What is the most appropriate treatment in the following case?

Praziquantel-this girl has schistosomiasis, for which praziquantel is the recommended treatment. there are several species of this trematode which can infest humans, found in africa, south america, the caribbean, the middle east, and asia. transmission occurs when the schistosomal larvae (cercariae) are released by certain freshwater snails which they also infest. they burrow into the skin, often on the soles of the feet, and spread via the venous circulation to the lungs, from where they then pass into the systemic circulation. they are carried to the portal circulation where they mature, and progress to chronically infest the venous plexuses of either the bowel (s. japonicum, s. mansoni) or the bladder (s. haematobium). the eggs they release then migrate and are passed in the stools or urine, causing an intense granulomatous reaction. this can lead to ulceration or obstruction. ectopic deposition leads to symptoms affecting other organs. infestation is often asymptomatic, but may lead to presentation months or years. katayama fever is an acute serum-sickness like reaction seen several weeks following infestation.
