Correct answer: D — Avoid freshwater swimming and wading

Avoid freshwater swimming and wading is the single best answer because schistosomiasis is acquired through cercarial penetration during freshwater contact. Take weekly chloroquine is plausible in a related presentation, but it is less appropriate because it does not fit the key discriminator in this vignette. The teaching point is that there is no vaccine, so exposure avoidance and post-travel testing where appropriate are key.
