a Calculated based on the total number of COVID-19 confirmed cases up to May 18.
b Taken as maximum of highest amplitude peak.
C Calculated from date of 0.5% accumulative cases to date of highest amplitude.
d Calculated based on time from the peak of highest amplitude curve to 50% and 90% reduction.
e Not reached (nr) by May 18. Population: Ireland 4.9 M; Germany 83.7 M; UK 67.8 M; South Korea 51.2 M; Iceland 0.36 M.
