Morris MD, MPH, FRCPC, FAAP, DTM&H Divisions of General Pediatrics Clinician-Scientist, Division of Infectious Diseases Division of Infectious Diseases at the Hospital for Sick Children (SickKids) for the Canadian Paediatric Surveillance Program COVID-19 Study Team What is the background for this study?
