Skin infestations occur when parasites, such as lice, scabies mites, or fleas, invade the skin. These tiny organisms can cause irritation, itching, and inflammation as they feed on skin cells or blood. Infestations can happen in various environments, often spreading through close contact or shared items like clothing and bedding. Treatment for skin infestations typically involves topical or oral medications that target the specific parasite. Maintaining good hygiene and cleaning living spaces can help prevent the spread of infestations. It's essential to consult a healthcare professional for proper diagnosis and treatment options.
