CDC probing 14 new reports of Zika sexual transmission
The U.S. Centers for Disease Control and Prevention said on Tuesday it was investigating 14 new reports of possible sexual transmission of the mosquito-borne Zika virus, including several involving pregnant women.
In two of the suspected cases, the infection has been confirmed in women whose only known risk factor was sexual contact with an ill male partner who had recently traveled to an area where the virus is present, the agency said.

Testing of the male partners is still pending, the CDC said.
Mosquito bites remain the primary way the virus is spread, although sexual transmission is possible, the agency added.
The new cases, like the previously reported ones, involve possible transmission of the virus from men to their sex partners.
At this time, there is no evidence that women can transmit Zika virus to their sex partners, CDC said.
CDC also issued a Health Advisory Notice on Tuesday, as the new reports suggest sexual transmission may be a more likely means of transmission for Zika than previously considered.
The agency in early February revised its guidelines for pregnant women to include a recommendation that even those without symptoms of the Zika virus should be tested after returning from affected areas.
