More than 200,000 cases of acute respiratory illnesses were recorded in six state-run hospitals in Delhi between 2022 and 2024 as the Indian capital struggled with rising pollution levels, the federal government has said.

The government stated in parliament that more than 30,000 individuals suffering from respiratory illnesses had to be hospitalized during this time frame.

Toxic air is a recurring issue in Delhi and its suburbs, especially during winter months. The Air Quality Index (AQI) has been reported to be over 20 times the limit recommended by the World Health Organization.

Reasons attributed to this alarming situation include a combination of industrial emissions, vehicle exhaust, dropping temperatures, low wind speeds, and the seasonal burning of crop stubble in neighboring states.

Delhi's six major hospitals reported 67,054 acute respiratory cases in 2022, rising to 69,293 in 2023, and then slightly declining to 68,411 in 2024. This trend indicates a worrying correlation between pollution levels and increased hospital admissions.

On an average day, Delhi's AQI frequently exceeds the severe threshold of 400, particularly during the winter season, posing severe health risks to the entire population, especially those with pre-existing conditions. As of this week, the average AQI was recorded at approximately 380.

In response to the ongoing crisis, Delhi's high court is evaluating urgent measures to combat hazardous air pollution, while India’s top court has also expressed concerns regarding the deteriorating air quality in the capital and surrounding regions.
