A natural reflex, cough helps to clear up the throat and lungs of irritants. Usually, occasional dry cough is not a cause for concern. However, a persistent increase in coughing can be a signal of an underlying medical condition that can be more serious. Cough which does not have any phlegm or mucus, is called dry cough or tickly cough. These are usually referred to as non-productive coughs by the doctors while wet cough called productive cough brings up phlegm which helps in clearing the airways of irritants. A medical condition classifies to be acute or chronic if a cough lasts for more than eight weeks. If it is associated with a cold or the flu, then it tends to last a week or two at most and clear up within three weeks mostly. However, if anyone had a viral illness, then the post-viral cough may last for several (up to about 8) weeks, while some coughs continue for longer and are usually a sign of a severe underlying problem.
A cough which lasts for more than eight weeks is a chronic (ongoing) persistent cough in adults. However, if it lasts 2 to 4 weeks in children, then it is called a prolonged acute cough.
