B94: Sequelae of other and unspecified infectious and parasitic diseases

Sequelae of other and unspecified infectious and parasitic diseases refer to the long-term effects or complications that occur as a result of an infectious or parasitic disease that has been previously treated or cured. These complications or effects may persist, not because the infection or parasite is still present, but due to the damage they may have caused to the body during the episode of illness. The diseases are initially transmitted by various means including consumption of contaminated food or water, direct contact with an infected person or animal, or through insect and vector bites. Common symptoms during the initial illness could include fever, fatigue, muscle aches, and localized pain, while the lasting effects can vary greatly depending on the type and severity of the infection, and the body systems affected. These may include neurological disorders, chronic pain, organ malfunction, and physical deformities.
