Delhi’s Toxic Air Crisis: Over 2 Lakh Acute Respiratory Cases Reported in 6 Major Hospitals Over 3 Years

Delhi's worsening air quality has once again come under national spotlight after new data presented in Parliament revealed the alarming scale of respiratory illnesses in the capital.

According to the Union Ministry of Health and Family Welfare, six major central hospitals reported 2,04,758 acute respiratory illness (ARI) cases in emergency departments between 2022 and 2024. Nearly 30,420 of these patients required hospitalisation, highlighting the intensifying severity of pollution-linked health complications.

Hospitals See Consistent Influx of Respiratory Patients

The data shared by Minister of State for Health and Family Welfare Prataprao Jadhav was submitted in response to Rajya Sabha MP Dr. Vikramjit Singh Sahney's queries on the rising burden of respiratory diseases in polluted urban regions. He sought details on trends in asthma, COPD, lung infection cases, and whether the government was assessing pollution's role in aggravating respiratory health.

A year-wise review of the six hospitals that include AIIMS, Safdarjung, LHMC group, RML, NITRD, and VPCI shows a consistent flow of emergency cases:

2022 saw 67,054 cases with 9,874 admissions.
2023 saw 69,293 cases with 9,727 admissions.
2024 saw 68,411 cases with 10,819 admissions.

Despite a slight reduction in emergency visits in 2024, admissions rose significantly, pointing to worsening severity among those who did seek care.

Government Admits Pollution Is a Triggering Factor

The Centre acknowledged that "air pollution is one of the triggering factors for respiratory ailments and associated diseases" while noting that several elements, including occupation, socio-economic conditions, diet, and underlying health issues, shape overall outcomes.

A multi-city study by the Indian Council of Medical Research offered further evidence, examining over 33,000 cases across five locations. The findings showed a clear association between pollution spikes and increased emergency room footfall for respiratory problems although the study did not establish direct causation.

Surveillance Network Expands, Response Still Struggles

The National Centre for Disease Control has widened digital tracking of pollution-related illnesses under the Integrated Health Information Platform since August 2023. More than 230 sentinel sites across 30 states and union territories are now covered including six in Delhi.

Under the National Programme on Climate Change and Human Health, an annual advisory is issued urging states to boost preparedness, train medical staff, maintain essential drug stocks, and spread public alerts when AQI levels deteriorate. The 2025 advisory, released in April, reiterated the same measures.

Capital Braces for Another Hazardous Winter

Although advisories are released every year, Delhi continues to grapple with the recurring mix of vehicle emissions, dust, construction activity, and seasonal farm fires that fuel its winter smog. The emergency rooms continue to see the consequences.

As the national capital moves into another pollution-heavy season, the recent parliamentary data lays bare the scale of the crisis. With more than two lakh emergency visits over three years, Delhi's struggle with toxic air remains a pressing public health emergency.
