The Duke Criteria is a set of clinical guidelines used to diagnose infective endocarditis based on specific findings observed during patient assessment. The key to understanding the correct answer lies in the combination of major and minor criteria needed for a definitive diagnosis.

Infective endocarditis can be diagnosed using two approaches according to the Duke Criteria. The first approach indicates that having two major criteria is sufficient for a diagnosis. Alternatively, if only one major criterion is present, it can be accompanied by three minor criteria to meet the diagnostic threshold. This flexibility allows for the identification of infective endocarditis in patients who may not exhibit classic signs or symptoms but still demonstrate features that warrant a diagnosis when considered against the backdrop of clinical context.

Understanding the structure of the Duke Criteria is crucial for recognizing how various clinical presentations fit into the diagnostic framework for infective endocarditis. Having this knowledge empowers healthcare providers to assess patients accurately and ensure timely treatment.
