COVID-19 diagnoses in the areas of Brookhaven and Dunwoody within the cities’ main ZIP codes have risen 39 cases, according to a DeKalb County Board of Health case tracker.

The local ZIP code diagnoses are at 1,101 as of the county’s Aug. 18 report, compared to 1,062 as of the last report on Aug. 16.

As of Aug. 18, Dunwoody’s main 30338 and 30346 ZIP codes had about 435 cases, which is up 14 cases since Aug. 16.

Brookhaven’t main 30319 ZIP code had about 666, which is up 25 cases since Aug. 16.

The county does not track which ZIP codes had COVID-19 deaths.

ZIP codes do not exactly match city boundaries and, in particular, the Executive Park and LaVista Road parts of Brookhaven overlap with ZIP codes in other areas.

In addition, the data may not be completely accurate because of the amount of cases with unknown ZIP codes, which was 203. Board of health “data cleaning,” where the cases are updated with correct addresses, may cause some shifts in the numbers as the county updates the information.

DeKalb Board of Health spokesperson Eric Nickens said the numbers must be verified before going online, which is why there is a lag between the posting and the report’s date.

DeKalb County in total has 15,388 reported cases and 267 deaths, according to the Aug. 18 report.

DeKalb has the third-most cases by county in the state, according to the Georgia Department of Public Health. It trails Fulton County by about 7,300 cases and Gwinnett County by about 6,700.

30319: 666 (up 25)
