In the first edition, three types were described: observed case, confirmed case, and critical case; however, from the second edition onwards, the term "observed case" has been changed to "suspected case, " and the criteria for "severe case" has been added. However, this item was deleted from the second edition onwards, but "a history of contact with patients with fever or respiratory symptoms from Wuhan city within the last 14 days before symptom onset, or with a cluster of confirmed cases" was added.
