Zika virus RNA presence in serum, whole-blood and urine samples from six Israeli travellers symptomatic for Zika virus disease was examined. Whole-blood samples were positive for as late as 2 months (58 days) post-symptom onset, longer than for urine (26 days) and serum (3 days). These findings suggest the utility of whole blood in Zika infection diagnosis.
