­­­Out of the 629 cases of the novel coronavirus in Minnesota, 173 of them are health care workers, Minnesota Department of Health spokesperson Doug Schultz told CNN.

These numbers suggest that seven in 25 of those who tested positive for COVID-19 in Minnesota are healthcare workers.

Schultz pointed out that “our testing is focused on healthcare workers so the proportions are probably higher than otherwise would be.”

He also noted that not all healthcare workers contracted the virus from their workplace and that most of the positive cases are travel-related.
