First case of laboratory-confirmed Zika virus infection imported into Europe, November 2013

Abstract

In November 2013, an acute Zika virus (ZIKV) infection was diagnosed in a German traveller returning from Thailand. The patient reported a clinical picture resembling dengue fever. Serological investigations revealed anti-ZIKV-IgM and -IgG, as well as ZIKV-specific neutralising antibodies in the patient’s blood. In Europe, viraemic travellers may become a source of local transmission of ZIKV, because Aedes albopictus (Skuse) and Ae. aegypti (Linnaeus) are invasive mosquitoes and competent vectors for ZIKV.
