"# of cases" includes both confirmed and probable cases, with 44,111 probable cases identified as of 8 April 2024.[14] The number of new cases reported for each date appears in brackets next to the # of cases.
Asterisks (*) and carets (^) denote dates in which the number of new, active cases (in brackets) reported does not equal the increase in total # of cases (compared with the # of cases from the previous date):
Asterisks indicate that one or more previously reported cases have subsequently been reclassified: a previously confirmed case may have been removed, or a previously removed case may have been reconfirmed. Discrepancies may also be due to data updating and reconciliation.
Carets indicate that the # of cases includes one or more historical cases that were considered already recovered at the time of reporting. These are not considered new, active cases, but have still been added to the total # of cases.
