Correct answer: C — Fetal congenital infection risk

Fetal congenital infection risk is the single best answer because Zika infection in early pregnancy is associated with congenital Zika syndrome and needs obstetric and infectious disease input. Relapsing hypnozoite malaria 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 the illness is often mild in the mother, but fetal risk drives management.
