Correct answer: A — Praziquantel treatment with follow-up for persistent eggs or urinary morbidity

The best answer is “Praziquantel treatment with follow-up for persistent eggs or urinary morbidity”. Terminal-spined urinary eggs identify S. haematobium. Praziquantel is the treatment of choice, with follow-up because immature worms at earlier treatment, reinfection or heavy disease can leave persistent egg excretion and urinary-tract morbidity. Other listed antiparasitic agents do not treat adult schistosomes.
