Traces of Zika found in a man’s semen two months after he was infected Researchers are still unsure how long virus can linger in infected patients.
Two months after a 68-year old British man became sick with Zika virus, traces of the germ lingered in his semen, researchers reported Friday. The finding suggests that the mosquito-spread virus may unexpectedly hang around in the body for much longer than symptoms appear, which typically only last for about a week. (Though only a quarter or so of people infected with Zika experience any symptoms.) The viral loitering may up the chances of transmission, the authors speculate.
