B88: Other infestations

The group of conditions classified under "Other Infestations" involves various types of infections or diseases caused predominantly by parasites. The parasites can be tiny insects, mites, ticks, or microscopic organisms that live on or in the human body. They usually spread through direct contact, bites from the bugs, or indirect transmission, such as contaminated water, soil, or food. Common symptoms can include skin rashes, itchiness, red marks, or bumps and, in some cases, systemic symptoms like fever, fatigue, or abdominal pain, depending on the species of the parasite and the area of infestation. The progression of diseases in this group is quite variable as it significantly depends on the type of parasitic infestation, but without treatment, most of these conditions tend to worsen and spread. These infestations generally affect the integumentary (skin) system, but can also impact the digestive, nervous, and circulatory systems if the parasites migrate or reproduce within the host's body.
