The lab-tested data was also separately available for 10–15 February 2020.
Data from 16 February 2020 onwards did not include a separate number of lab-tested cases.
From 19 February 2020 onwards, only new lab-tested cases were counted towards the total (but clinically diagnosed cases counted earlier were not discarded).
