"Contact tracing is an activity that is commonly done to interrupt transmission of communicable diseases, or diseases that are passed from one person to another. It is critically important in interrupting transmission of the SARS-CoV-2 virus that causes COVID-19."

"These two terms are commonly confused. Contact tracing is a very specific method for public health intervention that requires in-depth investigation of potential exposure, risk for severe disease, and risk for transmission of the virus to others."

"Alternatively, exposure notification is usually conducted completely digitally on an opt-in basis. This process involves the use of smartphones to create a log of potential close contacts."
