Mild infections may not cause symptoms.

More serious infections may cause the following symptoms:

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

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.
