Researchers from Great Britain have reported that Zika virus can be detected in semen for 62 days after initial infection. They were unable to grow live virus from these samples so it is not known whether men can transmit the infection to their sexual partners for that length of time. Zika, however, is known to be transmitted sexually. Until more is known, pregnant women and women desiring pregnancy should refrain from having unprotected intercourse (condom-free) with their partners who have contracted Zika for at least 2 months.
