(2/5) Children were tested if they had a history of close contact with a known case, had an epidemiological link to an outbreak, had arrived from abroad, or had symptoms suggestive of #COVID19. This means the study is likely representative, as few cases are missed in South Korea.
(3/5) Approximately one-fifth of children (22%) were asymptomatic.
Of the children who were symptomatic, 66% had symptoms which went unrecognised before they were tested.
Only 6 children (9%) were diagnosed at the time of symptom onset.
