High specificity of a novel Zika virus ELISA in European patients after exposure to different flaviviruses
MetadataShow full item record
The current Zika virus (ZIKV) epidemic in the Americas caused an increase in diagnostic requests in European countries. Here we demonstrate high specificity of the Euroimmun anti-ZIKV IgG and IgM ELISA tests using putative cross-reacting sera of European patients with antibodies against tick-borne encephalitis virus, dengue virus, yellow fever virus and hepatitis C virus. This test may aid in counselling European travellers returning from regions where ZIKV is endemic.
