Women with confirmed cases of the Zika virus or who have had symptoms of the virus should wait at least eight weeks after the start of their symptoms before trying to get pregnant, the U.S. Centers for Disease Control and Prevention said Friday.
Men with confirmed cases of the virus or who have had symptoms of the virus are now advised to wait at least six months after their symptoms begin before having unprotected sex.
These timelines update previous guidelines, based on new information learned about how long the virus stays in semen, Dr. Denise Jamieson of the CDC told reporters. They also address new concerns about when women become pregnant, whereas previous guidelines focused on women who were already pregnant.
