Does every cough indicate an infection?
Often, coughing is only a natural reflex to help expel foreign bodies or liquid that have come into our airways, for example by swallowing the wrong way. In this way, coughing helps to clear the bronchi. However, cough may also be a warning signal from the bronchi, indicating an infection of our respiratory tract. It often arises with diseases like common cold, acute or chronic bronchitis and asthma.
