First sexually-transmitted case of Zika reported in Pa.

HARRISBURG, Pa. (WPVI) -- The first sexually-transmitted case of Zika virus has been reported in Pennsylvania, according to the Department of Health.

"A Pennsylvania resident contracted the Zika virus from a mosquito while traveling outside of the state in an area where Zika transmission is occurring." said Secretary Karen Murphy. "Upon returning to the commonwealth, the person passed it via sexual transmission to their partner."

Officials urge residents to practice safe sex, "especially if they have traveled to an area with Zika-infected mosquitoes."

If you have traveled to an area where Zika virus is present, officials say condoms or other forms of protection should be used during sex for eight weeks upon return to prevent sexual transmission.

Women who are pregnant or planning to become pregnant are being urged to discuss their travel plans with their doctors if they include Zika-affected areas.

As of yet, no cases of Zika in Pennsylvania have occurred as a result of a local mosquito transmission.

Measures that people can take to prevent mosquito bites include:

-Applying an EPA-registered insect repellent to exposed skin and clothing;

-Wearing light-colored, lightweight, loose-fitting clothing that covers hands, arms, legs and other exposed skin;

-Staying and sleeping in air-conditioned or screened rooms or under a mosquito net when outdoors; and

-Staying indoors when mosquitoes are most active.
