In Am J Trop Med Hyg 74: 342–344 by Alonso et al, thereis an error in the fifth paragraph of the discussion on page343. The sentence reads "However, three years later a treatmentfailure with PZQ at a standard dose in a returning travelerwith S. haematobium infection was reported in whom a courseof 40 mg/kg for three consecutive days was finally curative."The sentence should have refered to a case of S. mansoni, notS. haematobium.
