Prominent health officials are sounding alarm over Delhi's worsening air quality, citing a notable surge in hospital admissions for respiratory ailments. The national capital's Air Quality Index has crossed the 400-mark, placing it in the severe category and prompting health institutions to prepare for a further spike in patient numbers.

Medical professionals from leading healthcare institutions report approximately 20 percent rise in respiratory cases as pollution levels intensify across the metropolitan region. Patients presenting with asthma exacerbations, bronchitis, and other breathing difficulties have strained hospital capacity in recent days, signaling the immediate health toll of hazardous air conditions.

The timing coincides with Diwali festivities, traditionally accompanied by increased firecracker emissions that compound existing air pollution. Health experts are urging residents, particularly vulnerable groups including children, elderly citizens, and those with pre-existing respiratory conditions, to take preventive measures and limit outdoor exposure.

Authorities have been advised to monitor air quality developments closely and ensure medical facilities are adequately resourced to manage the anticipated patient influx. Public health interventions focusing on awareness and protective measures are being emphasized as the pollution season intensifies across northern India.
