Larva currens
Larva currens
Larva currens (/ˈlɑːrvə ˈkʌrɛnz/), also known as creeping eruption or cutaneous larva migrans, is a skin condition caused by the migration of parasitic larvae, particularly those of the Strongyloides stercoralis species.
Etymology
The term "larva currens" is derived from Latin, with "larva" meaning "ghost" or "mask", and "currens" meaning "running". This refers to the rapid movement of the larvae under the skin, which can be observed as a moving, raised red line.
Symptoms
The primary symptom of larva currens is an intensely itchy, red, raised rash that moves rapidly across the skin. This is due to the fast movement of the larvae, which can travel up to 10cm per hour. Other symptoms may include abdominal pain, diarrhea, and cough if the larvae have migrated to the lungs.
Diagnosis
Diagnosis of larva currens is primarily based on the characteristic appearance of the rash and a history of exposure to contaminated soil or feces. Laboratory tests, such as a stool sample or skin biopsy, may be used to confirm the diagnosis.
Treatment
Treatment for larva currens typically involves antiparasitic medications, such as Ivermectin or Albendazole. Topical corticosteroids may also be used to relieve itching.
Prevention
Prevention of larva currens involves avoiding contact with contaminated soil or feces, particularly in areas where Strongyloides stercoralis is common. This includes wearing protective clothing and shoes, and practicing good hygiene.
