A nurse in the infectious disease division of the local health department is caring for a client. Which of the following infections should the nurse identify should be reported to the health department?

A. Clostridium difficile: C. difficile infections are typically managed within healthcare facilities and are not considered reportable to local health departments under standard public health reporting requirements. B. Herpes simplex virus: HSV infections are common and usually not reportable to public health authorities, except in cases of neonatal herpes or unusual outbreaks, as routine cases are managed clinically. C. Chlamydia trachomatis: Chlamydia is a sexually transmitted infection that is nationally notifiable. Reporting to the local health department is required to track incidence, prevent spread, and facilitate partner notification and treatment. D. Human papilloma virus: HPV infections are widespread and typically not reportable because most cases are asymptomatic or self-limiting. Reporting is not required for routine surveillance or treatment purposes.
