ATLANTA — U.S. and international health officials are easing warnings against travel to regions with Zika virus because the threat has diminished markedly since the virus began to sweep across the globe four years ago.
The World Health Organization designated Zika a global health emergency in 2016, and the Centers for Disease Control and Prevention told women who were pregnant or might become pregnant to stay away from nearly 100 countries or regions. The mosquito-borne virus can cause severe birth defects.
Last month, the CDC downgraded its warning; a spokeswoman said the WHO will soon follow with similar, less-restrictive travel recommendations. Officials said the disease has died down in most of the world — although they think it is still circulating at a much lower level.
