WHO urges precautions in Zika areas but reassures most births normal

GENEVA (Reuters) - The World Health Organization on Wednesday advised women in areas with the Zika virus, especially during pregnancy, to cover up against mosquitoes and practice safe sex but also reassured them that most would give birth to "normal infants".

Acknowledging "understandable concerns" due to the risk of babies with birth defects, the WHO issued recommendations but conceded that "many unknowns" still surround the virus sweeping across the Americas.
