B42: Sporotrichosis
Sporotrichosis, coded as B42 in the ICD-10 WHO 2016 classification, is a fungal infection usually acquired from the environment. It is often associated with gardening or other outdoor activities that involve handling soil, moss, or plant materials that host the sporothrix fungus. People can also become infected through open skin wounds that come into contact with these substances. The disease typically progresses in a slow manner. Initial symptoms can include small, painless bumps (often pink or purplish) that appear on the skin where the fungus entered. Over time, these bumps can grow larger and may develop into open sores. The disease can also spread to other areas of the body, occasionally affecting the lungs, bones or joints, and even the nervous system in rare cases.
