Question

Quizplus · Accepted Answer

Blood flukes require freshwater snails as an intermediate host to complete their life cycle. Therefore, reducing the population of freshwater snails would interrupt the life cycle of blood flukes and reduce their incidence in the human population. Other options such as reducing the mosquito population or purifying all drinking water would not directly affect the blood fluke life cycle. Avoiding contact with rodent droppings and washing raw fruits and vegetables can prevent other types of infections but would not specifically target blood flukes.
