Chronic Obstructive Pulmonary Disease (COPD)
If you have COPD, which is common in smokers, you may get symptoms that include wet cough because your body is trying to remove some mucus. However, it could be a sign that you have a respiratory infection depending on your symptoms.
For infants and children, viral infections and asthma are the typical causes of wet coughs. Children can also get whooping cough, which has symptoms that are similar to a common cold. Since it can create severe coughing fits, a child can make a whooping noise when they inhale.
