Primary Prevention Fact Checked
Primary prevention of acute rheumatic fever (ARF) interrupts the link between group A streptococcal (Strep A) infections and the autoimmune response to the infection.1 If given early in the infection, antibiotics interrupt the autoimmune response and ARF does not occur.2,3 This requires identifying and treating Strep A infections of the throat and skin in people at high risk of ARF.
Some Australian population group are at high risk of ARF following Strep A infection, including:4
- Aboriginal and Torres Strait Islander peoples, particularly those living in rural or remote settings across central and northern Australia, are known to be at very high risk.
- Aboriginal and Torres Strait Islander peoples, and Māori and Pacific Islander groups living in urban settings, particularly where there is household crowding, are also at high risk.
- people with a history of ARF or rheumatic heart disease are at high risk of developing recurrent ARF.
Treatment for Strep A throat infections is either one intramuscular benzathine benzylpenicillin injection or a course of antibiotic tablets/syrup. Treatment for Strep A associated skin infection is either antibiotic tablets/syrup or one intramuscular benzathine benzylpenicillin injection.5
Antibiotics for Strep A throat infections in people at high risk of ARF can reduce development of ARF by up to two-thirds.6 However, Strep A is present in only between 10% and 40% of children presenting with a sore throat.7
Identifying the cause of the throat or skin infection is important to make sure the correct treatment is given. Waiting for test results for people (particularly children) at high risk for ARF may result in ARF developing before treatment is started. It is therefore recommended in Australia that all children in high-risk groups receive primary prevention with antibiotic therapy for sore throats and skin sores immediately after a swab has been taken. People who are not at high risk of ARF should generally not have primary prevention treatment started until a Strep A infection has been confirmed.8
