Which of the following conditions is necessary to report to the proper authorities?

Cirrhosis is a chronic liver disease resulting from various conditions, such as alcohol abuse or hepatitis. While it is a serious medical condition, it is not classified as a communicable disease and does not require reporting to health authorities in the same manner as infectious diseases.

Emphysema is a progressive lung disease primarily caused by smoking and is part of chronic obstructive pulmonary disease (COPD). Similar to cirrhosis, emphysema is not an infectious disease and does not need to be reported to authorities, focusing instead on individual patient management.

Herpes zoster, also known as shingles, results from the reactivation of the varicella-zoster virus. While it can cause significant discomfort and complications, it does not require mandatory reporting as it is not classified as a communicable disease in the same way as gonorrhea.

Phlebitis refers to the inflammation of a vein and is usually caused by factors such as injury or blood clots. Phlebitis is not an infectious disease and does not involve public health reporting requirements, as it is typically a localized condition rather than a widespread health threat.
