Fig. 2: Viral RNA levels in plasma and tissues.

a Plasma vRNA levels during acute infection during the first 40 days in naïve controls expressed as International Units (IU) /mL. b Cell-associated ZIKV RNA levels in tissues, expressed as International Units (IU) per µg total RNA in peripheral lymph nodes (PLN), both inguinal (ILN) and brachial (BLN), spleen, mesenteric (MLN), salivary gland and genital lymph nodes (LN). Macaque R5 was terminated 5 weeks p.i, R11, R12 at 10 weeks p.i. and R13 at 6 weeks p.i. c and d indicate plasma vRNA and tissue cell-associated RNA levels respectively in immunised macaques (R1–R4).
