The importance of screening cannot be over-emphasized.  Screening helps to identify patients who are possibly infected with COVID-19 before they enter a clinic, receive care and possibly transmit the virus in the process.  Pre-screening (telephone screening) should be done prior to the day of the appointment (when feasible), in addition to in-person screening on the day of the appointment.  Screening must include COVID-19 symptoms and COVID-19 risk factors.
