A northwest Oregon resident has tested positive for coronavirus with no known history of travel to countries severely affected by the outbreak and no known contact with infected individuals, state health officials said Friday.
The case, in Washington County, marks the third case of unknown origin in the United States and indicates that the virus is spreading. It is also the first coronavirus case in Oregon.
The case, which was diagnosed through one of the Centers for Disease Control and Prevention’s testing kits, was found in an individual who works as a school employee in Clackamas County, who “may have exposed students and staff there,” according to the Washington County Department of Health and Human Services.
The sample will be sent to CDC’s Atlanta headquarters for confirmation.
