Colds & Influenza

The flu and the common cold are both respiratory illnesses. There are hundreds of different types of virus that can cause a cold, which is why children can get repeated colds, while the flu virus is constantly changing the structure, so new strains can appear each year. 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, the flu is worse than the common cold, and symptoms are more common and intense. Colds are usually milder than the flu. People with colds are more likely to have a runny or stuffy nose.
