The Korean CDC reports covid-19 here
KCDC
From the last two batches, The 9am report found 595 cases and the 4pm reported additional 210 cases.
The latest confirmed cases are ~ 800 daily but the new suspected cases are 4x higher. I don't know if suspected means awaiting testing or awaiting confirmatory testing after a positive screening test. The historical results are that ~ 1/2 of the suspected cases are confirmed.
Well, there certainly was a spike on what I have listed as 28 February (but they seem to have credited to slightly later, 29 February), to 910 (315+595). But before that I see 427 (and the day before that, 449), and the day after that, 595. So I'm not sure that "800 daily" is a good description at this point.
