[1] Symptoms increase with the number of worms present and may include shortness of breath and fever in the beginning of the disease. [1]

Nematodes causing such zoonotic infections are Baylisascaris procyonis, [2] Toxocara canis, [3] Toxocara cati, [3] and Ascaris suum. [4] These nematodes can infect but not mature in humans and after migrating through the intestinal wall, travel with the blood stream to various organs where they cause inflammation and damage.
