability of heavily marketed processed foods can contribute to unhealthy weight gain.

Obesity can increase insulin resistance, in which the body’s cells respond less effectively to insulin. This can raise the risk of type 2 diabetes, a condition that is increasingly important to consider in children and adolescents.

However, the relationship between food and diabetes requires an important distinction. Type 1 diabetes is an autoimmune condition in which the body’s immune system attacks insulin-producing cells in the pancreas. It is not caused by eating sugary foods or being overweight. Type 2 diabetes develops through different mechanisms and is associated with factors including excess body weight, genetics and physical inactivity.

The two conditions require different approaches to prevention and treatment.

India introduces a national childhood diabetes framework

In a significant policy development, the Union Ministry of Health and Family Welfare released a comprehensive guidance document on diabetes mellitus in children on May 3, 2026.

The framework outlines a structured approach to screening, diagnosis, treatment and long-term management, linking community-level identification with district hospitals and medical colleges. It also provides for free-of-cost care at public health facilities, including insulin therapy, blood glucose monitoring supplies and follow-up services.

The guidance promotes awareness of the early warning signs of type 1 diabetes through the “4Ts”: Toilet, Thirsty, Tired and Thinner. These refer to frequent urination, excessive thirst, unusual tiredness and unexplained weight loss.

The initiative is important because timely diagnosis and access to insulin can be lifesaving for children with type 1 diabetes. It also highlights the need for health systems to identify and manage diabetes before complications develop.

Schools become a focus of food policy

India is also considering measures to improve the food environments surrounding schools. A Reuters report published on September 24, 2026, said the country was moving towards restrictions on the sale of foods high in fat, salt and sugar within a 50-metre radius of schools.

The proposed measures would affect vendors and shops selling products such as sugary drinks and packaged snacks near educational institutions. The proposal reflects growing concern about the availability of unhealthy foods in places where children spend much of their day.

If implemented effectively, school-focused measures could form part of a wider strategy that includes healthier school meals, accessible drinking water, nutrition education, physical activity and clearer food labelling.

However, restrictions alone cannot address the problem. Families also need affordable access to fruits, vegetables, pulses and other nutritious foods. Public-health measures must account for household budgets and the realities of food access in different communities.

Beyond calories

World Food Day 2026, themed “Innovate today. Nourish tomorrow,” offers an opportunity to reconsider what food security means for children. Access to sufficient calories is essential, but the nutritional quality of food also matters.

Reducing the future burden of type 2 diabetes requires action across healthcare, education, food policy and community environments. At the same time, children living with type 1 diabetes need timely diagnosis, uninterrupted insulin supplies and long-term medical support
