(Olympia, WA) -- State health officials say the first case of Zika virus in Washington has been confirmed. The state Department of Health says the patient is a man in his 20s who recently traveled to the South Pacific, where the virus has been spreading. He's being treated at a Thurston County hospital. Officials say it's unlikely Zika will spread in Washington, as the virus is transmitted through the bite of a type of mosquito that isn't found in the state.
