Generally, our first diagnosis is to declare such symptoms belonging to the common cold.

Difference Between Cold and Flu

While both cold and flu are caused by viruses and have many of the same symptoms, their severity is quite different.

A cold usually goes away with an ample amount of rest and a few days’ medications but flu leads to severe illness which can last up to a few weeks.

It can lead to serious health issues such as pneumonia, bronchitis, and sinus or ear infections, and can even turn out to be fatal. 

A common cold is usually associated with a scratchy throat, runny nose, coughing and sneezing, body aches, and headache.

The symptoms of flu, on the other hand, are also accompanied by shaking chills, and fever. While an adult rarely suffers from a fever due to a cold, the flu mostly causes fever in addition to the other symptoms of a cold.
