MINNEAPOLIS (WCCO) – A Twin Cities school cancelled classes and activities Thursday after officials say a parent in the community tested positive for the novel coronavirus (COVID-19).

In a letter to parents, St. Thomas Academy, an all-boys school in Mendota Heights, says that the infected person has not been on campus, but the school decided to begin spring break early out of an abundance of caution.

So far, nine people in Minnesota have tested positive for COVID-19, health officials say.

St. Thomas Academy is among other educational institutions responding to the spread of the disease. On Wednesday, the University of Minnesota suspended in-person classes on its five campuses.
