Streptococcal infections (Group A)

Group A streptococcus (GAS) are bacteria found in the throat and on the skin. These bacteria can cause many different infections ranging from minor illnesses to very serious and deadly diseases, including strep throat, scarlet fever, impetigo, and others. Occasionally, the bacteria can be more severe and can begin to destroy the skin (known as necrotizing fasciitis). GAS is spread by direct contact with an infected individual or secretions from the throat or nose of an infected person.
