B95-B98: Bacterial, viral and other infectious agents

The B95-B98 group of conditions refers to infections caused by bacterial, viral, and other infectious agents. These infections can be transmitted in various ways, such as through direct contact, airborne droplets, ingestion of contaminated food or water, or bites from infected insects or animals. The onset of symptoms depends on the specific pathogen and the individual's immune response, but common signs may include fever, fatigue, muscle aches, and in some cases, cough, diarrhea, or skin rashes. These infections can affect multiple systems in the body, such as the respiratory, digestive, or integumentary system. Over time, without appropriate treatment, the severity of these conditions may increase, leading to complications or more chronic illnesses. The progression varies widely, based on the nature of the pathogen and the person's overall health status.
