State officials have confirmed two more cases of the Zika virus in Delaware.
These two patients bring the total number of cases to three.
Officials say none of the people were infected in the United States.
They all got the virus from a mosquito bite while traveling abroad.
An adult male was tested after showing symptoms of the disease from a January 2016 trip.
An adult female also showed symptoms of the disease following a late February-early March trip.
The first case involved a woman, as well.
Neither women were pregnant.
There is no vaccine for Zika, which can cause birth defects.
The Centers for Disease control is urging all pregnant women to postpone travel to South America, where the virus is most prevalent.
