Delhi has fallen under a choking cloud of pollution. More than 200,000 people sought care for acute respiratory illnesses in six state-run hospitals between 2022 and 2024, and officials warn the surge is not just a spike in numbers but a signal of a city under siege by toxic air. The air quality index has repeatedly crossed the severe threshold, sometimes more than 20 times the World Health Organization’s recommended limit. In winter, this is a recurring crisis.
The government data show a heavy toll: 67,054 ARI cases in 2022, 69,293 in 2023, and 68,411 in 2024 among patients attending major hospitals. Officials cautioned that while higher pollution coincides with more ER visits, the study design cannot definitively prove causation. The causes are multifaceted: industrial emissions, vehicle exhaust, dropping temperatures, low wind speeds, and seasonal burning of crop stubble in neighbouring states.
The health impact is immediate: crowded emergency rooms, rising hospital admissions, and heightened risk for children and people with respiratory or cardiovascular conditions. While the judiciary in India has pressed for urgent pollution-curbing measures, experts warn that long-term mitigation requires a sustained, multi-sector approach: tighter emissions controls, cleaner transportation, and regional coordination to reduce cross-border pollution.
