Vector competence parameters of Aedes albopictus and Aedes aegypti strains from Reunion Island infected with the African ZIKV strain Dak84 (infectious blood-meal viral titer of 106.85 PFU/ml). At 14 and 21 days after the infection, mosquitoes were examined for the presence of infectious viral particles detected by titration on Vero cells. The graphics ac correspond to infection rate (IR), dissemination efficiency (DE) and transmission efficiency (TE), respectively. The graphics df correspond to viral loads in bodies, heads and saliva, respectively. The numbers in parentheses indicate the number of positive samples (samples with infectious ZIKV particles). The error bars correspond to the 95% confidence interval. The asterisks indicate the level of significance of differences (NS: no significant difference; *P < 0.05; **P < 0.01; ***P < 0.001) obtained from Fisher’s exact tests (for infection rates, dissemination and transmission efficiencies) and Kruskal-Wallis tests (for viral loads in bodies, heads and saliva). Abbreviations: AG, Ae. aegypti; AL, Ae. albopictus; SM, Sainte-Marie; LR, La Rivière
