India's heatwaves worsening, but no one knows how many dying

India's heatwaves worsening, but no one knows how many dying

The Print3 days ago

An investigation by PTI reveals that disjointed, outdated reporting systems are obscuring the true toll, weakening both public awareness and policy action.
'The family rushed him to the hospital,' says Majida Begum, a sanitation worker who witnessed it. 'But he was declared dead on arrival. They had no proof that he died due to heat, so they were not given any compensation.' His death was never officially counted, just one of the countless lives lost in India's intensifying heatwaves that go unrecorded and uncompensated.
New Delhi, Jun 9 (PTI) On a scorching May afternoon last year, a ragpicker in Delhi's Ghazipur area collapsed from heat exhaustion.
Accurate data on heat-related deaths helps identify who is most at risk.
Without it, the government cannot plan effectively, create targeted policies or take timely action to save lives.
But behind the missing numbers are real people, many poor and undocumented, whose deaths routinely slip through the cracks of India's incoherent reporting system.
Currently, at least three separate datasets attempt to monitor heatstroke or heat-related deaths. The two most-commonly cited in the media are maintained by the National Centre for Disease Control (NCDC) under the health ministry and the National Crime Records Bureau (NCRB) under the home ministry.
The India Meteorological Department (IMD) also carries figures on deaths caused by 'heatwaves' in its annual reports, drawing data primarily from media coverage.
However, these three sources report widely-varying numbers.
For instance, data obtained through an RTI query from the health ministry shows 3,812 heat-related deaths recorded between 2015 and 2022 under the Integrated Disease Surveillance Programme (IDSP), managed by the NCDC.
In contrast, NCRB figures, cited in Parliament many times by Union Earth Sciences Minister Jitendra Singh, put the number at 8,171 deaths from 'heat/sunstroke' during the same period.
Meanwhile, the IMD's annual reports record 3,436 deaths due to 'heatwave' between 2015 and 2022.
While the NCDC and the IMD have already released the figures for 2023 and 2024, the NCRB is yet to publish the data for these years.
Since 2015, the health ministry has been collecting data on heat illness and deaths from April to July. In 2019, this was extended to March through July, covering 23 states.
The NCRB has recorded heatstroke deaths since 1995, listing them as 'accidental deaths from forces of nature' since around 2010.
PTI spoke to government officials and healthcare-policy experts to understand the large discrepancies between these datasets.
A senior Delhi Police official explained that the NCRB data largely reflects the number of unattended individuals found dead by police at public spaces, homes and elsewhere.
Such bodies are taken to hospitals where doctors conduct autopsies to determine the cause of death.
According to the NCRB, 730 people died from 'heat/sunstroke' in 2022, 374 in 2021 and 530 in 2020.
By contrast, the NCDC data shows just 33 heat-related deaths in 2022, none in 2021 and four in 2020, as many states failed to report their figures.
These states included Delhi, Uttar Pradesh, Rajasthan, Punjab, Haryana, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, Karnataka, Kerala, Andhra Pradesh, Telangana, West Bengal and Tamil Nadu.
A health ministry official, speaking on the condition of anonymity, said the data from the NCRB and the NCDC are 'not directly comparable' because they originate from different sources.
'The NCDC reports deaths of patients who come to hospital OPDs or are admitted. But if a person dies and is brought for autopsy, that data goes to the forensic medicine department, which may not always share the information with the NCDC,' the official said.
He acknowledged the existence of multiple datasets on heat deaths in India and noted that 'none of those alone gives the full picture'.
'While knowing the actual number of heat deaths is important for policy making, confirming such deaths is difficult even with health ministry guidelines,' he added.
The official said surveillance systems often capture only a fraction of actual cases for other communicable and non-communicable diseases. 'We have some numbers, but never the full picture,' he said.
One major challenge in data collection is the absence of an electronic record system.
'Healthcare facilities still enter data manually. Confirming heat-related deaths is already difficult and manual data entry makes accurate reporting even harder,' said another official.
Though the Integrated Health Information Platform (IHIP) enables digital submission of surveillance data like that of heat-related deaths, the hospital staff manually enter the information into online forms. There is no automated data transfer from hospital records.
Officials also said that while states are mandated to report data, compliance is poor. For example, the hospital staff sometimes omit reporting if temperatures drop due to cloudy weather.
A senior doctor from a central government-run hospital in Delhi, speaking anonymously, said most hospitals are understaffed which hampers proper data collection and timely reporting.
The doctor also alleged that authorities may suppress death figures to avoid compensation liabilities.
At the India Heat Summit 2025 in May, health ministry Advisor Soumya Swaminathan highlighted the weaknesses in the country's death-reporting systems.
'I have been saying this since my time at the Indian Council of Medical Research — death-reporting systems need strengthening because they provide the best source for the government and policymakers to understand causes of death, which should inform policy,' she said.
Abhiyant Tiwari, Lead for Climate Resilience and Health at NRDC India, said attributing deaths directly to heat remains a global challenge, not just in India.
Tiwari, who has contributed to heat action plans at city and district levels, said the all-cause mortality data is more reliable for assessing vulnerability and setting early-warning thresholds, as it captures the total number of deaths during heat events, not only those officially classified as heatstroke deaths.
Many heat-related deaths go unrecorded or are misclassified as heart attacks or other causes. By comparing mortality during heatwaves to normal periods, experts estimate that the excess deaths are likely attributable to extreme heat, he said.
He stressed the need to improve the reporting of the all-cause mortality data and suggested appointing a single department responsible for its collection and dissemination.
As climate change intensifies heatwaves, Avinash Chanchal, deputy programme director at Greenpeace South Asia, called for urgent reforms in how heat-related deaths are recorded.
'Discrepancies between departments and widespread underreporting mean the true toll of extreme heat often remains hidden. The government must understand that hiding or ignoring the true numbers delays the urgent action needed to address heat,' he said.
Until India fixes its fractured data system, the dead will remain just a number or worse, not counted at all, Chanchal said. PTI GVS RC

