Cold and Flu Symptoms Compared – What is the Difference?
Each symptom has a specific cause associated either with a cold or the flu, or sometimes both. It’s important to remember that symptoms will vary from person to person.
Cold: As mucus travels down your throat and your body attempts to deal with the virus in your respiratory system, you may start to cough. This cough will usually be productive (or ‘wet’), meaning you produce phlegm.
Flu: A ‘wet’ cough is also a common symptom of the flu.

Cold: Mild chest congestion can often be a symptom of a cold. It happens when your mucus membranes (which intercept irritants like cold and flu viruses) become irritated. When this occurs, the membranes produce additional mucus, to help your body trap and get rid of the virus. This extra mucus then builds up in your airways and causes chest congestion.
Flu: You may also experience chest congestion with the flu, however it will likely be more severe.
