Which one of the following sexually transmitted diseases (STDs) is NOT required to be reported to the Centers for Disease Control and Prevention (CDC)?

Rationale: A. Syphilis is a nationally notifiable STD and must be reported to the CDC to track infection rates and facilitate public health interventions. B. Gonorrhea is also a reportable STD to the CDC for surveillance and prevention purposes. C. Hepatitis B, when sexually transmitted, is reportable to the CDC as part of infectious disease monitoring. D. Human papillomavirus (HPV) is not a reportable STD in most jurisdictions because it is highly prevalent, often asymptomatic, and routine reporting is not practical or required for public health tracking.
