Question

Quizplus · Accepted Answer

Schistosoma species require water snails as intermediate hosts to complete their life cycle. Proper sewage and water treatment would eliminate infected waste and reduce the number of snails in the water, which would in turn reduce the prevalence of infection. Elimination of stagnate water would also help but may not be as comprehensive as proper sewage and water treatment. Bed nets and frequent sanitization of shared toilets, showers, and saunas would not be effective since the infection is acquired through contact with contaminated water, not through direct contact with infected individuals.
