Benign in most people, Zika has been linked to microcephaly - a shrinking of the brain and skull - in babies, and to rare, potentially-fatal adult-onset neurological problems.
In an outbreak that started in 2015, about 1.5 million people have been infected with Zika in Brazil, and more than 1,600 babies born with microcephaly, suggested the World Health Organization.
‘The Zika virus has been found alive in a man's sperm after a record 93 days, revealed a new report that adds to the many unknowns surrounding the fetus-harming germ.’
AdvertisementZika is transmitted mainly though the bites of infected mosquitoes, in rare cases via sex, but also through the placenta to unborn children. The previous longest recorded Zika virus survival in semen was 62 days after the onset of symptoms.
The Zika virus has been found alive in a man's sperm after a record 93 days, revealed a new report that adds to the many unknowns surrounding the fetus-harming germ.
The 27-year-old Frenchman's semen tested positive for Zika in March 2016, three months after he experienced symptoms of an infection picked up while traveling in Thailand in October and November, 2015.
The case was reported in The Lancet medical journal this week.
The new case highlights that people returning from areas where Zika is non-endemic, such as Thailand, can also be infected, said the report authored by health specialists from Toulouse in southern France.
The possibility of "protracted" virus presence should be kept in mind when people plan to have children, it added.
"The existing six-month period for monitoring virus survival in infected people should be expanded to patients returning from non-epidemic areas," wrote the team.
