Diagnosis of ectoparasite infestations typically involves a physical examination and identification of the parasite. For instance, the presence of nits (lice eggs) confirms a lice infestation, while a skin scraping may be necessary to diagnose scabies. Treatment usually involves the use of appropriate antiparasitic medications and may require multiple applications to ensure complete eradication. In some cases, antibiotics may be necessary to treat secondary bacterial infections.
