Strep A Advice

Group A Streptococcus is the name given to a type of bacteria sometimes found in the throat or on the skin. Group A Streptococcus usually causes mild illness like sore throats and skin infections. Rarely these bacteria can cause severe and life threatening illness called invasive Group A Streptococcal disease.

Many people carry Group A Strep harmlessly and do not develop illness. It can be passed from person to person by close contact such as kissing or skin contact. Most people who come into contact with Group A Strep remain well and symptom free, some get mild throat or skin infections. Contracting invasive disease from a relative or household member is very rare. You can reduce the risk of picking up Group A Strep by always washing your hands thoroughly. Pregnant women or those having gynaecology treatments are advised to wash their hands before and after going to the toilet. It is also important to dispose of tissues after use and to wash your hands when you have a cough or cold.

Group A Strep can cause throat infection, scarlet fever or skin infections such as cellulitis or impetigo. These infections are usually treated with antibiotics. Very rarely it can cause severe illness when the bacteria get into parts of the body that are usually free from bacteria such as the lungs, blood or muscles. This is called invasive Group A Streptococcal disease. Invasive disease happens when the bacteria get past your body’s immune defences. This can happen when you are already ill or are on treatments, such as some cancer treatments, that affect your immune system. Two of the most severe types of invasive disease are necrotising fasciitis and toxic shock syndrome.
