2 Zika cases in Pennsylvania, 1 in Delaware

State health authorities say two female Pennsylvania residents have tested positive for the Zika virus.

The Pennsylvania Department of Health said Tuesday the two had recently traveled to countries affected by the ongoing outbreak of the mosquito-borne virus.

Delaware officials also reported that state’s first case of the virus, also travel related. Pregnancy is not an issue for the woman in Delaware, officials said. No further details were released about the two Pennsylvania residents.

Pennsylvania Secretary of Health Dr. Karen Murphy said officials are concerned about the health of those individuals and others who may be exposed, but they want to emphasize the cases “pose no threat to the public.”

Medical authorities say most people recover in about a week from symptoms that include fever, a rash and achy joints, but doctors believe the virus puts pregnant women at serious risks for birth defects.
