B97.8: Other viral agents as the cause of diseases classified to other chapters

B97.8 refers to diseases caused by other viral agents. This category includes known viruses causing diseases that are classified under different chapters in the medical classification. These viruses can cause a wide range of symptoms and health issues in patients that can vary greatly based on the specific viral agent involved and the individual's health condition. They can be transmitted in multiple ways, such as through direct contact, airborne respiratory droplets, blood, or other body fluids, and even from mother to child during birth. Symptoms often mimic those of other illnesses and can range from mild to severe, such as fever, fatigue, and gastrointestinal issues. Viral diseases typically progress through stages, often starting with an incubation period before symptoms appear. They might affect multiple systems in the body. Although the specific disease progression and symptoms depend on the particular viral agent, the viral diseases in this category usually require comprehensive medical attention for diagnosis and management. This category excludes viruses causing specific diseases classified elsewhere.
