Three residents and one staff member have tested positive for COVID-19 in a "small cluster" outbreak at a Knox County assisted-living facility. Three additional tests of staff members are pending.

The remaining residents have tested negative, said Knox County Health Director Dr. Martha Buchanan.

She refused to name the facility on Wednesday afternoon.

She refused to say how many, if any, of those people were hospitalized.

Buchanan also, when pressed by reporters, refused to say how many residents of the facility tested negative.

She refused to say whether the county's one coronavirus death is connected to the assisted-living facility.

"Because of the low number of people, we are not releasing any patient information," she said.

The Knox County Health Department updated the number of cases in the county as of Wednesday.

There have been 77 cases, including 28 people who have recovered, 12 who were hospitalized (at some point over the course of their illness) and one who died. So far, 1,090 tests have been conducted in Knox County, according to health officials, but they warn that the figure does not include all negative tests.
