Zika Virus Will Spread Across Americas, Warns World Health Organization

The World Health Organization said Monday that the Zika virus, which is linked to brain deformities in fetuses, will spread to all but two countries in the Americas. In Brazil, nearly 4,000 suspected cases have been reported since October, compared with fewer than 150 cases in all of 2014. The WHO statement comes after El Salvador, Jamaica and Honduras advised women to delay pregnancies.
