COVID-19 diagnoses in Brookhaven and Dunwoody’s main ZIP codes rose about 15 cases in three days, according to a DeKalb County Board of Health case tracker.

The local ZIP code diagnoses were estimated at 6,141 cases as of the April 6 report, up from about 6,126 on April 4.

Reports in Dunwoody’s 30338 ZIP code increased from at least 2,342 confirmed cases of the infectious virus to approximately 2,349 diagnoses. The tally in Dunwoody’s other main ZIP code, 30346, rose by four cases.

Brookhaven’s main 30319 ZIP code had about 3,299 cases, up four since April 4.

The county does not track which ZIP codes had COVID-19 deaths, but as of April 6, DeKalb County has reported 55,694 cases and 882 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 360. 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 April 7, 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 28,347 cases, Fulton County by about 23,459 cases and Cobb County by about 3,002 cases.
