B95-B98: Bacterial, viral and other infectious agents

B98: Other specified infectious agents as the cause of diseases classified to other chapters

The classification B98 in ICD-10 represents a group of infectious diseases caused by specified infectious agents that are typically not classified within other disease categories. These conditions can result from various types of microorganisms such as bacteria, viruses, fungi, or parasites that have the ability to invade and multiply within the human body. Transmission of these infectious agents can happen in countless ways, including person-to-person contact, airborne transmission, contact with contaminated surfaces, or through vectors like insects. The common symptoms associated with these conditions can be quite diverse due to the varied nature of the diseases in this group, however, they often involve fever, fatigue, body aches, and in some cases, more specific signs relating to the system of the body affected. The progression of these diseases also varies greatly, based on both the specific infectious agent involved and the individual patient's immune response. Each of these conditions can potentially affect any system in the body, highlighting their complex and wide-ranging impacts on overall health.