2 dead, over 500 suffering in diarrhoea outbreak in Odishas Jajpur

Agency: PTI Last Updated: Jajpur/ Bhubaneswar, Jun 11 (PTI) Two persons died and over 500 people are suffering in the diarrhoea outbreak in Odisha's Jajpur district, officials said on Wednesday. A 70-year-old man was declared dead on arrival at the Vyasanagar Hospital, while a 34-year-old died at the Danagadi Community Health Centre, District Collector P Anvesha Reddy said. Among the worst-hit areas are Dharamsala, Jajpur, Danagadi, Korei and Rasulpur blocks, where hospitals are overwhelmed with patients showing gastrointestinal symptoms, officials said. The waterborne disease was initially detected in Dharmasala on Monday night, they said. More than 20 critically ill patients were sent to the SCB Medical College and Hospital in Cuttack, Director of Public Health Nilakantha Mishra said. Health Secretary Aswathy S said a multi-sectoral team has been sent to the district to identify the cause behind the outbreak. A team of doctors have also been sent to the district to ensure proper treatment of patients, while the district administration has also mobilised additional manpower to the hospitals, she said. The collector, meanwhile, visited the hospitals where the diarrhoea patients are undergoing treatment, and urged the people to consume only boiled or disinfected water. Chief District Medical Officer (CDMO) Prakash Chandra Bal said house-to-house surveys were being conducted in the affected villages. 'Accompanied by ASHA and Anganwadi workers, the state-level team is meeting families of patients and collecting water and stool samples to help determine the outbreak's source," he said. ASHA workers, Anganwadi workers and multi-purpose health workers have been supplied with halogen tablets, medicines, ORS packets and awareness materials for distribution among the people, they said. People have been advised to take all precautionary measures and adhere to hygienic practices, they added. PTI COR BBM BBM SOM First Published: June 12, 2025, 01:00 IST

