Larva currens
Other names: Nutria itch[1]

Larva currens (Latin for racing larva), is an itchy skin condition caused by infections with Strongyloides stercoralis.[2][3]

It is caused by the intradermal migration of strongyloides and distinguished from cutaneous larva migrans (caused by hookworm) by its rapid migration, perianal involvement and wide band of urticaria.[4]
