COVID-19 diagnoses in Brookhaven and Dunwoody’s main ZIP codes rose about 61 cases in six days, according to a DeKalb County Board of Health case tracker.

The local ZIP code diagnoses were estimated at 6,036 cases as of the March 28 report, up from about 5,975 on March 23.

Reports in Dunwoody’s 30338 ZIP code increased from at least 2,279 confirmed cases of the infectious virus to approximately 2,305 diagnoses. The tally in Dunwoody’s other main ZIP code, 30346, rose by six cases.

Brookhaven’s main 30319 ZIP code had about 3,250 cases, up 29 since March 23.

The county does not track which ZIP codes had COVID-19 deaths, but as of March 28, DeKalb County has reported 54,869 cases and 867 deaths.

Among all DeKalb County positive cases, 7.8% were hospitalized and 1.6% have died.

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 361. 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.

As of March 29, DeKalb has the fourth-most cases by county in the Atlanta metro area, according to the Georgia Department of Public Health. It trails Gwinnett County by about 28,422 cases, Fulton County by about 23,302 cases and Cobb County by about 3,083 cases.
