Strep throat is an infection in the throat and tonsils (glands in the back of the throat) that is caused by a bacterium known as Group A streptococcus.

Strep throat can very rarely cause more serious illnesses, such as rheumatic fever, a disease that can harm the heart valves. So, it's important that strep throat is appropriately diagnosed and treated. With proper treatment, strep throat is usually cured within 10 days.

To prevent strep infection:

Wash your hands. Proper hand-washing is the best way to prevent all kinds of infections. That's why it's important to wash your own hands regularly with soap and water for at least 20 seconds. Teach your children how to wash their hands properly using soap and water or to use an alcohol-based hand sanitizer if there is no soap and water available.

Cover your mouth. Teach your children to cover their mouths with an elbow or tissue when they cough or sneeze.

Don't share personal items. Don't share drinking glasses or eating utensils. Wash dishes in hot, soapy water or in a dishwasher.
