Pulmonary infection refers to infections that affect the respiratory system, particularly the lungs. These infections can be caused by bacteria, viruses, fungi, or parasites and can lead to symptoms such as coughing, chest pain, difficulty breathing, and fever. Common types of pulmonary infections include pneumonia, bronchitis, and tuberculosis. Treatment for pulmonary infections often involves antibiotics, antiviral medications, or antifungal drugs, depending on the underlying cause of the infection. Proper diagnosis and management of pulmonary infections are essential to prevent complications and promote recovery.
