What is the difference between a cold and influenza?
Influenza and the common cold are both respiratory illnesses but they are caused by different viruses. Because these two types of illnesses have similar symptoms, it can be difficult to tell the difference between them based on symptoms alone. In general, influenza is worse than the common cold and symptoms such as fever, body aches, extreme tiredness and dry cough are more common and intense. Colds are usually milder than influenza. People with colds are more likely to have a runny or stuffy nose. Colds usually do not result in serious health problems such as pneumonia, bacterial infections or hospitalization.
