WHO Issues New Safe-Sex Guidelines for Zika

GENEVA — 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, the World Health Organization said Tuesday.

The 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, spokesman Christian Lindmeier told a news briefing.
