New Zika Virus Guidelines Focus on Safe Sex

The World Health Organization (WHO) is issuing new safe sex guidelines for people traveling abroad to areas where Zika has been identified. The guideline advises that people returning from areas where the Zika virus is found should follow safe sex practices or abstain from sex for at least eight weeks rather than just four. This recommendation, which doubles the abstinence period the WHO previously had advised, comes after scientists found the virus lingers longer than previously thought in blood or other body fluids.
