A new study finds that Zika's risk of sexual transmission appears to end in one month, quicker than health officials thought.
The study suggests health officials have been overly cautious in advising couples to abstain from sex or to use condoms for at least six months after a male partner comes down with Zika.
Officials at the U.S. Centers for Disease Control and Prevention said the results are spurring work on new and better recommendations. But they say the study itself is not enough to change current guidelines yet.
The study was published online Wednesday by the New England Journal of Medicine.