3 more Covid deaths, toll up to 68

New Delhi: India's Covid toll reached 68 on Tuesday with a death each being reported from Delhi, Kerala and Jharkhand. All three victims suffered from co-morbidities. Significantly, the death in Jharkhand is the first reported from the state in the latest Covid wave. In Delhi, tests after the death of a 90-year-old woman with co-morbidities that included chronic kidney disease revealed she also had Covid-19. The victim in Jharkhand was a 44-year-old man, while Kerala saw a 79-year-old man with a history of cardiac and stroke issues succumbing to the infection. In terms of active cases, Kerala continues to be the most affected state, followed by Gujarat, West Bengal and Delhi, according to the health ministry. However, Maharashtra has reported the maximum number of Covid deaths this year. Official sources maintained that most cases are mild and being managed under home care. However, due to the rising number of infections, directives have been issued to all states to check facility-level preparedness and ensure availability of oxygen, isolation beds, ventilators, and essential medicines. The sources said on June 4 that state and district surveillance units under Integrated Disease Surveillance Programme (IDSP) are closely monitoring Influenza Like Illness (ILI) and Severe Acute Respiratory Illness (SARI) cases. "Testing is recommended for all admitted SARI cases and 5 percent of ILI cases as per guidelines and positive SARI samples are being sent for Whole Genome Sequencing through the ICMR VRDL network," they added.

The Digital Shoulder: How AI chatbots are built to ‘understand' you

As artificial intelligence (AI) chatbots are becoming an inherent part of people's lives, more and more users are spending time chatting with these bots to not just streamline their professional or academic work but also seek mental health advice. Some people have positive experiences that make AI seem like a low-cost therapist. AI models are programmed to be smart and engaging, but they don't think like humans. ChatGPT and other generative AI models are like your phone's auto-complete text feature on steroids. They have learned to converse by reading text scraped from the internet. When a person asks a question (called a prompt) such as 'how can I stay calm during a stressful work meeting?' the AI forms a response by randomly choosing words that are as close as possible to the data it saw during training. This happens really fast, but the responses seem quite relevant, which might often feel like talking to a real person, according to a PTI report. But these models are far from thinking like humans. They definitely are not trained mental health professionals who work under professional guidelines, follow a code of ethics, or hold professional registration, the report says. When you prompt an AI system such as ChatGPT, it draws information from three main sources to respond: Background knowledge it memorised during training, external information sources and information you previously provided. To develop an AI language model, the developers teach the model by having it read vast quantities of data in a process called 'training'. This information comes from publicly scraped information, including everything from academic papers, eBooks, reports, and free news articles to blogs, YouTube transcripts, or comments from discussion forums such as Reddit. Since the information is captured at a single point in time when the AI is built, it may also be out of date. Many details also need to be discarded to squish them into the AI's 'memory'. This is partly why AI models are prone to hallucination and getting details wrong, as reported by PTI. The AI developers might connect the chatbot itself with external tools, or knowledge sources, such as Google for searches or a curated database. Meanwhile, some dedicated mental health chatbots access therapy guides and materials to help direct conversations along helpful lines. AI platforms also have access to information you have previously supplied in conversations or when signing up for the platform. On many chatbot platforms, anything you've ever said to an AI companion might be stored away for future reference. All of these details can be accessed by the AI and referenced when it responds. These AI chatbots are overly friendly and validate all your thoughts, desires and dreams. It also tends to steer conversation back to interests you have already discussed. This is unlike a professional therapist who can draw from training and experience to help challenge or redirect your thinking where needed, reported PTI. Most people are familiar with big models such as OpenAI's ChatGPT, Google's Gemini, or Microsoft's Copilot. These are general-purpose models. They are not limited to specific topics or trained to answer any specific questions. Developers have also made specialised AIs that are trained to discuss specific topics, like mental health, such as Woebot and Wysa. According to PTI, some studies show that these mental health-specific chatbots might be able to reduce users' anxiety and depression symptoms. There is also some evidence that AI therapy and professional therapy deliver some equivalent mental health outcomes in the short term. Another important point to note is that these studies exclude participants who are suicidal or who have a severe psychotic disorder. And many studies are reportedly funded by the developers of the same chatbots, so the research may be biased. Researchers are also identifying potential harms and mental health risks. The companion chat platform for example, has been implicated in an ongoing legal case over a user's suicide, according to the PTI report. At this stage, it's hard to say whether AI chatbots are reliable and safe enough to use as a stand-alone therapy option, but they may also be a useful place to start when you're having a bad day and just need a chat. But when the bad days continue to happen, it's time to talk to a professional as well. More research is needed to identify if certain types of users are more at risk of the harms that AI chatbots might bring. It's also unclear if we need to be worried about emotional dependence, unhealthy attachment, worsening loneliness, or intensive use.
