Question

Quizplus · Accepted Answer

Many parasites, such as worms and protozoans, release fertilized eggs in the faeces of humans and other animals. Without toilets, these eggs can contaminate soil and water sources, leading to the spread of diseases such as cholera, typhoid fever, and hookworm infection. Toilets help to properly dispose of human waste and prevent the spread of such diseases. The other options (A, B, and C) are incorrect because toilets do not necessarily disinfect or kill disease-causing insects.
