The adult parasite thrives in the blood of infected poultry or mammals, especially those that live in or near water such as ducks and swans. The adult parasites that produce eggs are then passed in the feces of infected poultry or mammals. The eggs then hatch into microscopic larvae, looking for specific aquatic snail species to infect.
Once infected with snails, they will live off the host's blood before maturing into adults. They then produce another type of microscopic larvae that will cause atopic dermatitis.
Usually, when infected snails release larvae into the water, they swim in search of a bird or aquatic mammal. In general, humans are not perfect hosts for the parasites, but they can still burrow into the skin, causing allergic reactions and itchy rashes. Since the larvae cannot survive in the human body, they will eventually die on the skin.
