Longitudinal detection of ZIKV RNA in plasma, urine and oral swabs in subcutaneously infected animals (blue) or animals inoculated directly to the tonsils (orange). a Legend for graphs represented in parts b–d. Orange lines represent animals infected via the tonsils and blue lines represent animals infected via subcutaneous injection. b ZIKV RNA copies per ml of peripheral blood plasma. c ZIKV RNA copies per ml of passively collected urine from pans. d ZIKV RNA copies per oral swab. The gray box indicates the time frame in which saliva or an oral swab sample from saliva donor animals was used to challenge recipient animals. The y axis starts at the limit of quantification of the qRT-PCR assay (100 vRNA copies per ml)
