A charge nurse is teaching a newly licensed nurse about nationally notifiable diseases. Which of the following diseases should the charge nurse include in the teaching as being reportable?

A. Syphilis: Syphilis is a nationally notifiable disease in the United States. Healthcare providers are required to report cases to local or state public health authorities to facilitate disease tracking, outbreak management, and public health interventions. B. Trichomoniasis: Trichomoniasis is not a nationally notifiable disease. While it is a common sexually transmitted infection, reporting is not required by law at the national level, though some states may have local reporting requirements. C. Genital herpes: Genital herpes is not nationally reportable because it is highly prevalent and often managed in outpatient settings without mandatory reporting. Surveillance focuses on population studies rather than individual case reporting. D. Human papillomavirus (HPV): HPV infections are not nationally notifiable. Although HPV is common and associated with cancers, individual cases are not reported to public health authorities. Reporting is limited to cancer registries for HPV-related malignancies.
