Mild infections may not cause symptoms.
More serious infections may cause the following symptoms:
If the eyes are infected, loss of vision and crossed eyes (strabismus) may occur.
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.
A blood test can be done to detect and diagnose the infection.
