The best defense against ascariasis is good hygiene and common sense. Follow these tips to avoid infection:
- Practice good hygiene. Ascariasis is spread by ingesting parasite eggs from contaminated soil. Before handling food, always wash your hands with soap and water, and wash fresh fruits and vegetables thoroughly.
- Use care when traveling. Ascariasis is the most common roundworm infection in the world, with higher infection rates in developing and warm-climate countries. When traveling, use only bottled water and avoid raw vegetables unless you can peel and wash them yourself. As a rule, eat only foods that are hot and cooked.
