Association of qualitative viral load data with detectable levels of Zika virus (ZIKV) NS3 antigen. A, The percentage of patients with detectable ZIKV RNA in urine or serum samples. ***P < .001 by a 2-tailed Fisher exact test. B, The percentage of patients from both acute and early convalescent phases with measurable levels of ZIKV RNA in urine samples. All urine and serum samples were obtained during the patients’ first visit to the clinic. C, The percentages of patients with or without fever during admission. D, Segregation of ZIKV antigen detection during the acute and early convalescent phases among patients with or without fever. *P < .05 and ***P < .001, by a 2-tailed χ² test.
