What is contact tracing?

St. Croix County Public Health uses contract tracing to help prevent the spread of infectious diseases like COVID-19. Contact tracing is one of the best tools we have to fight COVID-19.

When a person tests positive for COVID-19, we interview them to determine who they may have been in close contact with while they were contagious. Close contacts are instructed to stay home to monitor symptoms to prevent further spread of the virus.
