How serious is the common cold compared to other illnesses?

The common cold is generally considered to be quite mild compared to other illnesses, making this choice correct. Colds are typically caused by viral infections and lead to symptoms like a runny nose, cough, and sore throat. These symptoms usually resolve without the need for medical treatment and often last only a few days to a week.

In contrast, more serious illnesses, such as the flu or pneumonia, can lead to significant health complications and may require more intensive medical intervention. The common cold does not carry the same risks or severity levels associated with these illnesses, reinforcing the perception of it as a mild condition.

The other options misrepresent the nature of the common cold. It is not worse than the flu or limited to just children; adults can also contract colds. Lastly, the common cold is a viral illness and does not respond to antibiotics, which are effective only against bacterial infections.
