Snohomish County health officials probe positive blood tests

SEATTLE (AP) — Two people in Washington state who recall being sick in December have since had blood tests showing they developed antibodies for the coronavirus, but health officials aren’t counting them in their official case counts. The positive serology tests can’t determine whether the people had the coronavirus in December, weeks before the disease was officially detected in the United States. They may have been exposed after the first recorded case. One of the people had lunch with a hospital nurse in Kirkland, for example, site of a large outbreak in a nursing home. The two people are residents of Snohomish County, which has the second-highest number of confirmed cases in the state with more than 2,700.
