Toxocara infection is brought on by parasitic roundworms that mostly affect animals. The infection is caused by roundworm larvae that are typically present in the intestines of dogs and cats. A Toxocara parasite (T. canis) can be passed to puppies through the mother’s milk or during pregnancy. Then, the worm eggs are shed by the animals in their feces. You can contract the infection if feces, dirt, or sand that has been in contact with the eggs gets into your mouth.
Anyone can get toxocara infection, although young children and pet owners are especially susceptible. Children who play in and consume dirt with pet droppings experience the most severe instances.
