Antibiotics are only for bacterial complications for viral ilnesses.

Flu: The flu is caused by the influenza virus. It can cause nasal congestion, runny nose, fever, nausea, emesis and diarrhea. The common cold can be caused by a variety of different viruses, but the symptoms are usually in the upper airways and don't necessarily cause nausea or emesis or diarrhea. We also have vaccines for the flu. There is no such treatment for common cold.

Overlap but severity: Most people have frequent "cold" which are usually caused by rhinovirus, adenoviruses and others small viruses - the body usually confines these to the upper respiratory tract and usually fights them off in 2-5 days. Over 5-10 days the flu can spread down into the lungs, causes high fevers, muscle pain, joint pain and more rarely lead to severe pneumonia requiring ventilator support and death.
