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

Z25: Need for immunization against other single viral diseases

This group of conditions pertains to viral diseases for which immunization is required. These are typically diseases caused by specific, unique viruses. The transmission method depends on the virus involved but can include direct contact, airborne particles, or the exchange of bodily fluids. Common symptoms also vary widely depending on the disease, but might include fever, rash, cough, fatigue, or other systemic symptoms. Over time, these diseases can progress and possibly cause more serious health complications, depending upon the specific viral disease. The body systems affected by these conditions can be different based on the viral disease; some may primarily affect the respiratory system, others the digestive system or even the nervous system. Vaccination against these diseases plays a crucial role in preventing the onset of the diseases and reducing the risk of complications.
