“…Conjunctivitis strongly indicated Zika virus infection (odds ratio [OR] 30.1, 95% CI 9.57–94.44; p < 0.001). In contrast, fever (OR 0.05, 95% CI 0.01–0.47; p = 0.008), myalgia (OR 0.20, 95% CI 0.08–0.48; p<0.001), and headache (OR 0.12, 95% CI 0.05–0.30; p<0.001) were more prominent in patients with DENV infection.
Further, DENV patients tended to have thrombocytopenia (median platelet count 132 × 109/µL, range 15–386 × 109/µL) and monocytosis (median monocyte count 0.50 × 109/µL, range 0.11–1.70 × 109/µL), whereas Zika patients tended to have normal platelet (median 225 × 109/µL, range 128–326 × 109/µL; p<0.001) and monocyte (median 0.35 × 109/µL, range 0.13–1.00 × 109/µL; p = 0.021) counts……”
