A closer review of the asymptomatic COVID-19 cases recorded during the first pandemic wave in the Hunter New England area found that seven of the 26 ‘asymptomatic’ patients actually had experienced COVID-19-like symptoms, with five reporting symptoms prior to testing on review of all available clinical records. There is a need to delve deeper into the symptom history of ‘asymptomatic’ cases than initially recommended in national guidelines.
