Distinguish primary from secondary prevention of ARF and give an example of each from the lecture.
Answer
Primary prevention prevents a first ARF attack by identifying and treating GAS pharyngitis promptly, ideally before the ninth day of symptoms. Secondary prevention prevents recurrent GAS infection and ARF in someone with prior ARF by continuous antibiotic prophylaxis, such as intramuscular benzathine penicillin G every four weeks.
Explanation
The distinction is whether ARF has already occurred. Treating pharyngitis prevents the first attack; ongoing prophylaxis reduces recurrence risk in patients with ARF history. **Key takeaway:** Prevention strategy depends on whether the goal is a first attack or recurrence prevention. **Glossary:** Benzathine penicillin: a long-acting intramuscular penicillin preparation.
