The latest round of state-administered testing for novel coronavirus has found that a woman in her 30s from Denver is the third person in the city to test positive.
She has no known contact with an infected person, but does have a recent history of travel in the United States, according to the Colorado Department of Public Health and Environment.
The state health department called the test a “presumptive positive” because officials must send results to the Center for Disease Control for approval. Health officials completed 21 tests between 10 a.m. and 2:30 p.m. on Monday.
Another woman, in her 70s, took a COVID-19 test but results were inconclusive.
“Out of an abundance of caution, CDPHE will treat that individual as a positive case until we receive conclusive results,” the department said in a statement.
The other two cases, a man in his 40s and a woman in her 70s, are unrelated. One is the parent of a child at St. Anne’s Episcopal School, which closed early on Friday as a precautionary measure.
