On todays episode we interview a disease detective hunting for patient zero and trying to stop the spread of COVID-19. Christian Peut is a Contact Tracer in the Communicable Disease and Control Branch at SA Health. Coronavirus contact tracers or "disease detectives" are the health experts who interview people with COVID-19 to try and work out who they might have got the disease from and who they might have given it to.
