Since the start of 2019, the EuroTravNet/GeoSentinel and TropNet data collection networks for the surveillance of travel-related morbidity have identified nine patients with chikungunya virus (CHIKV) infection imported from Thailand to Sweden, Switzerland, the United Kingdom (UK), Romania, Israel and France.
