Z20-Z29: Persons with potential health hazards related to communicable diseases

The ICD-10 category Z20-Z29 refers to a group of conditions associated with potential health hazards related to communicable diseases. These individuals may be carriers or have been suspected or confirmed to be in contact with infectious agents that could lead to disease. Communicable diseases can be transmitted from person to person or through vectors such as mosquitos, or by contact with an infected individual's bodily fluids. These conditions range widely, from respiratory diseases to sexually transmitted infections. Common symptoms that might occur can include fever, fatigue, cough, body aches, and potentially, localized pain or discomfort, depending on the specific disease. The progression of these conditions can vary, potentially involving any system in the body, and may result in mild, self-limiting illness or severe, life-threatening disease.
