Oregon health officials announced Thursday the state’s first confirmed case of the Zika virus.

Stressing that there is no danger to the public, Oregon Health Authority Public Health Division officials said a person in Oregon has been diagnosed with a travel-associated Zika virus infection.

Currently there is no further information about the victim. The adult woman — officials did not say where she lives — contracted the virus in an affected country outside the United States and has recovered.

It’s the first laboratory-confirmed case of Zika in Oregon this year. Before this case, three Oregonians have had travel-associated Zika confirmed since 2014.

Zika is spread by certain types of mosquitoes that bite an infected person, then bite an uninfected person. Sexual transmission of the disease also has been reported, though this appears to be rare, according to experts.

Zika symptoms, which include fever, rash, joint pain and redness of the eyes, are mild, and serious illness requiring hospitalization is uncommon.

The virus, however, may endanger pregnancies and so women who are pregnant or who may become pregnant should be particularly careful to avoid the disease and talk to their doctor, officials said.

Zika virus can be spread from a pregnant woman to her unborn baby and there have been reports of a serious birth defect of the brain called microcephaly in babies of mothers who had Zika virus while pregnant, the Centers for Disease Control and Prevention said.
