Which of the following helps in preventing ascariasis?

Ascariasis is a disease caused by a roundworm. The mode of transmission of this disease is through unwashed raw vegetables which contain the eggs of the worm. Proper washing and cooking of the vegetables before consumption prevents ascariasis. Soil is also a source of the worms. Children often become infected when they put hands in their mouths after playing in contaminated soil. So, it is also important to teach them to wash their hands after playing with soil.
