The report does not state whether the numbers reflect the coronavirus’s spread, the state of testing, or both.

The statistics, which are based on patients’ home addresses, are not completely accurate due to such factors as a large number of patients whose cities or ZIP codes are unknown. Of those diagnosed, their ZIP code was unknown in 749 cases and their home city was unknown in 2,333 cases. All numbers are preliminary and may be adjusted later, including through “data cleaning” — the reassignment of some cases to a different ZIP code or city after further analysis.
