Federal health officials are warning women and men again that the Zika virus might be sexually transmitted and they should be taking precautions to avoid infection. The reminder comes as more potential cases of sexual transmission are being investigated.

FOX's Eben Brown reports:

The Centers for Disease Control say they, along with state health departments, are investigating 14 more cases of women becoming infected with Zika virus who may have acquired it from a sex partner.

Several of those 14 women are pregnant. In two of the cases, the only discernable risk factor was a male sex partner who traveled outside the U.S. to a location where local Zika transmission is rampant.

Health officials are reminding men and women to take precautions. Zika is highly believed to be the cause of thousands of babies born with skull and brain defects in Latin America.
