Less than half of Americans know this about Zika. Do you?

Less than half of American adults know that the Zika virus can be sexually transmitted.

That’s according to a new survey released by The National Campaign to Prevent Teen and Unplanned Pregnancy.

“With the Zika virus emerging as a critical public health issue here and around the globe, it is even more important for us to be intentional about when, if, and under what circumstances to get pregnant,” said Ginny Ehrlich, CEO of the nonprofit.

Only 49 percent of respondents said they knew Zika could be sexually transmitted – and 64 percent said they knew “little or nothing” about the virus.

The nonprofit commissioned the survey, and it was carried out through telephone interviews by SSRS, an independent research company. The sample included 1,009 responded between the ages of 18 and 45.

South Carolina confirmed its first case of Zika in April.
