Visceral larva migrans

  • Alternative Names

    Toxocariasis; Ocular larva migrans; Larva migrans visceralis


    Mild infections may not cause symptoms.

    More serious infections may cause the following symptoms:

    • Abdominal pain
    • Cough
    • Fever
    • Irritability
    • Itchy skin (hives)
    • Shortness of breath
    • Wheezing

    If the eyes are infected (called ocular larva migrans), loss of vision and crossed eyes (strabismus) may occur.

    Signs and tests

    If you have visceral larva migrans, you may have a higher-than-normal level of white blood cells.

    People with this condition may also have signs of a swollen liver, rash, and lung or eye problems.

    Tests may include:

    • Complete blood count with differential
    • Blood tests to detect antibodies to Toxocara
