Rheumatic fever is a serious complication that can occur after an untreated or inadequately treated streptococcal throat infection. The risk of rheumatic fever increases especially in those who have had a previous episode.

Antibiotic prophylaxis is aimed at eradicating any leftover bacteria that might enter the bloodstream during dental or medical procedures, which could trigger an immune response leading to rheumatic fever. This preventive measure is crucial for individuals who have a history of rheumatic fever or certain heart conditions, as they are at heightened risk.

The other options, such as immediate surgery, long-term corticosteroid therapy, and a regular exercise regimen, do not directly address the bacterial infection or its prevention. Surgery may be necessary for other conditions related to heart damage caused by rheumatic fever, but it is not a prophylactic measure. Corticosteroids can help with inflammation but are not used as a preventive strategy in this context. Regular exercise, while beneficial for overall health, does not reduce the risk of developing rheumatic fever following a stre
