Field Briefing: Diamond Princess COVID-19 Cases
Preliminary Results:
As of 18 February, there have been 531 confirmed cases (14.3% of all individuals on board on 5 February), including 65 crew and 466 passengers. A total 2404 respiratory specimens were tested, and 542 were positive (22.5), including double tests. Among confirmed COVID-19 cases with recorded symptom onset (n=184), there were 33 (18%) with onset dates before 6 February, which was the first full day of quarantine, and 151 (82%) with onset dates on or after the 6th. A total 255 (48%) of the confirmed cases were asymptomatic when the respiratory specimen was collected. Of these, 8 were crew and 247 were passengers. (Information on development of symptoms after disembarkation of asymptomatic confirmed cases is not currently available.) A total 23 passengers with reported onset dates were confirmed after another passenger in the same cabin had been confirmed. From 13 February to now, 81% of cases among confirmed passengers or crew with reported onset dates (n=22) occurred in crew (n=13) or passengers from cabins with a previously confirmed case (n=5).
