Travel-related congenital Zika infection associated with Asian lineage virus acquired in Thailand.

Congenital Zika infection is rarely reported in travellers to East Asia. We describe a case of a traveller infected during her ninth week of pregnancy in Thailand. Post-termination analysis revealed a significantly higher viral load in the fetal brain than in maternal blood, highlighting Zika's strong neurotropism and the Thai strain's ability to cause congenital infection.
