Group A Streptococcal Infections

Group A Streptococcus (Strep) bacteria can commonly be found in the nose and throat and on the skin, especially in children. It can cause "strep" throat, scarlet fever and skin infections. Sometimes it can cause more serious infections in otherwise healthy people.

It is spread by direct contact with secretions from the nose or throat of an infected person or by direct contact with secretions from infected sores on the skin. Children with chickenpox have a higher risk of developing skin infections from Group A Strep.

Group A Strep infections are treated with antibiotics. Once a person has been treated with antibiotics for twenty-four hours they are no longer infectious.
