The common cold is a contagious viral infection of the upper-respiratory tract. This includes the nose, throat, and sinuses. A cold also affects the ears and lungs. Colds are the most common disease in the world. Colds affect all ages (often infants and children) and may occur 2 to 10 times in a year in an individual.

• There is no cure for a cold. Self-care and time are usually all that is needed for a cold. There are manyremedies for cold symptoms. They include nonprescription cold preparations, getting extra rest, drinking plenty of fluids, and others that may be suggested by friends and family members. One or more of these may help you feel better until the body’s defenses fight off the germs. •Don’t smoke. It can further irritate the nasal passages. • For a baby too young to blow his or her nose, use an infant nasal aspirator. Don’t insert cotton swabs into a child’s nostrils.
No drugs, including antibiotics, can cure the common cold. To help relieve symptoms, adults may use nonprescription drugs, such as acetaminophen, decongestants, nose drops or sprays, cough remedies, and throat lozenges. It is best to get a product that works for one symptom, such as a runny nose, rather than a multisymptom product. If you take other drugs, talk to your health care provider or pharmacist about possible drug interactions. For colds in children, don’t use any nonprescription product unless advised by a health care provider or the label states that it can be used for your child’s age.
Bed rest is not needed. Do reduce activity and exercise.
