Rising air pollution in Delhi is fueling an increase in silent pneumonia cases. This condition develops subtly, with mild symptoms like fatigue, breathlessness, and a persistent cough, often mistaken for a common cold. Pollutants like PM2.5 and toxic gases weaken lung defenses, making individuals more prone to infections. Children, the elderly, and those with respiratory conditions are at higher risk. Since silent pneumonia can go undetected until severe, timely diagnosis is crucial. Reducing exposure by wearing masks, improving indoor air quality, and seeking medical attention for prolonged respiratory issues can help prevent complications and safeguard lung health.
