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?

Rationale: A. Syphilis is a nationally notifiable disease, meaning healthcare providers and laboratories are required to report confirmed cases to public health authorities. This allows for surveillance, outbreak tracking, and implementation of control measures to prevent further transmission. Syphilis is especially important to report because of its potential complications and association with congenital infection. B. HPV is very common and often asymptomatic. It is not nationally notifiable, largely because of its high prevalence and difficulty in tracking all cases. Public health reporting focuses on specific strains or related conditions (such as cervical cancer screening results in some contexts), but not routine HPV infection. C. Genital herpes (HSV) is not a nationally notifiable disease. Although it is a chronic sexually transmitted infection, routine reporting is not required because of its widespread prevalence and recurrent nature. D. Trichomoniasis is also not a nationally notifiable disease in most settings. While it is an STI that requires treatment, it is not routinely reported to public health authorities for surveillance purposes.
