It remains unclear whether the rise reflects an increase in the coronavirus’s spread, an increase in 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. Another factor is “data cleaning,” where a few cases may shift from one city to another between reports. The May 8 report shows two cases removed from Buckhead and Sandy Springs ZIP codes due to data cleaning.

The total number of confirmed COVID-19 diagnoses in the county as of May 8 was 3,321, up from 3,279 on May 6. Of those, 137 died, or about 4.1%; about 18.4% were hospitalized. Atlanta remains the number one city in the county for COVID-19 diagnoses at 45.5% of the total, and Sandy Springs remains in third place with 8.1% of the total.

Of those diagnosed, their ZIP code was unknown in 266 cases and their home city was unknown in 433 cases.

The number of diagnosed cases in each main ZIP code in Buckhead and Sandy Springs stayed about the same between the May 6 and May 8 reports. They include:

Buckhead ZIP codes
