GRAP IV Reimposed In Delhi

The Commission for Air Quality Management (CAQM) imposed Stage IV of the Graded Response Action Plan (GRAP) on Saturday evening after AQI crossed the 400 mark for the first time in 2026. GRAP-IV is the strictest of all measures, and bans construction activities, along with restrictions on vehicle movement.

What Is Allowed And What Is Not

Under GRAP-IV, all petrol, diesel and CNG stations in Delhi will supply fuel to only vehicles with valid Pollution Under Control Certificate (PUCC).

Vehicles identified through ANPR cameras or other methods and found refuelled without PUCC will be facing penalties.

Verification of the physical certificates or electronic certificates would be done through systems like VAHAN.

Note: These rules do not apply on emergency vehicles on sovereign duty like ambulances, fire tenders and police vehicles. Vehicles carrying essential goods or providing essential services will be exempted too, notified by authorities.

Any vehicle registered outside Delhi and not compliant with BS-VI norms will not be allowed to operate in the city. CNG and electric vehicles, public transport, and vehicles carrying essential goods are exempted.

Trucks or any other carriers that transport construction materials like sand, stones, bricks, cement, ready-mix concrete, debris and similar items, will not be allowed to enter Delhi.

Are Schools Closed Under GRAP-IV?

Under GRAP-IV, physical classes are suspended, and based on previous precedents, educational institutions were directed to shift to online or hybrid learning mode. GRAP-IV restrictions have been reimposed across Delhi and NCR residents, including Gurugram, Faridabad, Ghaziabad, and Gautam Budh Nagar.

Delhi's Air Pollution Continues To Worsen

Delhi is not just breathing toxic air, but also a superbug through its air, which was found in a latest research conducted by the researchers are Jawaharlal Nehru University, published in Nature - Scientific Reports. Apart from the heavy particulate matter or the PM2.5, which are small enough to penetrate through one's bloodstream and cause blockage, Delhi's air also contains airborne bacteria, including staphylococci. The bacteria levels exceed the safety limit by 16-fold as provided by the World Health Organization (WHO).

Will Delhi Use Smog-Eating Surfaces To Deal With Pollution?

The government is pursuing "smog eating" surfaces to deal with the pollution problem in Delhi. While it may sound like a strange thing in India, not to the world. In fact, in the Netherlands these were used to reduce local nitrogen oxide or the NO concentrations in the air, rather than greenhouse gas concentrations.

Smog usually contains a mixture of hydrocarbons, ozone, oxides of nitrogen and sulphur, and particulates. The pollution is caused by both photochemical reactions that involve sunlight, unburned hydrocarbons and nitrogen oxides, along with high concentrations of particulate matter, especially from vehicle exhaust, construction dust and biomass burning.

Environment Minister Manjinder Singh Sirsa announced "smog eating" surface as part of its pollution control plan, for which the government has also signed an MoU with IIT Madras.

The smog eating surfaces will be public surfaces coated with photocatalytic materials like titanium dioxide or TiO2 that is used to degrade pollutants.

Smog contains mainly nitric oxide, nitrogen dioxide, sulphur dioxide, ozone, and particulate matter. When all of these interact with photocatalytic materials, gaseous pollutants convert into less harmful compounds, such as nitrogen oxides become nitrates or decompose into ions. This process is also known as pollutant mineralization.

All India Institute of Medical Sciences (AIIMS) and the Indian Space Research Organisation (ISRO) signed a Memorandum of Understanding (MoU) on Monday to collaborate on advancing research in space medicine.

The MoU was signed between M Srinivas, Director (AIIMS), New Delhi and Dinesh Kumar Singh, Director, Human Space Flight Centre (HSFC), ISRO.

What Do We Already Know About Space Medicine?

As per a 2017 study in the British Journal of Anaesthesia, space medicine is fundamental to the human exploration of space. It supports survival, function and performance in this challenging as potentially lethal environment. It is international, intercultural and interdisciplinary, operating at the boundaries of exploration, science, technology and medicine.

Space medicine specialists play a crucial role in safeguarding astronauts and other spaceflight participants. Known as “flight surgeons,” they help develop strategies to protect the health, safety, and performance of space travellers in the extreme conditions of space. Their responsibilities span every stage of a mission — from selection and training to in-flight care, post-mission rehabilitation, and monitoring long-term health effects.

Sick days are again piling up with a respiratory disease, not COVID-19 or the flu. This disease is most likely the one Americans have not heard of. This is HMPV or human metapneumovirus. Doctors have asked people to stay vigilant as seasonal flu virus could lead to pneumonia and bronchitis, and it is spreading in California wastewater and around the country. However, as per public health officials, there is nothing to get worried at this point.

As per the public database WasterwaterScan Dashboard, high levels of HMPV were detected across Northern California cities. The highest levels were reported in Redwood City, whereas elevated levels were found in San Francisco Bay Area and Napa's Wine Country. What's more dangerous is that this virus is without a vaccine.

The good news is that in other parts of country HMPV remains lower. However, the Centers for Disease Control and Prevention (CDC) noted that data from October 2025 shows the cases are trending up, especially during winter and spring.

Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic, as reported by The Independent said, "In the late winter, early spring, it can account for five percent to 10 percent of all the respiratory infections that we diagnose in the United States. So it's definitely out there." Experts explain that other viruses like HMPV or influenza get a chance when COVID is quieter.

Virus Without A Vaccine: What Is HMPV?

HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).

HMPV most likely spreads from an infected person to others through:

• the air by coughing and sneezing
• close personal contact, such as touching or shaking hands
• touching objects or surfaces that have the viruses on them, then touching the mouth, nose, or eyes

In the US, HMPV circulates in predictable patterns each year, typically beginning in winter and lasting through spring.

The usually self-limiting and mild symptoms typically last 4 to 5 days. These include:

• cough
• fever
• nasal congestion
• shortness of breath

People at risk include:

• elderly people
• children
• people with comorbidities

"The HMPV is not deadly, and there is no evidence of mortality or a severe transmission rate," former Indian Council of Medical Research (ICMR) scientist, Dr. Raman Gangakhedkar, told IANS, during the virus's outbreak in India in 2025.

“The virus may cause pneumonitis-like illness, but the mortality rates are almost unknown so far. HMPV has a global prevalence of about 4 per cent,” he added.

While no vaccine or treatment can prevent HMPV infection, to avoid the infection, individuals must:

Practice good hygiene and cover your mouth and nose with a tissue when coughing or sneezing, or use your elbow, not your hands, for it. And wash your hands properly, especially in healthcare settings.

Why Are People Hearing About The Virus Without Vaccine Now?

The reason people have not heard about it before is because its symptoms are nearly indistinguishable from other respiratory infections, so often it could go undiagnosed. Furthermore, earlier the COVID cases and influenza cases sparked up, which deviated the attention from HMPV. Now, with the season gone, and increased awareness around respiratory illnesses, greater attention to viruses like HMPV is also paid.

One in seven Indians, or over 14 percent of the population, suffers from some form of mental health disorder. Amid an increasing treatment gap -- up to 90 percent -- seen in several states, especially in North India, the government today reiterated the plan of launching a second National Institute of Mental Health and Neurosciences (NIMHANS) in the northern states.

NIMHANS-2 was first announced by Finance Minister Nirmala Sitharaman during the Union Budget 2026-27, to deliver specialized care for mental health and neurological disorders in north India.

Health experts and policymakers, as part of the government-led Post-Budget Webinar series, highlighted the growing burden of mental and neurological disorders in India and also stressed the urgent need to strengthen institutional capacity to meet emerging healthcare demands.

"One in seven Indians is affected by mental health disorders, while several states continue to face a treatment gap ranging from 70 to 90 percent," the experts said.

Noting that Non-Communicable Diseases (NCDs) account for over 60 percent of deaths in the country, they added that "neurological and mental health conditions are among the leading contributors to disability-adjusted life years (DALYs)," among the citizens.

Need For Tertiary Neuro-psychiatric Care

To address these, the experts called for ramping up tertiary mental health institutions and expanding specialized services.

The session, moderated by Vijay Nehra, Joint Secretary, Ministry of Health and Family Welfare, highlighted that North India currently lacks adequate tertiary neuro-psychiatric care facilities. These include areas such as:

• advanced neuroimaging,
• neurocritical care,
• specialized neurological services

Further, making a virtual address at the Post-Budget Webinar, Union Health Minister JP Nadda also highlighted the government’s focus on strengthening mental healthcare services in the country.

"NIMHANS-2 will be established in North India to expand advanced clinical care, training, and research," Nadda said.

"In addition, the Central Institute of Psychiatry, Ranchi, and the Lokopriya Gopinath Bordoloi Regional Institute of Mental Health, Tezpur, will be upgraded as regional apex institutions to strengthen mental healthcare services in the eastern and north-eastern regions," he added.

Meanwhile, the experts also stressed the need to improve services in underserved and geographically remote regions, including the northeastern states, through better infrastructure, capacity building, and targeted deployment of trained mental health professionals.

They also discussed strategies for expanding advanced neuro-psychiatric care and reinforcing India’s overall mental healthcare ecosystem. They proposed:

• Adopting a hub-and-spoke model supported by digital health platforms

This would allow tertiary institutions and centers of excellence to provide technical guidance, specialist consultations, and clinical support to district hospitals and community-level health facilities.

"Such a model would strengthen referral pathways and ensure that specialized mental health services are accessible to people even in remote and rural areas," the experts said.

• Integrating services under Tele-MANAS

Both existing and upcoming campuses of NIMHANS must be integrated , as this will enable a robust nationwide tele-mental health network that ensures

• timely counselling,
• psychological support,
• specialist consultations

• Digital follow-up systems

The experts called for the seamless integration of healthcare facilities, aligned with the vision of the Ayushman Bharat Digital Mission and the ABHA ID ecosystem. This, they said, will

• enable continuity of care,
• Improve monitoring of patients,
• Lead to better clinical outcomes

• A national Brain-Mind Cloud Network

The Network proposed under the National Health Mission would connect premier institutions such as All India Institute of Medical Sciences (AIIMS), state medical colleges, and primary healthcare centers through a digitally integrated platform.

It could also facilitate

• unified mental health records,
• AI-based screening tools,
• data-driven clinical decision support systems,
• tele-neuro-psychiatric hubs at regional centers.
