COVID-19 Contact Tracing
Contact tracers work with people who have COVID-19 to let their close contacts know they may have been exposed to the disease.
Making a choice to work with contact tracers helps protect you, your family and your community by slowing the spread of COVID-19.
Contact tracers will never ask for your social security number, bank information or credit card number.
