"World Health Organization Broadens Zika Sex Guidelines"

"The World Health Organization greatly broadened its recommendations about sexual transmission of Zika virus Tuesday, advising both men and women who have been in Zika-affected areas to practice safe sex for at least six months.

WHO says more and more studies are showing that sex may pass along Zika more often than anyone thought, and because of the risk to pregnancies it's better to be careful.

 And another study showed that Zika virus can be found in tears — at least in mice.

Zika is surprising researchers at every turn and WHO's decision is meant to protect pregnant women as much as possible. "
