These hardly need mentioning, as most people have experienced them. The symptoms include a runny nose, coughing, sore throat, sneezing, and fever. Although these symptoms can be quite debilitating, the disease is regarded as relatively mild in most cases. Fevers are usually low or even absent and the disease normally resolves within seven to ten days. Some colds can have a persistent cough that continues even for weeks after the other symptoms have cleared.
Occasionally the common cold can progress to more serious illnesses like pneumonia or secondary bacterial infections of the respiratory tract or ear infections. The common cold can aggravate asthmatic conditions.
