From the Document: "We all need to work together to help slow the spread of COVID-19 [coronavirus disease 2019]. Contact tracing slows the spread of COVID-19 by  Letting people know they may have been exposed to COVID-19 and should monitor their health for signs and symptoms of COVID-19.  Helping people who may have been exposed to COVID-19 get tested.  Asking people to self-isolate if they have COVID-19 or self-quarantine if they are a close contact of someone who has COVID-19. The messages in this toolkit use COVID-19, but you may want to use 'coronavirus' instead of COVID-19 if that's the term most often used in your community."
