How can you get infected with Ascaris? What hygiene measures need to be followed to prevent ascariasis?

Roundworms are parasitic annelids that live in humans and animals. For most of their life, adult roundworms live in the human intestine. During reproduction, ascaris eggs come out along with the feces and remain in the ground. In the air, ascaris eggs remain viable for a long time. You can get infected by eating unwashed berries or fruits, or through dirty hands. Ascaris eggs are very small, microscopic, and can even be accidentally inhaled through the nose or mouth.
