This is the first laboratory-confirmed case of Zika in Oregon in 2016. Before this, 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. Zika symptoms, which include fever, rash, joint pain and redness of the eyes, are mild, and serious illness requiring hospitalization is uncommon. However, Zika may endanger pregnancies, so women who are pregnant or who may become pregnant should be particularly careful to avoid the disease.

“We have been informing physicians whom to test for Zika and sharing information on how travelers can protect themselves from being bitten by mosquitoes,” says Richard Leman, MD, an OHA public health physician. “We want to help Oregonians protect themselves.”

The Oregon Health Authority is in regular contact with health officials at the Centers for Disease Control and Prevention, which is partnering with the World Health Organization and other global health organizations to ensure the latest and most up-to-date information about the Zika outbreak is available to health agencies around the world.
