A recent study [1] reveals that patients with symptoms of Zika virus have detectable virus RNA [by RT-PCR] in the serum within two days of the onset of symptoms when urine samples remain negative.
However at four days after onset viral RNA is detectable in the urine at higher levels and [Asian lineage] RNA remains detectable in urine for longer: up to 14 days after onset of symptoms.
