Maite Aubry et al. Emerg Infect Dis. 2017 Apr.

Abstract

During 2013-2014, French Polynesia experienced an outbreak of Zika virus infection. Serosurveys conducted at the end of the outbreak and 18 months later showed lower than expected disease prevalence rates (49%) and asymptomatic:symptomatic case ratios (1:1) in the general population but significantly different prevalence rates (66%) and asymptomatic:symptomatic ratios (1:2) in schoolchildren.

Keywords: French Polynesia; IgG; Zika; Zika virus; arbovirus; flavivirus; immunoglobulin G; seropositivity; seroprevalence; vector-borne infections; viruses; zoonoses.

Geographic distribution of participants recruited for a study of the postemergence seroprevalence of Zika virus infections in French Polynesia, 2014–2015. N1 and N2 indicate areas of recruitment among the general population during February and March 2014 and September–November 2015, respectively; N3 indicates areas of recruitment among schoolchildren during May and June 2014. The total population and number of recruited participants is shown for each area. Lines delineate the 5 archipelagos that comprise French Polynesia (Marquesas, Society, Tuamotu, Gambier, and Australs). Inset map at upper left shows location of French Polynesia in the Pacific Ocean (white circle).
