Detailed explanation-1: -A chest cold, or short-term (acute) bronchitis, causes irritation and a buildup of mucus in your lungs. Common colds turn into chest colds when the virus travels from your nose and throat to your lungs. Occasionally, bacteria cause chest colds. You can have a cough with a common cold or a chest cold.
Detailed explanation-2: -A cold is an infection of the upper respiratory system. This just means it can affect the nose, throat, and sinuses. A cold virus gets inside your body and makes you sick.
Detailed explanation-3: -The common cold is a viral infection of your nose and throat (upper respiratory tract). It’s usually harmless, although it might not feel that way. Many types of viruses can cause a common cold. Healthy adults can expect to have two or three colds each year.
