[Correspondence] Prospective Zika virus disease cohort: systematic screening
In December, 2015, the first imported case of Zika virus (ZIKV) infection was diagnosed in French Guiana in a group of 136 travellers returning from Suriname. No autochthonous cases had been detected in French Guiana at that time. To prevent secondary cases, we systematically screened co-travellers 1, 10, and 30 days after their return (clinical examination, urine samples, and blood samples). One case of ZIKV infection was confirmed when viral RNA was detected by real-time PCR (rtPCR) in blood or urine or when ZIKV IgM antibodies and neutralising antibodies were found in serum.
