Viral Infection
When you are attacked by viruses or bacteria, an infection would occur and cause a dry or wet cough. This condition might last a few days to a few weeks, depending on the exact strain. The main reason is that these foreign components would irritate your airways and force you to cough as a way of eliminating mucus. It requires a lot of patience and time to treat this form of cough. If left untreated, the problem might progress and trigger other issues in your respiratory system. [9]
