What are the symptoms of parasitic skin infections?

The symptoms of parasitic skin infections usually include itchiness and blisters or bumps on the skin. Some infestations cause red marks on the skin that look like threads. Parasite infestations can affect skin on almost any part of the body and depends on where the parasite or infected person, item of clothing, towel, or bedding touches the body. Some cutaneous, or skin-related, types of parasitic infections, like lice, infest specific parts of the body such as the hair and scalp or pubic area.
