While many respiratory infections resolve with routine treatment, some can progress deeper into the lungs and develop into serious conditions such as pneumonia. A cough that refuses to settle, returning fever and worsening breathlessness should never be dismissed.
Lung infections occur when bacteria, viruses, fungi or other microorganisms infect the respiratory system and cause inflammation within the lungs. Pneumonia is one of the most common and potentially serious forms, affecting the air sacs of the lungs and making breathing difficult. Prompt diagnosis is essential, especially in children, the elderly, smokers and patients with existing conditions.
At Healthy Chest & Sleep Clinic, Dr. Vishal Sharma provides expert diagnosis and treatment for lung infections, helping patients recover faster while preventing complications and long-term lung damage.
