Abstract

We detected Zika virus RNA in rectal swab samples from 10 patients by using real-time reverse transcription PCR, and we isolated the virus from 1 patient. The longest interval from symptom onset to detection was 14 days. These findings are applicable to diagnosis and infection prevention recommendations.

Keywords: Brazil; Zika virus; infection; rectal swab; sexual transmission; virus persistence; viruses.

Detection of Zika virus RNA in human biological specimens from 8 patients, according to Ct and days after disease onset. Patient identification numbers above charts correspond to numbers in the Table. Horizontal dashed lines indicate real-time reverse transcription PCR cutoff Ct of 38. Disease onset is day 0 (screening visit), defined after interviewing patients about symptoms. Ct, cycle threshold.
