France reported a total of 11 travel associated ZIKV cases linked to Indonesia between July 2025 and March 2026, including four cases detected in early 2026. Most cases were associated with travel to Bali and neighboring islands. All cases were laboratory confirmed, and Asian lineage was identified in sequenced samples.
Despite high and increasing travel volumes from Indonesia to the EU/EEA since 2022, no corresponding increase in imported ZIKV cases has been observed by other EU/EEA countries.
Zika is endemic in Indonesia. CDC does not classify Indonesia as an area with a current Zika outbreak (for outbreaks, see CDC Zika Travel Health Notices).
Prevention:
- Optimal mosquito bite protection 24/7, also in cities (during the day against dengue, chikungunya, Zika and other viruses, at dusk and at night against malaria).
- Travellers, especially pregnant women or women who plan to become pregnant, should be aware of the ongoing Zika risk in Indonesia and that Zika virus infection. Pregnancy (at any trimester) can cause fetal malformation as it is the case for other infections during pregnancy. For detailed ECTM recommendations on Zika, see LINK.
In case of fever, seek medical care. This is also important to rule out malaria which is endemic in Indonesia.
