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?

A. Impetigo: Impetigo is a common superficial skin infection and is typically not a nationally notifiable disease. Reporting is usually not required to the CDC unless part of a specific outbreak investigation. B. Pneumocystis pneumonia: This infection is often associated with immunocompromised individuals, such as those with HIV/AIDS, but it is not a reportable condition to the CDC under standard public health surveillance. C. Human papilloma virus: HPV infections are common and typically not reportable to the CDC for surveillance purposes, although certain high-risk HPV-related cancers are tracked indirectly. D. Hepatitis A: Hepatitis A is a nationally notifiable disease due to its potential for outbreaks and public health impact. Cases must be reported to local and state health departments, which in turn report to the CDC to monitor and control the spread of infection.
