(2) Cases were uploaded to the contact tracing system starting April 6, 2020; earlier cases were tracked through a different process.
(3) Total number of cases is different than the reported current number of cases because cases are removed later if they are identified to be duplicates, out of jurisdiction, or false cases.

(5) Cases missing phone numbers and referred for DMV/Lexis Nexis search.
(6) Cases pending interviewer assignment (e.g. cases with newly found phone numbers from DMV/Lexis Nexis search and interviewer staffing factors).
