A nurse manager in a community health clinic is reviewing the medical records of clients who have diagnoses of communicable diseases. Which of the following infectious diseases should the nurse report to the Centers for Disease Control and Prevention?

Choice A reason: Impetigo is a superficial bacterial skin infection, commonly caused by Staphylococcus aureus or Streptococcus pyogenes. While it is contagious, it is not a nationally notifiable disease that requires reporting to the CDC. Management is typically local, involving antibiotics and hygiene measures. Choice B reason: Pneumocystis pneumonia (PCP) is an opportunistic infection often associated with immunocompromised states such as HIV/AIDS. Although it is clinically significant, it is not a condition that requires mandatory reporting to the CDC. Instead, HIV infection itself is reportable, not PCP as an isolated diagnosis. Choice C reason: Human papillomavirus (HPV) is a common sexually transmitted infection. While HPV is widespread and associated with cervical and other cancers, it is not a nationally notifiable disease. Reporting is not required, though vaccination and screening programs are emphasized for prevention. Choice D reason: Hepatitis A is a viral infection transmitted via the fecal-oral route, often through contaminated food or water. It is a nationally notifiable disease because of its potential for outbreaks and public health implications. Reporting to the CDC is required to track cases, identify sources, and prevent further transmission. This makes it the correct answer.
