Case Investigation helps slow the spread of COVID-19. It means finding and talking to people who tested positive for COVID-19, and then finding and talking to all the people who were in close contact with them. If your health department calls, be sure to call back! If you have a cell phone and test positive, we’ll text first to let you know it’s us. health.state.mn.us/diseases/coronavirus/tracing.html #StaySafeMN #MaskUpMN
