Cutaneous larva migrans

Cutaneous larva migrans (CLM) is a skin infection caused by various parasites from the hookworm family (ancylostomatidae). These parasites are usually found in tropical and sub-tropical areas and live in animal hosts such as dogs, cats, and wild animals. It is most commonly contracted by coming into contact with the contaminated animal feces, usually on the ground. Though in animals this infection can spread into deeper tissues, in humans, the larva can only penetrate the upper layer of skin. Symptoms include very itchy red skin patches in the affected area that look like worm-like burrows. The skin patches may be painful and excessive scratching may cause secondary bacterial infections. CLM will usually go away on its own in a couple of weeks to months, but the process can be facilitated using certain topical or oral drugs. Anti-itch creams such as cortisone or Benadryl can help with symptom relief. To help prevent contracting this infection, wear shoes when walking in soil and beaches in tropical/sub-tropical areas. If you or a family member has contracted CLM, talk with your doctor about the most current treatment options.
