(St. Paul, MN)  --  Minnesota health officials are concerned that COVID-19 cases in long-term care residents have nearly tripled in the last month.  Infections among staff in those facilities have also gone up.  State Epidemiologist Doctor Ruth Lynfield points to a worrisome pattern of long-term care workers clearly having more exposures to COVID out in the community, than in the facilities themselves.  She says they're worried "that the progress that we have made in the state can be at-risk if we let up on our precautions." She says everyone must take proper precautions in public settings by masking and social-distancing.
