Survey: Americans uninformed on Zika risks

Most Americans who have been exposed to some information about the Zika virus are aware of its links to birth defects, but misinformation persists about testing and vaccination for it, according to a new survey. Four in 10 Americans have heard little to nothing about the virus, according to the Associated Press-NORC Center for Public Affairs Research survey. Meanwhile, 90 percent of respondents who were aware of the virus knew it could be transmitted through mosquito bites, but only 57 percent were aware it could also spread through sexual intercourse.
