Prevention of RHD can be classified into three levels: - Primary prevention: Involves early diagnosis and treatment of streptococcal throat infections with antibiotics to prevent the initial occurrence of rheumatic fever. - Secondary prevention: Focuses on preventing recurrent rheumatic fever episodes in individuals with a history of the disease through long-term antibiotic prophylaxis. - Tertiary prevention: Aims to manage and reduce complications in patients with established RHD through medical and surgical interventions.
