Streptococcal infections (Group A)
Streptococcal infections (Group A)
Group A streptococcus (GAS) are bacteria that often live in the nose, throat, and on the skin. These bacteria can cause many different infections ranging from minor illnesses such as strep throat, scarlet fever, and impetigo, to major illnesses such as cellulitis and streptococcal toxic shock syndrome. Occasionally, the bacteria can be more severe and deadly and can begin to destroy the skin (known as necrotizing fasciitis) or cause streptococcal toxic shock syndrome. GAS bacteria are very contagious and spread by direct contact with an infected individual or secretions from the throat or nose of an infected person (usually mucus or droplets created when someone talks, coughs, or sneezes). There is no vaccine for group A streptococcus infections. The best way to prevent streptococcus infections is to wash your hands properly and regularly and avoid touching your face with unwashed hands.
